1. Introduction
The obstruction of traditional channels has led to a large number of unsold agricultural and sideline products since the outbreak of COVID-19 in 2019. To help farmers avoid poverty, government officials at all levels promote agricultural and sideline products using a livestreaming e-commerce method. Livestreaming e-commerce breaks the bottleneck of insufficient information interaction in traditional e-commerce and reduces the information asymmetry of transactions, thus improving consumers’ purchasing intentions [
1]. As an e-commerce company, Alibaba data show that, in the first quarter of 2020, more than 600 mayors sold agricultural products through livestreaming to achieve sales of 6 billion CNY [
2]. The data from TikTok show that government officials sold more than 2.475 million agricultural products through livestreaming in the first half of 2020, with sales exceeding 118 million CNY [
3]. In 2020, “Thank you for making orders for Hubei” launched by CCTV media was only a 2 h livestreaming e-commerce on 6 April. The cumulative number of viewers reached more than 120 million, with total sales of about 40.14 million CNY [
4]. The livestreaming e-commerce of agricultural and sideline products realizes the efficient docking of supply and demand through an innovative transaction model. The livestreaming e-commerce of government officials has helped farmers avoid poverty, improved the government image and social governance, and increased citizens’ trust in the government [
5].
Compared to traditional e-commerce platforms for agricultural and sideline products, livestreaming e-commerce has innovative features. First, streamers actively attract purposeless consumers by dynamically displaying rich, diverse, interesting, and useful content and information, thereby creating consumer demand [
6,
7]. Second, livestreaming creates a “face-to-face” information interaction context that can more accurately and quickly respond to consumer demands and narrow the emotional distance with consumers [
1]. Third, credible government officials, authoritative media, and celebrities livestreaming agricultural products have the advantage of quality endorsement. When consumers believe that the quality of agricultural products is safe and reliable, they are more inclined to make purchasing decisions. Fourth, as an innovative function of livestreaming, a bullet screen is the main way for viewers to interact with each other. Viewers can use bullet screen comments sent by others as shopping references [
8]. Consumers can better evaluate products and make purchasing decisions by obtaining real-time, dynamic, and multidimensional information. In sum, livestreaming e-commerce enhances consumers’ shopping experience and materializes potential purchases by providing comprehensive information.
Livestreaming e-commerce has greatly exceeded e-commerce platforms and offline platforms, leading to the explosive growth of livestreaming platforms, such as Facebook and YouTube in the United States, and TikTok, Taobao, and Pinduoduo in China. Livestreaming e-commerce, as a new form of shopping, is becoming increasingly popular. However, thus far, livestreaming e-commerce research is still in its infancy. Existing research mainly examines the antecedents of consumers’ intention and motivation to purchase general products [
1,
6,
9], the interaction between consumers and streamers (e.g., virtual gifts) [
10], and consumer participation behaviors [
11,
12,
13]. Unlike celebrities’ livestreaming e-commerce, the essence of government officials’ livestreaming e-commerce is to develop the rural economy and increase farmers’ income. To achieve the goal of rural revitalization, government officials have promoted rural specialty products through livestreaming [
5]. Government officials’ livestreaming e-commerce has realized an efficient connection between farmers’ supply and citizens’ needs and has become an important method of poverty alleviation under an epidemic. However, studies on the role of government officials’ livestreaming e-commerce in influencing consumers’ purchasing intentions are lacking.
Previous research has taken gender [
14], knowledge [
15], and the need for belonging [
16] as the moderators of consumers’ purchase intention. With an increase in shopping channels, Floh and Madlberger [
17] found that impulsiveness, as an individual’s psychological characteristics, plays an important role in consumers’ decision-making behavior. Chang et al. [
18] used the elaboration likelihood model (ELM) to explore the antecedents of consumers’ purchase intentions in the Facebook’s secondhand marketplace. They found that impulsiveness positively affects consumers’ purchase intentions. Conversely, Chopdar and Balakrishnan [
19] found that impulsiveness negatively affects consumers’ purchase intentions in the context of mobile shopping. This contradictory result motivates us to investigate the role of impulsiveness in the context of livestreaming e-commerce. Furthermore, empirical research on the effect of impulsiveness on purchase intention in the context of livestreaming is just beginning and, therefore, limited.
Impulsiveness refers to an individual tendency that includes urges to engage in an unplanned action or to take action immediately without evaluation or deliberation of consequences [
20]. The characteristics of impulsiveness differ among consumers. Individuals with higher discrepancies between their real self and their ideal self tend to purchase impulsively [
21]. Existing studies have confirmed that, when highly impulsive consumers perceive that websites provide high-quality information, they are more likely to purchase products [
18,
19]. The streamer offers product information in real-time video during livestreaming. At the same time, consumers can ask for product information through a bullet screen, and the streamer can rely on livestreaming to provide consumers with personalized information and services. Therefore, when highly impulsive consumers watch livestreaming, they are more likely to purchase products without thinking because of the positive emotions generated by the livestreaming content, streamer, or livestreaming environment. However, research on the role of impulsiveness in the context of livestreaming is scarce.
Considering the abovementioned gaps, this study mainly addresses two questions: (1) What are the key antecedents affecting consumers’ purchasing intentions in the context of government officials’ livestreaming e-commerce? (2) Does impulsiveness affect consumers’ purchase intentions in the context of government officials’ livestreaming e-commerce?
To answer these research questions, this study uses the S–O–R framework to examine the effect of platform factor (information quality), user factor (bullet screen mutuality), and streamer factors (streamer reliability, streamer responsiveness, and streamer trustworthiness) on perceived information usefulness and arousal, which affect purchase intention. The moderating effect of impulsiveness is also examined. This study contributes to the existing literature. First, this study focuses on the predictors of purchasing agricultural and sideline products. Previous livestreaming e-commerce literature did not consider specific product categories. Second, credible government officials pay more attention to product quality. If the products purchased by consumers are expired, deteriorated, or crushed, the government’s image will be severely damaged, thus reducing citizens’ trust in the government. Third, the extant literature has integrated impulsiveness into various contexts for research. This is one of the few studies using the S–O–R paradigm to investigate the antecedents affecting consumer purchase intentions in the setting of livestreaming e-commerce.
The remainder of this paper is structured as follows: First, we search the literature on livestreaming e-commerce, impulsiveness, and the S–O–R framework in detail to naturally and smoothly elicit research questions. We then develop the research model and discuss the research methodology and empirical results. We present the theoretical and practical implications, limitations, and future research trends. Finally, the conclusions are presented.
3. Research Model and Hypotheses
Information quality refers to the measurement of how highly the quality of information provided by the system matches the needs of users [
60]. Information quality encompasses system characteristics such as usefulness, comprehension, relevance, accuracy, and timeliness. High-quality information is easy to understand, accurate, timely, reliable, relevant, and complete [
60,
61,
62]. Due to the information asymmetry between producers and consumers, high-quality product information plays an important role in consumers’ deliberated evaluation of the actual state of products [
63,
64]. Previous research has shown that high-quality information is useful and valuable. For example, when a social commerce website provides consumers with high-quality information about related products or services that they need in a transaction, consumers perceive the information and the website to be useful [
60,
63]. In addition, mobile commerce, which provides high-quality information, enables users to obtain the information they need promptly during the shopping process. Consumers who obtain high-quality information greatly reduce the time they spend on mobile shopping, thereby enhancing their perceived information usefulness [
65,
66]. Applying this logic, the information quality of this study refers to the extent to which government officials’ livestreaming provides consumers with complete, accurate and timely product information. Government officials, as streamers, show and provide product information in the form of videos, and they answer questions raised by consumers on the bullet screen in real time. When government officials provide consumers with complete (i.e., product details, experience sharing, and promotion information), accurate (i.e., clearly displays the actual state of the product), and timely (i.e., timely interaction with the audience and providing them with the latest product information) product information during the livestreaming, consumers believe that livestreaming content has high information quality. Consumers use the high-quality information obtained from livestreaming to evaluate products and guide purchase decisions. Therefore, high-quality livestreaming information makes consumers perceive the information as useful, helping them make informed decisions. Therefore, we hypothesize the following:
Hypothesis 1 (H1). Information quality positively affects consumers’ perceived information usefulness.
Mutuality refers to consumers’ exchange of shopping advice about a brand or the sharing of product information or recommendations with other consumers on a social media platform [
67,
68]. In view of the fact that mutuality can help peers solve product use problems by using social media platforms (i.e., Facebook, Instagram, and WeChat) to share product purchase experiences and suggestions, marketers, and managers invest significant resources to facilitate mutuality [
69]. A bullet screen is a type of comment that scrolls on the screen in real time. It is the main way of interaction between viewers during livestreaming [
1]. Compared to a traditional video bullet screen, the content of a livestreaming bullet screen has higher value to the audience. On one hand, the audience can watch the bullet screen information sent by the co-viewer in real time or obtain product information through the interaction between the co-viewer and the streamer [
22]. On the other hand, the audience can also raise questions about product information (product size and price) through the bullet screen. By increasing their knowledge of the product, the audience can reduce product uncertainty due to information asymmetry [
6]. In addition, mutuality can increase the positive arousal of users. When users obtain useful information from the barrage of information provided by their co-viewers, their favorability of the live broadcast increases, stimulating the audience’s psychological arousal. Pop-up messages (i.e., co-viewers’ likes, gifts, purchases, and new viewers entering the livestreaming room) also inspire positive emotions among viewers [
10]. Several studies have shown that mutuality has a significant positive relationship with perceived information usefulness and arousal. For example, high-quality social interaction increases users’ understanding of the platform and products and is less susceptible to interference from sellers or platforms in the context of social commerce. As users receive rich and adequate product information, they perceive the information as useful and have positive emotions, including enjoyment and arousal [
70]. Mutuality enables viewers to understand the views of other viewers on the streamer and the product, thereby affecting their cognition and arousing mental models. Therefore, we hypothesize the following:
Hypothesis 2a (H2a). Bullet screen mutuality positively affects consumers’ perceived information usefulness.
Hypothesis 2b (H2b). Bullet screen mutuality positively affects consumers’ arousal.
Source credibility is defined as the extent to which an information source is perceived to be believable, competent, and trustworthy by the information recipients [
71,
72]. The streamer is the viewers’ main source of product information in the context of livestreaming e-commerce. Streamer trustworthiness refers to the degree to which the streamer is regarded to have honesty, integrity, and believability by livestreaming viewers [
73]. During the livestreaming of the streamer, the viewers can judge the trustworthiness of the streamer in two ways. First, viewers can judge by the bullet screen information sent by other viewers, likes, gift-giving behaviors, and the performance of other viewers in the process of interacting with the streamer. If the viewers’ evaluation of the streamer is more positive and the behaviors of likes and gifts are more frequent, then the streamer is more credible. Second, viewers can use livestreaming information, such as the number of fans of the streamer and the number of online viewers. A greater number of streamer fans and online viewers is correlated with a higher streamer’s trust. Unlike celebrities or company representatives, government officials who endorse the credibility of the government introduce agricultural products to viewers and send a signal of reliable quality. Government officials pay more attention to the quality of agricultural products to prevent damage to the government’s image. The viewers believe that a higher trustworthiness of the streamer reflects a higher usefulness of the information they perceive. Sussman and Siegal [
71] argued that information provided by trusted sources is more useful. Osei-Frimpong et al. [
73] believed that the information provided by a trusted spokesperson is more reliable and useful. In addition, honest and trustworthy streamers bring positive emotional experiences to viewers. If the information receivers perceive that the spokesperson is trustworthy, they tend to have more preferences and emotions for the spokesperson and the products endorsed by the spokesperson [
74]. Similarly, in the context of livestreaming, when the streamer has a high level of trust, viewers have a positive emotional attitude toward the products they recommend. Therefore, we hypothesize the following:
Hypothesis 3a (H3a). Streamer trustworthiness positively affects consumers’ perceived information usefulness.
Hypothesis 3b (H3b). Streamer trustworthiness positively affects consumers’ arousal.
Source expertise refers to the extent to which a source is believed to be capable of making valid assertions [
75]. Some consumers may have relatively limited purchasing experience, professional knowledge, and related product information for a certain product; thus, they have a sense of hesitation and uncertainty before purchasing [
6]. Viewers can judge the expertise of the streamer through their familiarity with the product and their professional analysis ability of the product. Furthermore, whether the streamer can accurately, objectively, and professionally answer the questions raised by the viewers through the real-time bullet screen can also reflect the professional level of the streamer during the livestreaming. The streamer can clearly convey product-related information through their own high degree of professionalism, including multisource product information, rich practical experience, and a high degree of product knowledge [
76,
77]. An anchor with professional knowledge can provide a more comprehensive introduction to the product. Source expertise is considered useful, accurate, and reliable because it reduces viewers’ efforts to process product information. For example, suggestions provided by members with higher expertise are more useful in the context of social shopping [
75,
77]. Biswas, Biswas, and Das [
78] found that individuals who are more specialized in high-tech products have more influence on consumer decision making in advertising. In addition, source expertise can promote users to have a positive emotional experience with the recommended products [
79,
80]. For example, Bhattacherjee and Sanford [
81] believed that peripheral route cues (i.e., source expertise) stimulate user’s emotional response. In this study, the streamer vividly introduces the growth environment, freshness, and eating methods of agricultural products to viewers through tasting, and they even show some talents related to the agricultural products (i.e., tea art performances). Complete and professional information on agricultural products not only increases consumers’ knowledge but also improves consumers’ emotional feelings. Therefore, we hypothesize the following:
Hypothesis 4a (H4a). Streamer expertise positively affects consumers’ perceived information usefulness.
Hypothesis 4b (H4b). Streamer expertise positively affects consumers’ arousal.
Responsiveness refers to the extent to which consumers receive quick and effective responses from customer service staff or sellers [
82,
83]. The responsiveness of the streamer is considered a type of direct communication between the streamer and the consumers, eliminating the barriers of time and space in the context of livestreaming e-commerce. The streamer can highly interact with consumers by relying on the real-time and visibility characteristics of the livestreaming platform [
8]. During the interaction, consumers can fully understand the product, such as its place of origin, quality, price, and efficacy. At the same time, consumers’ sense of experience also improves. Consumers can get relaxation and pleasure while obtaining product information [
11,
84]. Katakam et al. [
85] believe that the demeanor, language, and skills of the salesperson play an important role in consumers’ handling of product information. Salespersons who use flattery selling tactics and matching incidental similarities are more likely to interact with shoppers. The high level of interaction between salesperson and shoppers enables consumers to obtain complete product information. Hu et al. [
86] argued that IPA embedded with machine learning and natural language understanding can analyze and process user behavior and emotional information through a high degree of interaction with users and, in turn, provide a caring, kind, and warm experience. In this research, live streamers can quickly and effectively respond to inquiries or requests from customers in the livestreaming room, including cooking methods and eating methods. Some anchors even humorously respond to the viewers’ questions. The anchor’s real-time response not only improves the convenience and pertinence of communication but also saves the time cost of consumer information acquisition. In addition, frequent interactions prompt consumers to feel disconnected from reality. Therefore, we hypothesize the following:
Hypothesis 5a (H5a). Streamer responsiveness positively affects consumers’ perceived information usefulness.
Hypothesis 5b (H5b). Streamer responsiveness positively affects consumers’ arousal.
Perceived usefulness refers to the degree to which a person believes that using a particular system would enhance their job performance [
87]. Useful information is more valuable because users can make more informed decisions based on this information. Previous studies have shown that perceived information usefulness is a key variable for predicting users’ purchase intentions. For example, social commerce websites that provide users with high-quality information about products or services they need during transactions increase their shopping intentions by reducing shopping time [
88,
89]. Racat, Capelli, and Lichy [
90] argued that there is a strong association between perceived information usefulness and online purchase intention. Applying this logic, the host can efficiently convey useful information and valuable suggestions to help consumers make purchase decisions, such as product descriptions, purchase procedures, and after-sales services. The more useful viewers perceive the anchor’s information, the more likely they are to buy the products recommended by the anchor. Therefore, we hypothesize the following:
Hypothesis 6 (H6). Perceived information usefulness positively affects consumers’ purchase intention.
Arousal refers to the extent to which people feel excited, alert, stimulated, awakened, and positive in a situation [
91]. According to the S–O–R model, the emotional experience generated by the interaction between individuals and the environment will determine their behavioral response. In a pleasant environment, arousal directly leads to the generation of behavioral goals, such as impulse buying [
92,
93], participation [
54], sharing [
94]. Previous studies have demonstrated that consumers’ emotional arousal has a positive impact on their purchase intention. Ning Shen and Khalifa [
95] found that consumers with positive psychological arousal tend to spend more time and energy to explore the website and purchase products in a pleasant online environment. Chebat and Michon [
96] and Barsade et al. [
97] believed that well-decorated retail stores can stimulate consumers’ arousal, leading to longer stay in the store and more purchases. In the context of livestreaming e-commerce, consumers who have a good impression of the product or service are more likely to purchase it. When viewers feel that the livestreaming content is comprehensive, accurate, and professional, they tend to have a positive impression of the livestreaming, generating purchase intention. In addition, viewers’ behavior is also susceptible to the influence of other participants. The viewers can judge the attitude of their co-viewers toward the livestreaming based on the comments, gifts, or purchases of other viewers. The positive attitude of co-viewers affects the current audience’s attitude toward livestreaming, thereby stimulating the existing audience to make similar behaviors. Therefore, we hypothesize the following:
Hypothesis 7 (H7). Arousal positively affects consumers’ purchase intention.
Impulsiveness is a personality trait that reflects the difference in the purchasing intentions of consumers to a certain extent [
18]. Puri [
41] found that consumers with different degrees of impulsiveness can make different behavioral decisions after receiving the same marketing stimulus. Specifically, individuals with a higher level of impulsiveness are more likely to make purchase decisions, while those with lower levels of impulsiveness may lead to fewer purchases. Therefore, individuals with high impulsiveness may not carefully consider or evaluate external stimuli, thus showing unplanned behavior [
20]. The moderation of impulsiveness has been confirmed in previous studies [
18,
34,
77]. Chang et al. [
18] indicated that the effects of attitude toward purchase intention are positively moderated by impulsiveness in the context of e-commerce. Zafar et al. [
77] argued that impulse buying tendency has a moderating effect on consumers’ sentiments and urge to buy impulsively in the context of m-commerce. Wells et al. [
34] found that impulsiveness moderates the relationship between information quality and impulse buying. In this study, when highly impulsive consumers perceive that the product information provided in the livestreaming is useful, they are more likely to purchase products without thinking. In addition, highly impulsive individuals are more likely to be awakened by stimuli. Highly impulsive consumers may buy products due to their appeal rather than necessity. Therefore, we hypothesize the following:
Hypothesis 8a (H8a). Impulsiveness positively moderates the relationship between the perceived information usefulness and consumers’ purchase intention.
Hypothesis 8b (H8b). Impulsiveness positively moderates the relationship between arousal and consumers’ purchase intention.
