1. Introduction
Sustainable development (SD) in Higher Education Institutions (HEIs) has been a global topic in recent decades, with a growing awareness of the role of the university in SD promotion [
1]. The growing concerns of resource consumptions at campus level and the growing trend of sustainability promotion in society strengthen the discussion of SD promotion in HEIs [
2]. There are various means to SD, such as technology transfer, sustainable production, finance, and consumption that acquire tremendous professional knowledge and technical skills, implying that education is serving as one of the pillars to obtain SD goals [
3]. HEIs have played a critical role in achieving transformative changes in society by preparing future professionals, academics, leaders, managers, and decision-makers [
4,
5]. Particularly, the collaboration with all sections of the university system is essential, which includes education, research, campus operations, and community outreach [
4]. Moreover, an increasing number of SD-related missions and declarations in HEIs have been launched in response to the ongoing concerns of sustainability and to guide universities to perform sustainably [
6]. HEIs have started to sign some of the declarations such as Talloires Declaration, the Halifax Declaration, and the Copernicus University Charter for presenting their commitment to SD and to effectively incorporate SD into university systems [
6]. Researches also suggested that HEIs usually sign more than one declaration, and those HEIs with greater commitment tend to undertake more SD actions [
6].
Analysis of SD on campus varies significantly worldwide, but they all emphasized the unique and critical role of education in promoting SD and raising the awareness of being a socially and environmentally responsible citizen by actively participating in real practices [
2]. The face-to-face SD courses are traditionally and commonly adopted by HEIs, while some scholars started to access the effectiveness of using e-learning in SD promotion [
7]. It is observed that previous studies that addressed sustainability issues of HEIs are largely conducted in western developed countries [
8]. For instance, earlier studies revealed that most students have a positive attitude towards SD in the UK and Australia [
9,
10]. Similar studies of SD in HEIs began to focus on developing countries like China, Iran, Malaysia, Saudi Arabia, and Turkey in last decade [
1,
8,
11,
12,
13]. However, it is vital to notice that the education system in developing countries might be different from that in developed countries. Particularly, China is one of the countries, having a large number of HEIs, which also occupies a vital proportion in the Chinese economy [
14]. Given that HEIs make an immense impact on SD promotion on whole communities, Chinese government announced that HEI is a key factor to realize sustainability in the state, and launched several strategic plans and regulations to foster the pace of achieving SD goals [
15,
16].
Not surprisingly, an organization can cause externalities to various parties, namely stakeholders, which are both internal and external to operation [
17]. As a result of these externalities, organizational practices may be influenced by key stakeholders around them. From the perspective of HEIs, the related stakeholders consist of top management of the university, students, staff, faculty, alumni, community, employers, and funding institution [
18,
19]. The success of sustainable development goals (SDG) cannot be achieved without the engagement and cooperation of various stakeholders [
20]. Given that students are one of the crucial stakeholders in campus sustainability promotion, assessing their perceptions and participation of sustainability issues are significant for the university to reconsider and redesign their initiatives to SD. Besides, businesses are now recruiting graduates with a strong sense of sustainability with adequate knowledge and skills, leading to increasing demands of SD in HEIs. Earlier studies investigated the ways of improving campus sustainability through surveying students’ perception on SD [
11,
21]. The higher level of students’ awareness to sustainability issues is found to positively impact on environmental practices, whilst the reduction of students’ carbon footprint can be attributed to the growing awareness on SD [
22]. Some previous studies also focused on examining students’ commitment to sustainability, practices in real life, and their views on the role of the university in SD promotion [
8,
23,
24].
HEIs in China actively participate in SD through campus operations and sustainability-related education provided to students [
1]. In general, there are two types of HEIs in China, which are private university and public university (By the end of 2019, there were a total number of 2663 regular HEIs in mainland China where 1914 public HEIs and 749 private HEIs. The information can be found at:
http://www.moe.gov.cn/s78/A03/moe_560/jytjsj_2018/qg/201908/t20190812_394215.html). Similar to the rest of the world, private universities in China generally receive funds from students’ tuition fees and possibly some donations from a third-party, while public universities are fully funded by the nation [
25]. Private universities, therefore, suffer a greater financial burden, where over 90% of revenues are from the tuition fees, consequently affecting the campus operation efficiency, recruiting process, education, and research quality [
26,
27]. Administration freedom is another feature that applies to private universities, where they can arrange a more innovative curriculum and learning environment [
28]. It is not surprising that private HEIs in China feel pressures to attain a higher rate of enrolment for survival because of the limited funds, forcing them to continuously improve their reputation [
26]. Pervious researchers argued that the greater participation in SD would better improve public image of a university and therefore differentiate itself from other competitors, attracting more upcoming students [
29,
30].
In the Chinese context, it is not surprising that private HEIs have different sources of funding and social reputation compared with public HEIs. Although there are a certain number of earlier studies that investigated SD of HEIs in the Western countries like U.S. and Europe [
12], there are very limited studies in China that explored the comparison between public and private HEIs in SD from students’ point of view. As such, this study will contribute to fill this gap by managing a case study on universities in Guangdong province, one of the most developed areas in China. Two Chinese universities are selected for comparison: A public university—Zhongkai University of Agriculture and Engineering (ZHKU), and a private university—Gunagzhou College of South China University of Technology (GCU). By using the bottom-up approach, students are surveyed to examine their perception on sustainability issues. The reason for starting from students’ perspective is that their value, outlook on life, and particularly their sustainability awareness is intimately fostered by the university.
The rest of this paper is organized as follows:
Section 2 presents the literature review;
Section 3 entails the methods;
Section 4 presents the results and discussion, and the last section presents the conclusion.
3. Methods
3.1. Study Area
A public university in China, Zhongkai University of Agriculture and Engineering (ZHKU), and a private one, Guangzhou College of South China University of Technology (GCU), were chosen to compare students’ perception of SD. In order to gain permission from these two universities, we have respectively sent requests to the “Sustainable Development and Planning Section” office of ZHKU and the department of students’ affairs of GCU in early September. The consents were received in a timely manner.
Founded in 1927, the ZHKU has a total student population of 21,579 studying in 17 schools and is one of the centuries-old universities to promote agricultural development in mainland China. The main campus of ZHKU is located in Guangzhou city, the capital of Guangdong province, and a distance of about 3 kilometres from the city centre. In order to advocate SD, ZHKU has established a specialized division, so called “Sustainable Development and Planning Section”, to promote campus sustainability. The division is governed under rector office and actively involves in clarifying ZHKU’s sustainability visions, developing annual target of sustainable manners, and directing sustainable activities. The private university, GCU, which was founded in 2006, is located in Huadu district of Guangzhou city, with a distance of about 10 kilometres from the airport and 40 kilometres from the city centre. GCU is one of the top three private universities in Guaugdong province, offering 41 undergraduate programs within 13 schools, and has over 22,000 students. GCU has developed solid connections between SD and curricula by integrating sustainability education into academic program. Compulsorily, all GCU’s bachelor programs are required to include at least one sustainability course in their curricula, regardless of majors in art, business, science, or engineering.
3.2. Survey Instrument
For understanding students’ perception on SD, a survey using self-administrated questionnaire was delivered during October 2019 in ZHKU and GCU (
Appendix A), respectively. The construct of survey is based on the integration of Emanuel’s questionnaire [
24] and the Sustainability Assessment Questionnaire (SAQ) [
60] for assessing students’ personal commitment and practices, and their perception about university’s achievement on some important dimensions of campus SD. In order to optimize the survey’s validity for Chinese HEIs, we made some modifications in terms of Chinese language conversion and cultural gap alleviation. The survey comprises of five sections with a total of 24 questions. The first section is concerned with the demographic information of respondents. The second section, consisting of three items, is established to investigate students’ commitment to SD. The third section provides two sustainability-related multiple choices, in order to examine students’ instant knowledge of sustainability issues. The fourth section explores the attitude of students on the extent to which the university, the degree program, and individual engagement comply with sustainable principles. Three subsections are developed to examine, for instance, the university’s role in promoting SD, the curricula and research covering sustainability issues, and students’ involvement for SD in HEIs. The last section is to discover students’ sustainable practices, by asking whether or not they currently recycle, carry out energy saving practices, use environmentally friendly products, and/or have green transportation.
Unlike the first section, which relates to respondents’ current demographic information, the questions in the second section, fourth section, and fifth section are closed-end, demanding respondents’ answers on a five-point Likert scale, which ranges from 1 (represents strongly agree) to 5 (represents strongly disagree). The questions in the third section are also rigidly structured, requiring respondents to choose the most correct option from lists of five terms that they do or do not associate with sustainability. In order to validate the questionnaire, three academic experts in the field of business education were asked to preliminarily review the content in line with the established goal of the questionnaire. Some questions have been modified based on experts’ comments and suggestions. The pilot survey was then delivered to a small group of 30 students, for checking whether or not the questionnaire is clearly interpreted without ambiguities. Minor revisions were also made after the pilot test, and then finally acquired a modified Chinese version of the survey.
The questionnaire was distributed to students through classroom, which allows us to directly get access to students and gather information, as well as point of view, promptly. We dispensed the questionnaire during the autumn semester of the 2019–2020 academic year. It takes less than five minutes for students to complete.
3.3. Sample
Respondents of this study consist of a total of 393 and 347 students in ZHKU and GCU, with response rates of 79.3% and 84.2%, respectively. The sample of the total student population represents 1.8% in ZHKU and 1.6% in GCU. All respondents from ZHKU and GCU are currently pursuing only bachelor’s degree, and no postgraduate takes part in the survey. Respondents are from School of Management of ZHKU and International Business School of GCU. The reason for only administrating questionnaires to students with a business major is that we could not assure acceptable number of respondents who are majoring in science and engineering subjects. We also confirm that the nature of participation is voluntary, and the information collected from respondents is confidential.
3.4. Analysis
In terms of statistical analysis, the frequency distribution is conducted to analyse students’ responses to each question. The percentage is used in illustrating frequency distribution, for acquiring standardized comparisons between two universities and among questions. The Pearson’s chi-square statistic is also implemented to examine whether or not the distribution is statistically different to one another. All analyses are found at the 0.05 level of significance, indicating that there is a statistically significant difference among questions analysed.
5. Conclusions
HEIs may influence on society to a significant extent and contribute to SD through fostering students’ personal identity and value. This study probes into students’ perception about SD on one public and one private university. Four sections consisting of commitment, knowledge, attitude, and practices toward SD are examined for comparing students’ opinions of ZHKU (public university) from that of GCU (private university). In general, students from these two universities have greatest concern with the commitment regarding the preservation of resources for future generations, followed by the university’s role for promoting SD. In contrast with earlier studies, which suggested the highest priority for environment sustainability, there is a neutral concern with environment-related issues among our respondents. It is also found that students lack willingness to proactively practice sustainable activities in their daily life, and generally perceive the least important to promote SD into curricula, programs, and research. In terms of the comparison between the public and the private university, students in the private university more often agree on the importance of SD than their public counterpart.
The current study provides several implications to promote SD in Chinese HEIs. First, the top-down approach to address sustainability issues is criticized by the lack of incentive and students’ participation [
52]. Policies and action plans only designed by university administration hardly represent students’ perception on SD. Instead, a bottom-up approach is better to utilize, by the ways of decentralizing decision making to students, staff, and faculty. The self-imposed sustainable plans and provisions are more accurate and reliable than estimates prepared by university administration who have less intimate knowledge of courses, projects, programs covering sustainability issues, and day-to-day campus SD. The bottom-up approach also helps to construct a dynamic environment where interaction between university administration and students is efficient and active. In this regard, some communication tools such as anonymous SD-related questionnaires can be carried out for constructing a bridge between university administration and students. Incentives on students’ SD engagement can be also developed. Second, the less concern with sustainability-related curricula and research among students presents opportunities for universities to consider implementing inclusive education, such as offering a wide choice of sustainability courses and embedding some sustainability credits in total graduation credits. Particularly, students in the public university are found to have lower level perception of sustainability curricula, reflecting that public universities need to engage environmental preservation and social well-being into general education purpose. Third, regulatory authorities need to launch policy guidelines to mandate university administration for SD promotion. For instance, the Ministry of Education can establish a set of best SD practices, helping Chinese HEIs to benchmark themselves. In addition, the local bureau of education can form an independent section/department to periodically regulate and assess university’s sustainable practices. Testimonials and awards can also be given to HEIs with best SD practices.
As usual, some limitations need to be acknowledged. First, the survey of this study using self-administrated questionnaire is only based on literature review. There are only twenty-one questions of SD designed in the questionnaire, implying the insufficient size to cover all aspects of students’ perception about SD. Given students’ lax attitude and the lack of incentives to complete the questionnaire, we try to minimize the number of questions in order to shorten the completion time and gain more commitment from respondents. Second, the number of universities selected in the current study is inadequate. The sample biases may arise due to only one public and one private university being compared. It would be better to have more universities for achieving more representative and reliable results. Third, only students majoring in business participated in the questionnaire, generating some bias to represent all students with different backgrounds. Future research may extend to figure out how HEIs practically incorporate environmental preservation and social well-being into general education purpose. Other stakeholders, such as faculty, staff, and alumni, and different types of universities, such as research-oriented and vocation-oriented universities, can be investigated. Future direction can be also linked to a cross-county analysis of SD in HEIs. From practitioners’ point of view, university administration of Chinese HEIs can run some SD-related communication mechanisms, such as regular check of campus SDG implementation and assess students’ feedback on SD issues.
