1. Introduction
Eradicating poverty is not only the first of the United Nations Sustainable Development Goals [
1], but also a paramount objective for pursuing equitable and sustainable development worldwide [
2]. Poverty and health are intertwined. Before the COVID-19 pandemic, each year close to 100 million people were pushed into extreme poverty because they had to pay for health expenses out of their own pockets [
3]. The fallout from the pandemic threatens to push over 70 million people into extreme poverty [
4]. Meanwhile, the social insurance system is inadequate, especially in low- and middle-income countries [
5]. The World Health Organization noted that the government covers nearly 70% of health care spending in high-income countries, while the value is approximately 30% in low-income countries [
6]. At the current rates of progress, up to 5 billion people will lack health care in 2030 [
7]. The inefficient social insurance system is difficult to improve in the short term. Therefore, enhancing the ability of poor rural households to cope with health shocks may be a plausible path to accelerating progress towards world poverty reduction.
Differing from the poverty criterion of the World Bank, according to which people are poor when they live on less than 1.9 USD per day, in China, the Two Assurances and Three Guarantees (the Two Assurances and Three Guarantees refer to assurances of adequate food and clothing and guarantees of access to compulsory education, basic medical services and safe housing for impoverished rural residents) are utilized to identify poor rural households. If rural households fall below the level of acceptability on any of these indicators, they are identified as poor rural households and their household members are considered as poor population. Moreover, to accurately assist poor rural households, the government set up the Chinese Poor Population Tracking Dataset [
8,
9], which records the poverty causes, support policies and other basic information of registered poor rural households. Hence, poor rural households are also called registered poor rural households because they are contained in the Chinese Poor Population Tracking Dataset. Health shocks affect both poor rural households and non-poor rural households. The difference lies in that the adverse effects are more likely to be fatal for the former than for the latter. Thus, this paper analyses the ability of poor rural households to cope with health shocks and the deficiency of existing intervention policies from the general rural household perspective.
The ability of rural households to cope with health shocks is affected by their own characteristics and by external intervention policies. For rural households, these factors have been well documented and include the household labor supply [
10], educational level and family members engaged in non-agricultural work [
11], the endowment of household wealth [
12], household size, the gender and age of the household head and housing characteristics [
13]. Moreover, in most cases, rural households cannot successfully cope with health shocks by themselves. In fact, the adverse effects of health shocks have two causes. Firstly, health shocks to household members may directly incur a sizable out-of-pocket medical expense. Secondly, health shocks often lead to a loss of labor days or lowered productivity for affected household members and their caregivers [
14], which directly reduces their household income [
15]. To respond to these adverse effects and the catastrophic economic expenditures brought about by health shocks, rural households in most low- and middle-income countries have to resort to income, savings, borrowing, spending reduction, loans or mortgages and engage in livestock and natural product sales [
16]. To compensate for lost labor days and income, a household may reallocate family members and reduce investment in human capital, such as substituting intra-household labor, hiring external labor and withdrawing children from schools [
17]. The coping strategies of rural households not only fail to effectively cope with health shocks but also aggregate the adverse impact of health shocks on their livelihoods. Therefore, some studies have called for more intervention policies to enhance the ability of rural households to cope with health shocks [
5,
18,
19,
20,
21,
22,
23].
The successful implementation of external intervention policies is lacking for rural households coping with health shocks. The current intervention policies have various problems that need to be resolved. Firstly, how can groups suffering from health shocks be accurately identified? The loss of targeting efficiency due to information asymmetry is a longstanding problem in aid programs, which is also unsolved in several developing countries. This problem causes a mismatch between relief resources and the needs of rural households, and it lowers the effectiveness of external intervention policies [
8,
24]. How, then, can the human capital of rural households suffering from health shocks be improved? Health shocks often lead to a loss of labor days or lowered productivity both for patients and their caregivers. Moreover, health shocks may lead certain laborers to permanently quit the labor market [
14]. Thus, it is crucial to improve the level of human capital and enhance the resilience of household laborers. To achieve this aim, most existing studies have noted that it is necessary for the government to build a formal social protection system [
18,
19,
25] to cushion rural households from health shocks. However, the social protection system can only reduce the economic burden of health shocks and has limited effects on improving the human capital of rural households. It cannot truly enhance the ability of rural households to cope with health shocks [
26]. Finally, how can sustainability increase the long-term household income of those suffering from health shocks? Health shocks directly incur not only a sizable out-of-pocket medical expense but also a long-term economic loss [
12,
27,
28]. Some studies have reported the positive long-term effects of credit and insurance on rural households coping with health shocks [
12,
16,
17,
28]. However, a high mortgage threshold limits credit availability [
29]. Meanwhile, social insurance is also inaccessible in many developing countries [
27,
30]. Therefore, effective, universal and inclusive policies are still needed to improve the household income of groups suffering from health shocks in the long term. In other words, to actually enhance the resilience of rural households in the face of health shocks, these three problems need to be resolved through external intervention policies.
China has long been plagued by poverty at a scale and level of severity that has rarely been seen anywhere else in the world [
31]. According to data released by the World Bank, until 2012 there were 897 million people living on less than 1.9 USD per day in the world, among whom 87 million people were living in China. Meanwhile, poverty caused by health shocks has always been the greatest problem for China’s poverty alleviation efforts. The Poverty Alleviation Office of the State Council of China claimed that illness caused 42.3% of poor rural households in the registered poor rural household database to slip into poverty or slip back into poverty in 2017 [
11]. To accelerate progress towards extreme poverty reduction, China launched the Targeted Poverty Alleviation program in 2013, which contained a series of policies and made China the first developing country to eradicate extreme poverty [
9,
31,
32]. The policy package of the Chinese government is an integrated system that contains more than three types of external intervention policies, namely, monitoring nets, safety nets and cargo nets, which may provide insights into solving the longstanding problem of health-related poverty alleviation. Concretely, monitoring nets are composed of village-based assistance systems and poverty alleviation coordinator systems, which may address the problem of information asymmetry in aid programs [
8]. Safety nets include subsistence allowances, transfer income, the renovation of rural dilapidated houses and other measures, which may improve the economic performance of poor rural households in a short period of time. Additionally, cargo nets include vocational training, microcredit, relocation, etc., which may effectively enhance the ability of poor rural households’ human capital to cope with health shocks and increase their household income in the long run. However, although China’s Targeted Poverty Alleviation program has made progress in mitigating the adverse effects of health shocks on the livelihoods of poor rural households, few studies have comprehensively explored the underlying mechanisms. In practice, existing studies have considered only the relationships between health poverty alleviation projects and the economic vulnerability of poor families [
33,
34], failing to fully reflect the efforts made by the Chinese government to address poverty-related health shocks. Therefore, to explore a successful case of external intervention policies, it is necessary to research the topic in China.
To fill the gap in research noted above, based on China’s Targeted Poverty Alleviation program, this paper attempts to empirically explore whether the monitoring nets, safety nets and cargo nets mentioned above play roles in poor rural households coping with health shocks. The specific objectives of this paper are as follows: (1) to summarize the policy roles of China’s Targeted Poverty Alleviation program in the ability of poor rural households to cope with health shocks; (2) to examine how monitoring nets accurately identify poor rural households suffering from health shocks; and (3) to reveal the mechanisms through which government support policies enhance the human capital of poor rural households coping with health shocks. If the effects of Chinese government support policies on mitigating the health shocks of poor rural households are verified, then these findings can shed light on the design and implementation of policies that aim to eradicate poverty related to disease in low- and middle-income countries.
The paper is structured as follows:
Section 2 outlines the Chinese policy context and elaborates on the relationships between human capital, the Targeted Poverty Alleviation program, and health shocks.
Section 3 lays out the choice of the field sites and methods of data collection.
Section 4 and
Section 5 present the research design and the results, respectively.
Section 6 discusses the main core results. Finally,
Section 7 concludes with policy implications.
4. Econometric Methodology
To examine the relationships between health shocks and poor rural households’ income, human capital and policy support and the effectiveness of support policies in prompting an income increase for poor rural households, multiple regression analysis and hierarchical regression are employed. In these regression analyses, dependent variables and independent variables are needed, and they are explained in detail in the next section.
4.1. Dependent Variables
Three dependent variables are selected, namely, income, identification of the poor and duration of poverty.
Income is the first dependent variable. When rural households suffer from health shocks, the number of their household laborers and their effective working time decrease, which will affect their household income [
15]. Rural household income is sensitive to health shocks. Given that poverty alleviation means that the welfare of the entire population is protected, per capita household income [
55] is chosen to represent the state of household income.
Identification of the poor refers to the year that a rural household is identified by the government as a poor rural household. As mentioned in
Section 2, monitoring nets are formed by village-based assistance and grid supervision in rural China. Once rural households suffer from health shocks, the monitoring nets identify them in a timely manner to prevent them from slipping too far into poverty and to keep them above the poverty line. Thus, identification of the poor is employed to examine the effectiveness of the monitoring nets.
Duration of poverty refers to the length of the period during which rural households are identified as poor. The duration of poverty among poor households varies by the different causes of poverty. This variable is selected to measure whether health shocks extend the duration of poverty among poor rural households. It is expected that the Targeted Poverty Alleviation policies are effective when the duration of poverty is not prolonged by health shocks.
4.2. Independent Variables
The independent variables are selected to describe the health shocks, human capital and policy aspects.
Health shocks are the first independent variable. In China, if a family member suffers from a chronic disease but is not hospitalized, the adverse effects are considerably smaller than those due to hospitalization [
56]. Thus, hospitalization is selected as a core variable to represent health shocks.
Human capital is the second independent variable. Human capital is not only the main source of household income but also the target of health shocks and the basis of obtaining support policies. The numbers of older people, off-farm laborers, farmers, disabled people and children in a poor rural household are selected to describe the quantity of human capital in relation to health shocks.
Policy is the third independent variable. Policies with a high penetration rate are chosen to measure the effects of policies on health shocks. All samples were covered by medical insurance, which effectively reduced short-term medical expenses. Therefore, such insurance is not considered a representation of the effects of safety nets on eliminating long-term economic loss. Thus, safety net policies mainly include the subsistence allowance system for rural areas (SA) and the renovation of rural dilapidated houses (RH). Cargo net policies include public welfare jobs (WJ), relocation (RL), industry share (IS), land transfer (LT) and microcredit (CR).
Control variables are also taken into account. Given rural infrastructure [
42], household size and housing characteristics [
13] affect the ability of rural households to cope with health shocks. In this paper, members, water and the housing structure are selected as control variables.
The details of variables mentioned above is shown in
Table 2.
4.3. Model Selection
Income, identification of the poor and duration of poverty are the main independent variables, which are multivariate variables. Based on this characteristic, multiple regression analysis is used to test the effects of health shocks on income, identification of the poor, duration of poverty and the relationship between human capital and support policy acquisition [
8,
57]. The model is presented as Equation (1). When examining the effect of health shocks on income, identification of the poor and duration of poverty,

in Equations (1) and (2), when the value and significance increase in Equation (2), human capital increases the negative effect of health shocks on poor rural households, and vice versa.
The role of support policies in per capita household income is examined by the interaction between human capital and support policies [
55,
58], which is shown in Equation (3), where y is per capita household income and

7. Conclusions and Policy Recommendations
Addressing poverty caused by disease will accelerate the process of world poverty reduction, especially in low- and middle-income countries. However, information asymmetry, human capital damage and long-term economic decline have not been resolved in health-related poverty alleviation for a long time. In practice, safety nets are common measures in poverty alleviation, but they can only partially buffer against the short-term economic burden of poor rural households and have limited effects on enhancing the long-term ability of such households to consistently withstand health shocks. Various policies are formed in China’s Targeted Poverty Alleviation program, which helps poor rural households escape from poverty traps. Thus, it is necessary to explore how China theoretically resolves the longstanding problem of health-related poverty alleviation. Based on existing paradigms in the poverty research area, this paper examines the main external intervention policies and explores how the ability of poor rural households to resist health shocks is enhanced, with the help of heterogeneous support policies and their underlying mechanisms. The data utilized in this paper were obtained from a questionnaire survey of 4635 registered poor rural households in a municipality located in Southwest China.
The results confirm that, in contrast to safety nets and cargo nets, monitoring nets formed in China’s Targeted Poverty Alleviation program can accurately link external intervention policies with poor rural households suffering from health shocks and resolve the problem of information asymmetry. Moreover, the human capital of poor rural households suffering from health shocks is enhanced by cargo nets. When poor rural households suffer from health shocks, the risk can be identified by monitoring nets in a timely manner, and then effective safety net policies and cargo net policies are offered to these households by considering the characteristics of their household human capital. Through these measures, not only can patients be supported by these policies, but their caregivers can also gain opportunities to engage in off-farm employment. Thus, the human capital of poor rural households’ ability to cope with health shocks is increased. Additionally, the long-term income increase of poor rural households is guaranteed by support policies and human capital. Human capital is linked with rural households’ access to support policies. With the support of these policies, it is possible to reverse the negative effects of dependent family members and agricultural laborers on income increase. Owing to these effective policies, poor rural households in China can successfully cope with the adverse effects of health shocks.
Based on this study, some policy recommendations can be proposed for developing countries. First, a near ex ante intervention mechanism is necessary to cope with health shocks. When poor rural households suffer from health shocks, effective external intervention is crucial for alleviating their risks. However, in a limited resource context, neither the government nor rural households can allocate a share of their resources to avert the risk of health shocks. Thus, building a near ex ante intervention mechanism is a feasible method that can both identify the risk of health shocks and rationally allocate limited resources to provide accurate supporting measures, thereby helping poor rural households to escape the negative effects of health shocks. The effectiveness of the near ex ante intervention mechanism is confirmed by the experience of the monitoring nets in China’s Targeted Poverty Alleviation practice, which can be a reference for other developing countries.
Additionally, safety nets alone are not enough to eradicate the risks of health shocks, and cargo nets based on the human capital endowment can more effectively improve the ability of poor rural households to cope with health shocks. Thus, connecting human capital with cargo nets is vital for alleviating health shocks to poor rural households. In China’s Targeted Poverty Alleviation program, by developing public welfare jobs and collective industry, public welfare jobs are provided to poor rural households that suffer from health shocks and are in danger of slipping back into poverty. Additionally, by offering microcredit, agricultural laborers receive some agricultural funding support. These cargo nets can help poor rural households to escape the adverse effects of health shocks. Therefore, building cargo net policies that can benefit vulnerable groups is an effective way to alleviate the adverse effects of health shocks.
This study has three limitations. Firstly, our survey was conducted during the implementation of China’s Targeted Poverty Alleviation program, which is highly valued by local governments. It is uncertain whether poor rural households can sustain this positive policy effectiveness as the intensity of policy implementation declines. Thus, future studies should examine the long-term policy effectiveness on the ability of poor rural households to cope with health shocks. Secondly, cross-sectional data were used in this paper, which did not make it possible to describe dynamic changes in the policy effectiveness on the ability of poor rural households to cope with health shocks over time. Answering these questions could help in better understanding policy effectiveness in different poverty alleviation stages. Finally, restricted by survey data, there is still much room for improvement in the choice of control variables. Therefore, these issues need to be explored in the future.
