Project description:The sustainable development of pension systems has been investigated from a financial perspective worldwide. However, the pension adequacy and its effect on the sustainability of a national pension system are still understudied. Using actual replacement rate and modified living standards replacement rate, this study empirically evaluates whether China's New Rural Pension Scheme (NRPS) grants enough livelihood protection for the rural residents in the Northwestern China. The results show that the NRPS fails to meet the basic needs of the elderly people (i.e., age of sixty years or older) or the middle-aged people (forty-five to fifty-nine years old), while it only provides limited protection for the young people (sixteen to forty-four years old). These findings suggest that the current NRPS benefits are very low in the Northwestern China and policy reforms should be further implemented to improve the sustainable development of the New Rural Pension Scheme.
Project description:Based on the data from the China Family Panel Studies (CFPS) in 2018, the relationship between internet use and informal workers' wages and its internal mechanism were empirically discussed using the ordinary least squares and endogenous switching regression(ESR) model. The study found that internet use could significantly raise the level of wages of informal workers, and this conclusion still holds after the endogenous problem was solved through the endogenous switching regression model. Further research found that the influences of the internet use on informal workers' wages was heterogeneous. In other words, internet use has a more obvious impact on the wages of informal workers aged 31 to 40, 41 to 50, and 51 to 60 with the educational level of university and above in cities and towns, while it has a significant negative impact on wages of informal workers aged 16 to 20.
Project description:Studies have shown that political participation does not only affect the flow of public resources but also creates positive feedback on participants’ subjective perceptions. However, research on the relationship between political participation and the life satisfaction of Chinese urban residents is relatively scarce. Thus, this study investigates whether political participation helps improve the life satisfaction of Chinese urban residents. Based on 2577 samples of the 2015 Chinese Social Survey this study used the Ordinary least squares model, instrumental variable model, and propensity score matching model to explore the relationship between political participation and the life satisfaction of Chinese urban residents. The empirical results show that political participation can significantly improve the life satisfaction of urban residents. Compared with urban residents without political participation, the life satisfaction of the political participants was 0.145 units higher at a 0.05 level of significance. In addition, this improved effect varied in degree among different groups of urban residents and was more significant for females, members of the Communist Party of China, highly educated, and employed urban residents. In China, there is a significant relationship between political participation and the life satisfaction of urban residents, with the life satisfaction of urban residents improving significantly through political participation. There are differences in the level of this improved effect among different urban residents, and it is more significant for females, highly educated, members of the Communist Party, and employed urban residents. To improve the life satisfaction of Chinese urban residents, it is necessary to further broaden their political participation channels.
Project description:Despite growing attention to Internet activity as a social determinant of depression in adolescents, few studies have focused on its diverse effects on depressive symptoms. Using data from the 2020 China Family Panel Study, this study employed logistic regression analysis to examine how Internet activity affects depressive symptoms in adolescents in China. The results indicated that adolescents with longer online duration using mobile phones tended to have higher levels of depression. Adolescents who engaged in online activities related to games, shopping, and entertainment had more severe depressive symptoms, but their time spent on online learning was not significantly associated with their level of depression. These findings suggest a dynamic link between Internet activity and adolescent depression and offer policy implications for addressing depressive symptoms in adolescents. Specifically, Internet and youth development policies and public health programs during the COVID-19 pandemic should be designed based on a comprehensive account of all aspects of Internet activity.
Project description:Full employment is important to promote the high-quality development of the urban economy. Using urban-level data on China from 2004 to 2018, we analyse the effects and mechanism of expanding imports on urban manufacturing employment. We use the Guiding Opinions on Strengthening Import to Promote Balanced Development of Foreign Trade issued by the China State Council in 2012 as a natural experiment to solve the endogeneity problem. We find that expanding imports significantly increases urban manufacturing employment. This conclusion is still robust after a series of robustness tests. Further mechanism tests reveal that productivity improvements and upgrades to product quality from expanding imports can explain increased urban manufacturing employment. The results of the heterogeneity analysis show that expanding imports promote manufacturing employment in large and medium-sized cities but not small cities. Expanding imports increases employment in manufacturing in cities in different regions, with the largest effects on eastern cities, the second largest effects on western cities, and the smallest effects on central cities. These results suggest that expanding imports is an effective channel for increasing employment.
Project description:IntroductionDepression has become one of the most prevalent mental illnesses affecting the elderly in aging countries, i. e., in countries of the world whose population is slowly aging. It has become an important topic for scientists and policymakers to analyze how best to improve the elderly's mental health and save them from depression. The aim of this paper was to investigate whether and to what extent internet use may affect depression in the elderly. The heterogeneous effects of internet use on the elderly's depression across age, gender, and occupation were also investigated.MethodsThe data used in the present study were gathered from the China Health and Retirement Longitudinal Study that was conducted in 2018. The propensity score matching technique and the endogenous switch regression model were employed in this study to address potential endogeneity caused by both observed and unobserved factors.ResultsThe results of the present study show that the elderly who are relatively young, male, well educated, live in an urban area, or have a small family are more likely to use the internet. The elderly who have healthy eyes or good eyesight, those who are not employed in the agricultural sector, or those who are retired, and those who are not eligible to receive any subsistence allowance or drink wine have a higher probability of using the internet. We also find that internet use significantly reduces the elderly's depression status by 3.370 points, which is roughly equivalent to a reduction of 37.19%. Heterogeneity analysis on internet use reveals that the health effect is particularly effective for agricultural workers, female, or the older elderly.ConclusionThe results of the present study highlight the significant welfare effects brought about by the development of internet infrastructure. To improve the mental health of the elderly, the government should encourage them to adopt the internet. In particular, the needs of the elderly who are older, female, or have agricultural work should be paid more attention to motivate them to use the internet more to alleviate depression.
Project description:Although rapid urbanization is often considered as one of the most important drivers for changing dietary patterns, little attention has been paid to rural areas despite the profound transformation they have undergone. Using longitudinal data from the China Health and Nutrition Survey (CHNS) for the period from 2004 to 2011, this study seeks to better understand the relationship between the urbanization of rural areas and dietary transition, with the focus on nutrition intake and dietary quality. Our results suggest that with increasing urbanization, rural residents tend to have on average lower calorie intakes but higher dietary quality. Specifically, increasing urbanization consistently reduces carbohydrate consumption and reduces fat consumption after a turning point; protein consumption first decreases and then increases after the turning point with increasing urbanization. Urbanization shows a significant and positive effect on the Healthy Eating Index (HEI). In addition to sociodemographic changes, we find that changing consumer preferences and knowledge serve as important determinants in explaining the dietary transition in rural China from 2004 to 2011. In our study, urbanization appears to positively affect rural residents' healthy food preferences and dietary knowledge. This study is a first attempt for better understanding the nutrition transition resulting from accelerating urbanization in rural China; several limitations and areas for future research have been highlighted.
Project description:Digital transformation plays a crucial role in improving the quality development of companies in this era of digital economy with ever-changing technologies. This paper empirically investigates the impact of corporate digital transformation on total factor productivity and the mechanism of action, using A-share listed companies in Shanghai and Shenzhen from 2011-2021 as the research sample, and found that the digital transformation of companies significantly improves total factor productivity, with the plausibility of the findings being verified by a series of robustness tests. Based on the heterogeneity study, it is found that such effect is stronger for private companies, non-high-tech companies, and companies with a high degree of industry competition. The mechanism test indicates that digital transformation facilitates total factor productivity through four ways: strengthening company technological innovation, reducing operational costs, increasing resource allocation efficiency, and improving human capital structure. The findings of this paper support a better understanding of the micro effects of digital transformation and provide empirical evidence for policy formulation and adjustment.
Project description:Background and objectivesSelf-employment is a vital alternative to waged employment for older workers. Recent research has shown that employment transitions frequently occur when individuals approach retirement. However, evidence of how older people's health changes when they switch between self and waged employment is lacking, particularly outside Western contexts. To address this research gap, we explored the health impact of employment transitions for the older working population in China by hukou (urban or rural household registration status), region, and education.Research design and methodsWe employed fixed effect models to examine the impact of employment transitions on cognitive, mental, and physical health and life satisfaction drawing on data from four waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (N = 4,606). Given China's unique context, we analyzed the results of agricultural and nonagricultural work separately.ResultsIndividuals transitioning into or remaining in self-employment had lower self-rated health and life satisfaction than those remaining in waged employment. There was no significant difference in cognitive functioning or depressive symptoms. Additionally, those who transitioned from self-employment into waged employment rated their health worse than those who remained in waged employment. The health impacts were more apparent for agricultural than nonagricultural self-employment, particularly for older workers living in urban regions with rural hukou and lower education levels.Discussion and implicationsMost older Chinese transitioning into or staying self-employed are or were pushed into self-employment due to their low human capital and socioeconomic status, which affects their subsequent health. Pension reform and policies supporting older adults to stay in the workforce could help close the economic and health gaps between rural and urban older adults.
