Based on data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), this paper calculates the health distribution of the elderly using the Quality of Well-Being Scale (QWB) score, and then estimates health inequality among the elderly in rural China using the Wagstaff index (WI) and Erreygers index (EI). Following this, it compares health inequalities among the elderly in different age groups, and finally, uses the Shapley and recentered influence function-index-ordinary least squares (RIF-I-OLS) model to decompose the effect of four factors on health inequality among the elderly in rural China. The QWB score distribution shows that the health of the elderly in rural China improved with social economic development and medical reform from 2002 to 2014. However, at the same time, we were surprised to find that the health level of the 65–74 years old group has been declining steadily since 2008. This phenomenon implies that the incidence of chronic diseases is moving towards the younger elderly. The WI and EI show that there is indeed pro-rich health inequality among the rural elderly, the health inequality of the younger age groups is more serious than that of the older age groups, and the former incidence of health inequality is higher. Health inequality in the age group of 65–74 years old is higher than that in other groups, and the trend of change fluctuated downward from 2002 to 2014. Health inequality in the age group of 75–84 years old is lower than that in the group of 65–74 years old, but higher than that in the other age groups. The results of Shapley decomposition show that demographic characteristics, socioeconomic status (SES), health care access, and quality of later life contributed 0.0054, 0.0130, 0.0442, and 0.0218 to the health inequality index of the elderly, which accounted for 6.40%, 15.39%, 52.41%, and 25.80% of health inequality index. From the results of RIF-I-OLS decomposition, this paper has analyzed detailed factors’ marginal effects on health inequality from four dimensions, which indicates that the health inequality among the elderly in rural China was mainly caused by the disparity of income, medical expenses, and living arrangement.

We examined the effect of interns' learning willingness on the mentors' knowledge-sharing behavior, and examined organizational incentives and mentors' personality traits of openness and conscientiousness as moderators in this relationship. Participants were 180 mentor-intern dyads at 10 teaching hospitals in China. We found that interns' willingness to learn had a significant positive effect on the knowledge-sharing behavior of mentors. The effect of organizational incentives on this relationship was dependent on the mentor's personality, such that when mentors were low in either openness or conscientiousness, organizational incentives strengthened the relationship. Theoretical and managerial implications and directions for further research are discussed.

Air pollution is a global problem and the transportation industry is one of its major causes, yet the impact of transportation infrastructure on air quality is little understood. It is vital to know about evaluating the effects of transportation infrastructure on air quality. The urban road has a role in defining air pollution and automobiles significantly contribute to the air quality in urban areas. The issues are a result of the automobile’s impact on air quality. China put substantial investments in its metropolitan subway networks. The information on air quality on an hourly basis, daily metrological data, and demographic profiles of various cities with significant subways from the year 2013 to the year 2014 used. This study examines the effect of substantial investment on urban air quality. The Discontinuity Based Ordinary Least Squares (DB-OLS) on data for further analysis with results are incorporated in the study. The researchers witnessed a 14% reduction in air pollution during the daytime in those not rushed cities. Researchers discovered that the impacts are less severe in urban areas with a lower population density and a higher income. The results will be less dangerous if more subways affect the air quality.

The urban transit system is considered the backbone of any society as it heavily depends on economic progress. The railway transit system is crucial for any urban transit system. Based on this notion, the present research explores the industrial agglomeration in China’s prefecture-level and cities from 2010 to 2020. The research analyses the processes of urban rail transit building, industrial agglomeration, and labor agglomeration due to the railway’s transit network development. The findings are summarized in three main points; first, the agglomeration of the labor force is positively affected by the construction of urban rail transit infrastructure. Secondly, the development of railways infrastructure stimulates the agglomeration of manufacturing industries in and near urban population centers leading to the development of services industries. Third, the development and integration of railways networks with other transportation networks also optimize the allocation of capital in these areas as well. In the present research Preacher and Hayes, Behavior research methods, 2008, 40 (3), 879–891 methodology has been applied to determine the relationship between the development of railways transit system and concentration of industries, by taking into account the mediating effects of labor agglomeration. The development of railways network tends to bring economic and industrial development to these regions resulting in overall social development.

this paper studies two interrelated questions. First, has aging population brought about a great impact from a risk management point of view? Second, How to deal with the aging population brought to the risks of social security? Today we are in a risk society. As a response to the risk society, social security system itself is a means of social risk management, also faces its own risks. In the wave of aging population, how to effectively manage risks is closely related to China's social security system development and improvement. In this paper, drawing on the theory of enterprise risk management framework for social security, from the perspective of aging population challenges, our study aims to identify and classifies risks, and to make appropriate policy recommendations.
