(1) Background: We aim to measure the urban-rural inequality of opportunity in healthcare in China based on the theory of Equality of Opportunity (EOp). (2) Methods: Following the compensation principle, we establish a decomposition strategy for the fairness gap, which we use for the measurement of the inequality of opportunity in urban-rural healthcare utilization. We then use China Health and Nutrition Survey (CHNS) data from 1997 to 2006 to calculate the fairness gap. (3) Results: Empirical analysis using CHNS data shows that the ratio of the fairness gap to the directly observed average urban-rural difference in healthcare was 1.167 for 1997–2000 and 1.744 for 2004–2006. The average urban-rural difference observed directly from original statistical data may have underestimated the degree of this essential inequity. (4) Conclusions: Our findings suggest that upgrading urban-rural reimbursement ratios may not be sufficient in eliminating the inequality of opportunity in healthcare utilization between urban and rural residents. Within the context of an urban-rural dualistic social structure and widening of the urban-rural income gap, a shift to a pro-disadvantaged policy will be a more effective approach in promoting equality of opportunity in healthcare.

Based on the patent data from China National Intellectual Property Administration, we attempt to examine the effect of gender diversity in inventor teams on patent quality. We argue that gender diversity in inventor teams can promote patent quality, especially the invention patents that are high quality and radically innovative. Moreover, we find that the positive effect will be enhanced in places where women are well educated and improved by reducing gender discrimination. We propose that the effect will be more significant when market competition or market uncertainty is high as well as when the enterprises are private and growing. Ultimately, our study advocates that governments and enterprises should pay more attention to female labor forces, especially in the area of science and innovation, which is beneficial to improve innovation in China and eliminate gender inequality in the labor market.

Purpose: This paper theoretically and empirically analyzes the effects of the elderly’s physical health status on their need for care and the choice of care models in China.Design/methodology/approach: Empirically, the estimation results of a large-sample randomized intervention trial with chronic obstructive pulmonary disease (COPD) patients through the difference-in-difference method indicated the following: (1) After the COPD intervention trial, the physical health status of the elderly in the treatment group improved significantly, the need for care was substantially reduced and the health improvement led to a 35.5% reduction in the probability of using elderly care. (2) The reduction in the need for care regarding the treatment group occurred mainly in social care. The probability of using social care decreased by 67.8% due to the elderly’s health improvement, while that of home care remained unchanged generally. (3) Further heterogeneity tests suggested that families with fewer potential internal resources for caregiving had a more pronounced decline in the need for social care.Findings: Theoretically, these empirical results support the existence of the “pecking order” theory in the family’s choice of elderly care model, that is, families tend to employ all internal resources for caregiving before resorting to social care, resulting in a higher sensitivity of social care to health.Originality/value: The main policy implication of this paper is that ex ante preventive health intervention policies can significantly alleviate the burden of care, especially social care, on families. And preventive health intervention policies are particularly effective in reducing the burden of the families with relatively few resources for informal internal care.

The inventor is a vital input in acquiring new technologies. Collaboration among inventors is an essential topic for scholars. Talhelm et al. proposed The Rice Theory, highlighting the cultural differences between rice and wheat regions. This paper explores the differences in inventor team size under rice and wheat cultures using invention patent data in China. The results of ordinary least square estimation and instrumental variable estimation indicate that the size of inventor teams under rice culture is significantly smaller than that under wheat culture by 0.558–0.721 persons. Using the Chinese Qinling–Huaihe line, this paper constructs a regression discontinuity (RD) design. The local average treatment effect estimation confirms the difference in rice and wheat cultures. Subsequently, we demonstrate the significant existence of this difference through lots of robustness checks. We try to explain the phenomenon from the perspective of “The Rice Theory” by arguing that inventors in rice regions may be more inclined to collaborate but with a smaller inventor team size. This paper demonstrates the cultural differences in the performance of inventor team size, informing our understanding of input in research and development (R&D) activities.
