Why do authoritarian regimes try to improve the quality of their governance? In the absence of democratic institutions to monitor, reward and punish their performance, authoritarian politicians are normally expected to seek their self-interest through corruption and rewards to cronies, rather than providing for the public welfare. However, the Chinese state has actively promoted improved governance in recent years, with greater attention to quality of life issues to balance the primary focus on sustaining rapid economic growth. This paper analyses intra-national variation in the provision of public goods in urban China and the impact of public goods on regime support. Does better governance lead to higher levels of public support for the regime, even in the absence of democratic elections? Our evidence suggests that it does, with a greater impact for the local level than for the centre. [ABSTRACT FROM PUBLISHER]

Using a 2011 national survey of urban residents, irrespective of their official hukou status, and the 2000–2009 night-time light data from the Defense Meteorological Satellite Program Operational Linescan System (DMSP-OLS), this paper goes beyond the simple dichotomy of migrant versus non-migrant or rural versus urban hukou to disentangle the processes of urbanization and migration and their complex associations with health, and assesses the impact of various levels and speed of urbanization on the physical and mental health of current residents in a city or town. By disaggregating urbanization into three discrete dimensions at sub-provincial levels, we find that while a higher absolute level of urbanization at the county level negatively impacted self-reported physical health, faster and accelerating urbanization had a positive impact which could be attributed to the demand-pull effect underlying the healthy migrant phenomenon. By contrast, all three dimensions of urbanization were associated with greater depressive distress and thus had an adverse effect on residents' mental health. Beyond demonstrating how variation in the process and location of urbanization affects individual health, we also illustrate more broadly the value of modelling locational parameters in analyses of individual outcomes based on national samples.

We argue that interjurisdiction competition in authoritarian regimes engenders a specific logic for taxation. Promotion-seeking local officials are incentivized to signal loyalty and competence to their principals through tangible fiscal revenues. The greater the number of officials accountable to the same principal, the more intense political competition is, resulting in higher taxation; however, too many officials accountable to the same principal leads to lower taxation due to shirking by uncompetitive officials and the fear of political instability. Using a panel dataset of all Chinese county-level jurisdictions from 1999–2006, we find strong evidence for an inverse U-shaped relationship between the number of county-level jurisdictions within a prefecture—our proxy for the intensity of political competition—and fiscal revenues in most provinces but not so in politically unstable ethnic minority regions. The results are robust to various alternative specifications, including models that account for heterogeneous county characteristics and spatial interdependence. [ABSTRACT FROM PUBLISHER]

Village elections in China present scholars with the case of a single-party regime that allows voters to reject candidates regularly. Using a micro survey of 698 voters in 30 rural election districts, the authors demonstrate that when some candidates can lose, voters participate. A comparison of models of voter turnout and running for office further demonstrates that even when competition is structured to the benefit of party members, the perception of competition as choice between candidates is sufficient to engage voters and increase their perception that the electoral process is fair. These findings hold regardless of a respondent's age, gender, membership in the Communist Party and Youth League, and general knowledge level and access to media. Village wealth and geographical isolation also do not demonstrate a strong substantive impact. One theoretical implication of these findings is that contested elections in authoritarian regimes may simultaneously strengthen demand for accountability and loyalty to the regime.

List-based samples are often biased because of coverage errors. The problem is especially acute in societies where the level of internal migration is high and where record keeping on the population is not reliable. We propose a solution based on spatial sampling that overcomes the inability to reach migrants in traditional area samples based on household lists. A comparison between a traditional study and our sample of Beijing demonstrates that coverage bias is greatly reduced. The successful incorporation of mobile urban residents has important substantive effects, in both univariate and multivariate analyses of public opinion data. [ABSTRACT FROM AUTHOR]

Abstract: China''s rapid economic growth has had a serious impact on the environment. Environmental hazards are major sources of health risk factors. The migration of over 200 million people to heavily polluted urban areas is likely to be significantly detrimental to health. Based on data from the 2009 national household survey “Chinese Attitudes toward Inequality and Distributive Injustice” (N = 2866) and various county-level and municipal indicators, we investigate the disparities in subjective exposure to environmental hazards and associated health outcomes in China. This study focuses particularly on migration-residency status and county-level socio-economic development. We employ multiple regressions that account for the complex multi-stage survey design to assess the associations between perceived environmental hazards and individual and county-level indicators and between perceived environmental hazards and health outcomes, controlling for physical and social environments at multiple levels. We find that perceived environmental hazards are associated with county-level industrialization and economic development: respondents living in more industrialized counties report greater exposure to environmental hazards. Rural-to-urban migrants are exposed to more water pollution and a higher measure of overall environmental hazard. Perceived environmental risk factors severely affect the physical and mental health of the respondents. The negative effects of perceived overall environmental hazard on physical health are more detrimental for rural-to-urban migrants than for urban residents. The research findings call for restructuring the household registration system in order to equalize access to public services and mitigate adverse environmental health effects, particularly among the migrant population.

Male infertility is a major concern affecting human reproductive health. Asthenoteratospermia can cause male infertility through reduced motility and abnormal morphology of spermatozoa. Several genes, including DNAH1 and some CFAP family members, are involved in multiple morphological abnormalities of the sperm flagella (MMAF). However, these known genes only account for approximately 60% of human MMAF cases. Here, we conducted further genetic analyses by using whole-exome sequencing in a cohort of 65 Han Chinese men with MMAF. Intriguingly, bi-allelic mutations of TTC21A (tetratricopeptide repeat domain 21A) were identified in three (5%) unrelated, MMAF-affected men, including two with homozygous stop-gain mutations and one with compound heterozygous mutations of TTC21A. Notably, these men consistently presented with MMAF and additional abnormalities of sperm head-tail conjunction. Furthermore, a homozygous TTC21A splicing mutation was identified in two Tunisian cases from an independent MMAF cohort. TTC21A is preferentially expressed in the testis and encodes an intraflagellar transport (IFT)-associated protein that possesses several tetratricopeptide repeat domains that perform functions crucial for ciliary function. To further investigate the potential roles of TTC21A in spermatogenesis, we generated Ttc21a mutant mice by using CRISPR-Cas9 technology and revealed sperm structural defects of the flagella and the connecting piece. Our consistent observations across human populations and in the mouse model strongly support the notion that bi-allelic mutations in TTC21A can induce asthenoteratospermia with defects of the sperm flagella and head-tail conjunction., (Copyright © 2019 American Society of Human Genetics.
