Haze pollution is one of the most concerned environmental issue, it is of great significance to control haze pollution without affecting economic development. Using the panel data composed of PM2.5 concentration and other data from 278 cities in China between 2003 to 2016, this paper empirically investigates the impact of urban innovation on haze pollution and its transmission mechanism. Based on the fixed effect model, the research finds that the increase of urban innovation significantly reduced haze pollution. The result still holds after dealing with possible endogenous problems. Energy consumption and industrial agglomeration are two important transmission channels through which urban innovation affects haze pollution. Furthermore, time heterogeneity analysis shows that the negative effect of urban innovation on haze pollution increases with time. Spatial heterogeneity analysis shows that urban innovation has a greater mitigation effect on haze pollution in eastern cities than in central and western cities in China. This paper indicates that technological innovation as the main driving force for development, can provide strong support for China to achieve the aims of improving the ecological environment.

Using data from China Family Panel Studies in 2012, this paper investigates the impact of kinship networks on participation in the New Rural Pension Plan (NRPP) in China. The theoretical model and empirical results indicate that kinship networks can provide informal social security, such as psychological security and financial transfers from relatives. Thus, people who are part of stronger kinship networks are less likely to participate in the NRPP than their counterparts. Our research facilitates an understanding of the interaction between social networks and formal institutions and provides policy implications for an aging China.
