| Summary/Abstract |
Environmental issues, especially air pollution, have attracted much attention with the development of economy in China. In order to provide a new idea for how to perfect the mechanism of regional joint prevention and control of air pollution, this paper empirically estimates the spatial spillover effect of industrial agglomeration on haze pollution. The results show that the haze pollution has a significant positive correlation with the industrial agglomeration levels in local and neighboring regions. Direct and indirect effects of the industrial agglomeration are all significantly positive, and the latter are much higher than the former. It indicates that the haze pollution is not only affected by the industrial agglomeration in the local region, but also neighboring regions. Furthermore, we find that the direct and indirect effects in central and western China exceed those in eastern China. In addition, the direct and indirect effects of industrial agglomeration in heavily polluting industry are higher compared with non-heavily polluting industry.

| Summary/Abstract |
This paper reports the innovation effect of pharmaceutical industry agglomeration from the perspective of patterns of agglomeration and innovation, by using registration application data for innovative and generic drugs as indicators of pharmaceutical innovation. First, the distribution of the pharmaceutical industry in China is characterized by high agglomeration and low innovation. Second, no significant influence is exerted by regional industrial and development zone agglomeration on the development of innovative drugs in different regions; the effect of the promotion of generic drugs is reflected mainly in the location entropy index. Third, the existence of a crowding effect weakens the effect of the promotion of agglomeration on pharmaceutical innovation and the adverse impact on innovative drugs is significantly greater than the effect on generic drugs. In further research, we explored the bias effect of agglomeration in development zones and the synergistic effects of different agglomeration models. It is difficult to improve the quality of independent innovation by spatial agglomeration. Government-led development zones play a rather limited role in pharmaceutical innovation.
