Abstract: The mode of industrial park is becoming a vital national strategy of circular economy in China and a means to enhance energy efficiency, environmental performance, and economic competitiveness. It is becoming increasingly important to control the discharge of industrial wastewater from industrial parks in order to reduce water pollution. In this paper, as taking Chengdu Xinjin chemical cluster area for example, industrial layout of the park, environmental pollution treatment measures and management situation was analyzed surrounding with water environmental issues, factors of industrial park, like layout planning, industrial structure, management mode etc. were considered as significant influence on water environment. Enterprises in the park have different discharge standards and without any supervision. The influent of the wastewater treatment plant in the park is unstable, and the total phosphorus discharge exceeds the standard for a long time, and there is no large emergency pool in the park to prepare for sudden pollution incidents. In order to solve these problems, this paper puts forward some measures, such as setting up on-line monitoring, improving the standard of enterprise water discharge, and establishing emergency command system etc. In addition, some suggestions were put forward on how to improve the industrial park water environment status and management level, to provide references for the development of industrial park. The results could have supports for the design and optimization of wastewater treatment processes, as well as for evaluation of how centralized wastewater treatment plants can help to control water pollution.

Abstract: This study examines the effect of the structure of investment in the fixed asset on provincial carbon emission in China, and investigates the channels behind this effect. Using a panel of the provincial data from 2003 to 2016, we identify the significant negative relationship between fixed asset investment of finance and local carbon emission in China. We further apply spatial econometric empirical strategy to explore the spatial effect of fixed asset investment of finance on the provincial carbon emission. Using the adjacent matrix, distance matrix and gravity matrix, it is found that the effect is similar when the spatial correlation influence is considered and to some extent, local investment in the fixed asset of financial industry may give rise to the increase of carbon emission of the surrounding provinces. Moreover, after considering the regional heterogeneity, partial evidence indicates that this negative effect only exists in the sample of eastern part provinces. Furthermore, this study also finds two channels that fixed asset investment of financial industry affects local carbon emission: financial market and the related technological innovations. Through developing financial market and improving technical innovation, the fixed asset investment of financial industry reduces the local carbon emission level. In addition, a relevant case is constructed and we found that financial fixed asset investment promotes technology transfer as well. Using relevant variables, proxies and different estimation models, the results are found robust. This paper contributes to provide a new insight into the influence of structure of fixed asset investment on carbon emission.
