Layout of industrial activity has always been the hot topic in research field of economic geography. With environmental problems arousing people's more and more attention and the concept of environmental economic geography being proposed in recent years, industrial layout especially pollution intensive industrial layout from the perspective of environmental regulation is of great significance. Chemical industry including petrochemical industry (hereinafter referred to as chemical industry) is not only an important basic industry sector to support economic development and national defense construction, but also the typical pollution intensive industries which are sensitive to environmental regulation. The regions along the Yangtze River (including 27 cities, from Yibin to Shanghai) are considered as the study area of this paper, where typical cities and manufacturing industry belt in China are located. Based on the chemical enterprises data and spacial measurement methods, chemical industrial spatial evolution and its influencing factors in the study area from 2000 to 2013 are discussed. The results show that the main chemical industries in the regions along the Yangtze River are located in the Yangtze River Delta especially in the regions surrounding the Taihu Lake. Chemical industry production share of urban counties was greatly reduced and that of its suburban counties along the Yangtze River was raised which reflects the suburbanization process of chemical industry from urban areas to suburbs. Main foci of enterprises are located in Shanghai and cities along the Yangtze River in Jiangsu province where enterprise hot spots are concentrated. Enterprise hot-spots in middle and upper regions along the Yangtze River developed from three regions (i.e. Wuhan urban area, Chongqing urban area and Changshou) in 2000 to more than 20 regions with different sizes including Yunxi and Dongzhi in 2010 and 2013, which are new growth poles of chemical industry. The sectors of relatively low technology dependence, low value-added products and intensive environmental pollution tend to be concentrated (e.g. fertilizer sector), whereas relatively high-end and fine sectors show a trend of diffusion (e.g. synthetic material). Chemical industrial spatial layout and evolution are affected by factors of environmental regulation, foreign direct investment and traffic location, among which environmental regulation shows significant inhibition effect on growth of chemical industry, and foreign investment and traffic location present significant promoting effect.

Key words: chemical industry, spatial pattern, influencing factors, environmental regulation, the regions along the Yangtze River
