Abstract:

As industrial agglomeration increases, wastewater, waste gas, and solid waste are becoming the main sources of environmental pollution. Therefore, how to correctly deal with the relationship between industrial agglomeration and pollution emissions has become a hot issue in the current academic circles. Agglomeration externality is an important mechanism to reduce industrial pollution emission, and different agglomeration modes correspond to different pollution emission behaviors. Therefore, this study divides agglomeration into four types such as specialization, diversity, related diversity, and unrelated diversity. The research goal of this paper is to investigate the effects of different agglomeration types on pollution emissions. Taking 31 provincial units in China as an example, based on the theory of agglomeration economy, this paper analyses the characteristics of industrial pollution in China and studies the relationship between industrial agglomeration and different industrial pollution. The main conclusions are as follows: (1) There is a significant spatial difference in the intensity of industrial wastewater, waste gas and solid waste. Generally speaking, the discharge intensity of industrial wastewater in the Yangtze River Basin is higher, and that of the northwest and southwest regions are rising significantly. The emission intensity of industrial waste gas and industrial solid waste in the north and northwest regions is higher. (2) Diversity is more beneficial to the reduction of emission intensity of industrial pollution than specialized agglomeration. Diversity has the greatest impact on industrial waste water, and has little effect on the gas and solid pollution. Industrial linkage is an important condition for diversity agglomeration to produce environmental 'self-purification' effect. Related diversity is conducive to the decrease of emission intensity of industrial pollution, and unrelated diversity will exacerbate pollution levels. (3) From the perspective of different polluting industries, the specialized wastewater pollution industries is conducive to the decline of pollution intensity, while the specialized waste gas and solid waste pollution industries will intensify pollution emissions. The diversified development of the polluting industry is conducive to the decline of pollution intensity. (4) The effects of different agglomeration types on industrial pollution are heterogeneous in terms of regional and pollution types. (5) To further reduce industrial pollution, we should improve the diversity of the agglomeration industry. We should also pay more attention to the improvement of the inner correlation between the industries and avoid the spatial concentration of the unrelated industries. At the same time, differentiated prevention and control measures should be formulated according to different regions, polluting industries, and industrial pollutants.
