Abstract

Compared with a single pollutant, the comprehensive pollution index can reflect the degree of urban pollution more comprehensively. This article introduces the tax weighting method to calculate the comprehensive pollution index in the Yangtze River Delta (YRD). Based on the panel data of cities in the YRD from 2005 to 2017, the Spatial Durbin Model is utilized to empirically analyze the influencing factors and spatial spillover effects of the comprehensive pollution index. The results show: (1) The pollution of the cities in the YRD is unevenly distributed, and the eastern coastal areas are facing more serious pollution emissions than the western areas. (2) Changes in the urban industrial structure show an N-shaped curve impact on local industrial pollution emissions. The spatial spillover effect of the changes in industrial structure on the pollution emissions of surrounding cities presents an inverted N-shaped curve characteristic. (3) Economic openness and GDP per capita have a positive impact on pollution emissions. Government control can reduce pollution emissions. The impact of human capital and foreign direct investment on pollution emissions shows uncertainty over time and space. (4) The research results under the tax weighting method which can be proved to be applicable are consistent with the existing conclusions.

长江三角洲污染影响因素及空间溢出效应——基于一种新的测度方法

与单一污染物相比，综合污染指数能更全面地反映城市污染程度。本文介绍了用税收加权法计算长三角地区综合污染指数的方法。基于2005 - 2017年长三角城市面板数据，运用空间德宾模型对综合污染指数的影响因素和空间溢出效应进行实证分析。结果表明：①长三角各城市污染分布不均匀，东部沿海地区污染排放较西部地区严重；(2)城市产业结构变化对地方工业污染排放的影响呈n型曲线。产业结构变化对周边城市污染排放的空间溢出效应呈现倒n型曲线特征。(3)经济开放度和人均GDP对污染排放有正向影响。政府控制可以减少污染排放。人力资本和外国直接投资对污染排放的影响随时间和空间的变化呈现不确定性。(4)可以证明适用的税收加权法下的研究结果与已有的结论一致。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
