摘要
文章利用区位商指标测算制造业集聚水平。同时从技术因素角度在IPAT模型中引入产业集聚变量,通过面板回归分析得到:中国各地区制造业及21个细分行业集聚水平存在很大差异,制造业整体集聚与环境污染存在倒"N"型曲线关系,细分行业集聚则出现了倒"N"型、正"N"型、倒"U"型和正"U"型四种曲线关系。
This paper uses the location quotient index to calculate the manufacturing agglomeration level. The paper also introduces industrial agglomeration variables into IPAT model from the point of view of technical factors, and finally draws the following conclusions by panel regression analysis: there are great differences in the agglomeration level of manufacturing industry and 21 subsectors in different regions of China; the relationship between the whole agglomeration of manufacturing industry and environmental pollution takes on an inverted N-type curve, while subdivided industry agglomeration has such four types of curve relationships as N-type, inverted N-type, U-type and inverted U-type.
