摘要
从财政分权视角切入,使用动态固定效应和门槛模型分析了财政分权与人口集聚、产业结构、科技创新投入、经济发展水平和生产技术进步的关联效应对环境污染异质性的影响。主要结论:(1)财政分权对环境污染的影响效果存在异质性,与具有单向外溢性质的水污染呈倒"U"型曲线关系,与具有双向外溢性的大气污染呈"U"型曲线关系;(2)财政分权对工业废水排放量影响的两个门槛值为0.4506和0.6471,对工业二氧化硫排放量的门槛值为0.5275和0.7609;(3)外资利用、经济发展和财政分权的门槛效应会改变"U"型曲线的"拐点值"位置,并且在这三种门槛条件下,财政分权与其他环境污染主要影响因素的关联效应对各污染物的作用方向不同,揭示了其与环境污染非线性关系的实质。
Use dynamic fixation and threshold models analyze the impact of fiscal decentralization on the heterogeneity of environmental pollution. The main conclusions are:( 1) the effect of fiscal decentralization on environmental pollution is heterogeneous,fiscal decentralization and the one-way spillover water pollution are inverted " U" curve relationship,and with two-way spillage of air pollution is " U" curve relationship;( 2) the two thresholds for fiscal decentralization impact on industrial wastewater emissions are 0. 4506 and 0. 6471,and the threshold for industrial sulfur dioxide emissions is 0. 5275 and 0. 7609;( 3) the threshold effect of foreign capital utilization,economic development and fiscal decentralization will change the " inflection point value" position of the " U".
