环境规制、水环境压力与经济增长---基于Tapio脱钩弹性的分解

Environmental regulation, water environmentalSpressureSand economic growth - Based on the decomposition of Tapio decoupling elasticity

摘要:

在Tapio脱钩弹性的基础上,引入工业废水排放量和工业耗水量两个中间变量,把脱钩弹性系数分解为结构效应、技术效应和规模效应,以工业废水排放量作为水环境压力指标,分析1991-2013年水环境压力与经济增长的脱钩关系。研究结果表明,脱钩弹性的技术效应和规模效应变化幅度较大,呈现出扩张负脱钩—弱脱钩-强脱钩的趋势,结构效应和综合脱钩弹性系数的变化方向基本一致,大致都呈现出强脱钩-弱脱钩—强脱钩的趋势。通过建立计量模型,以工业污染治理废水完成投资额作为环境规制指标,分析各分解效应对环境规制政策的影响程度,发现技术效应对环境规制影响不显著,结构效应和规模效应影响显著。

Abstract:

On the basis of the Tapio decoupling elasticity, introduced industrial wastewater emissions and industrial water consumption, as two intermediate variables, break down the Tapio decoupling elasticity, turn into structural effects, technical effects and scale effects, industrhe research results show that, technical effects andial wastewater emissions instead of water pressure on the environment, analysis of the relationship between water environmental pressures and economic growth from 1991 to 2013. T scale effects changed larger, showing aStrend of negative expansion decouplingS-Sweak decouplingS-Sstrong decoupling, The direction of the change ofSstructural effects and theScomprehensiveSdecoupling elasticitySis consistent, showing aStrend of strong decoupling-SSweak decoupling -Sstrong decoupling. By establishing econometric model, the completed investment to industrial pollution wastewater as theSenvironmental regulationSindex, analysis ofSthree decompositions influence of Sthe environmental regulation, findingSthe technical effects is noSsignificant, the structural effects and the scale effects is significant.
