环境污染对工业企规模影响 的库兹涅茨特征分析

Abstract

本文利用2004-2008年全国工业数据库面板数据，关注环境污染和规制条件下企业规模的决策行为，同时关注环境污染和规制下的外国独资企业、国有控股企业的的职工数的战略决策的差异性。本文以Copeland (1994)中提出的"污染天堂"假说作为理论基础，并试图使用其验证在不同所有制企业中的差异性。回归模型中设置企业职工数为被解释变量，体现企业规模的战略决策，利用OLS回归和面板数据的个体固定效应模型回归进行实证研究。回归结果显示，第一，克服了时间序列分析受多重共线性的困扰的问题后，空气污染对企业职工数的规模战略的影响都变成不显著影响；第二，环境规制对外国独资企业的规模战略决策的影响存在显著的U型影响，对国有控股企业的规模战略决策的影响存在显著的EKC效应。 This paper documents and discusses properties of business strategy decisions under pollution conditions. All empirical work is based on the theory developed by Copeland (1994), formally called "Pollution Paradise". In fixed-effect panel data regression model, we set "Number of Employees" which indicates corporate decision-making behaviors, as the explained variables and set "Polluted Air", which all can be treated as measure of pollution, to be the explainable covariates. The results illustrate that on the average level: Firstly, after overcoming the multi-collinearity problem, effects of air pollution on the number of enterprise employees scale strategy have become no significant; Secondly, for foreign-owned enterprises, the influence of environmental regulation on the decision scale strategy have a significant "U" effect. However, for state-owned enterprises, the effect of environmental regulation on the decision scale strategy have a significant "EKC" effect.
