摘要
企业出口对环境污染的影响尚缺乏严谨的因果识别和发展中国家的直接证据。本文利用1998—2007年中国微观企业污染排放和工业企业的匹配数据,选取工业废水、二氧化硫和烟尘三种典型污染物的排放强度指标对中国制造业企业出口的环境效应进行考察。为了有效缓解样本选择偏差和内生性问题,本文采用结合倾向得分匹配的双重差分法。研究表明:中国企业出口显著降低了企业污染排放强度;用出口密度近似贸易方式后,一般贸易具有显著的出口环境效应,加工贸易则并不明显。进一步的机制检验表明,通过促进绿色技术进步和减排设备投资是企业出口降低污染排放强度的重要机制。本文为既有出口贸易与环境的研究增添了来自新兴发展中大国难得的直接微观证据。
The impact of firm export on environmental pollution still lacks rigorous causal identification and direct evidence from developing countries.This paper,for the first time,used the matched data of China’s micro-firm pollution emission and production from 1998 to 2007,and selected emission intensity indicators of three typical pollutants as industrial wastewater,sulfur dioxide and smoke-dust to investigate the environmental effect of Chinese manufacturing firm export.In order to overcome the problem of sample selection bias and endogeneity,this paper adopted a difference in difference method combined with propensity score matching.Research shows that Chinese firm export significantly reduces the emission intensity;after using the export density to approximate the trade mode,it finds the ordinary trade has an obvious export environmental effect,while the processing trade is not obvious.Further mechanism tests show that promoting green technology progress and abatement investment are important mechanisms for firm export to reduce emission intensity.This paper adds rare micro-evidence from emerging large developing countries to the existing research on export and environment.
