本文基于不完全契约理论和Antweiler et al 。（2001）的研究框架，构建企业排污的一般模型，采用“差异中差异”的估计方法，结合我国省际制造业细分行业数据，考察契约制度对环境质量的影响。研究结果表明，地区契约制度是影响环境质量的重要因素，在契约制度较为完善的地区，企业倾向于投入“减排专用资本”进行污染减排活动，进而改善环境质量。但这种积极作用在契约密集度较高的行业并没有得到进一步强化，利用行业本身的污染强度属性则可以解释这一“反常”的结果。在控制人均资本存量、人力资本、外商直接投资和对外贸易等因素后，研究结论依然稳健。

Based on the the incomplete contract theory and the research framework of Antweiler et al .（ 2001 ） , this pa-per develops a general model of pollution discharge , and then uses the Difference-in-Difference method with data of two-digit manufacturing industries of China to examine the impact of the contract institution on the environmental quality .The empirical result shows that contract institution is a key factor influencing pollution discharge .Moreover , firms are apt to invest “special emission reduction capital” to reduce pollution and improve environment quality in the regions where contract institution is comparatively sophisticated .However, this positive effect fails to be strengthened in those industried with higher contract in -tensity, which can be explained by the pollution intensity of the industry itself .The research result remains stable after control-ling a series of factors such as per capita capital , human resources , foreign direct investment and foreign trade.
