中文摘要：

采用超越对数型随机前沿模型，在考虑企业规模、所有制结构等因素的情况下，实证分析了2004—2010年间环境规制强度对中国工业行业R＆D创新效率的影响及其行业差异。研究结果显示，我国工业行业R＆D创新效率存在显著的行业异质性；虽然，环境规制强度在一定程度上促进了工业行业R＆D创新效率提升，但环境规制强度与R＆D创新效率呈现倒“u”型关系，即环境规制强度对工业行业R＆D创新效率提升有“度”的限制，当环境规制强度超过一定水平时，反而不利于工业行业R＆D创新效率提升；环境规制强度对工业行业R＆D创新效率的影响存在显著的行业差异性，在技术密集度较高，环境污染程度较小和R＆D强度较高的行业中，环境规制对R＆D创新效率促进作用会更加显著。

英文摘要：

Based on the Tran slog stochastic frontier model, this paper makes empirical study about environmental regulation intensity＇ s affect on China industrial R＆D innovation efficiency as well as its trans - industrial difference during the years between 2004 and 2010. The result indicates that, the heterogeneity exists in China industrial R＆D innovation efficiency. Although, to a certain extent, the environmental regulation intensity promotes the industrial R＆D innovation efficiency, the inverted ＂ U＂ type relationship appears between these two sides. That is to say, the influence of environmental regulation intensity on China industrial R＆D innovation efficien- cy is relatively limited. When environmental regulation intensity exceeds a certain level, it will not be conductive to the increase of in- dustrial R＆D innovation efficiency. The influence of the former on the latter one presents the eminent industry difference. Among those industries that are technology - intensive, less polluted, with high R＆D intensity, the environmental regulation will promote the R ＆ D innovation efficiency more significantly.
