摘要 本文基于我国2004-2011年工业33个细分行业的面板数据实证考察了环境规制对贸易自由化的门槛效应。实证结果表明:在R&D双环节效率门槛条件下,环境规制对贸易自由化都存在倒"U"型作用机制,即在R&D双环节效率达到拐点前,环境规制的创新补偿作用推动了产业贸易竞争优势的提升,进而促进了贸易自由化进程,而达到拐点后,环境规制带来的生产成本上升的负向溢出效应显现。从行业分类特点考察环境规制对贸易自由化的影响,发现大多行业的环境规制较多地抑制了贸易自由化水平的提升,环境规制的创新补偿优势并不明显。同时,考察了其他因素对贸易自由化的影响,指出行业规模化水平是促进贸易自由化的积极因素,而工资水平、产业结构等则是不利因素。 Based on panel data of 33 industrial sub-sectors from 2004 to 2011, this paper examines the threshold effect of environmental regulation on trade liberalization. The empirical results show that under the threshold conditions of R&D dual-link efficiency, there is an inverted U-shaped influencing mecha- nism of environmental regulation on trade liberalization, testifying to the "Porter Hypothesis" that under certain conditions, before the R&D dual-link efficiency reaches the "inflection point", the innovation compensation effect of environ- mental regulation enhances the trade competitiveness of the industry, thus contrib- uting to trade liberalization; when the turning point is reached, however, the nega- tive spillover effects appear due to rising production costs caused by environmen- tal regulation. Furthermore, when surveying the effect of environmental regulation on trade liberalization from the perspective of industrial classification, we find that for most of the industries, environmental regulation restricts the deepening of trade liberalization, and the innovation compensation advantage of environmental regulation is too moderate. Meanwhile, we investigate the effects of other factors on trade liberalization, finding out that industrial scale level is a positive factor promoting trade liberalization, while wage level and industrial structure are unfa- vorable factors. This study urges that initiatives be taken to optimize the industri- al structure in China.
