环境管制、区域异度性与出口技术复杂度

Environmental Regulation, Regional Heterogeneity and Export Sophistication

本文基于HS大类数据,通过适当修正的Hausmann（2005）模型测算了2002~2008年中国28个省级区域出口技术复杂度。在此基础上,实证研究了环境管制对出口技术复杂度的影响,并基于区域视角进一步研究了出口技术复杂度的影响因素异质性。研究结果表明：2002~2008年间中国的环境管制不但没有削弱对外贸易的整体竞争力,而且具有促进作用,环境管制可以作为贸易结构调整的备选政策工具。本文的另一个启示是：要想提升出口复杂度以实施有限“赶超战略”,不同地区必须实行有差别的发展战略,因地制宜制定引导政策。

Based on the appropriately modified Hausmann （2005） model, this paper measures the export sophistication degrees of 28 provinces in China between 2002 and 2008 using HS 2-digit data and evaluates the effect of environmental regulation on export sophistication. Also examined is the heterogeneity of factors affecting China＇ s export sophistication from the perspective of regional heterogeneity. The empirical results show evidence of environmental regulations improving the trade structure from 2002 to 2008 instead of weakening it, indicating that environmental regulations can serve as an alternative policy instrument to adjust the trade structure. Another policy implication is that different regions must formulate different development strategies and guiding policies based on local conditions for conducting limited ＂catching-up strategies＂
