摘　　要：本文基于2003-2012年我国各地区的面板数据,综合采用非参数Kernel密度估计方法、门槛面板模型考察出口贸易与工业环境技术效率的动态演进特征和非线性关系。研究结果显示:运用非角度、非径向的DEA-SBM模型估算的我国30个省市区的工业环境技术效率普遍偏低,东部地区的工业环境技术效率显著高于中、西部和东北地区;通过核密度曲线观察到我国工业环境技术效率呈现持久的双峰分布,而出口贸易水平整体上处于上升态势;进一步采用门槛面板模型分析,发现出口贸易对我国工业环境技术效率产生的影响存在显著的门槛特征,即出口贸易对工业环境技术效率的影响随着经济发展水平的提高而显著增强,随着工业企业规模的扩大而减弱。The paper comprehensively uses the kemel density estimation and threshold panel model to analyze the dynamic characteristics and nonlinear rela- tionship between the export trade and the technical efficiency of industrial environ- ment based on the provincial panel data during 2003 - 2012. The results show that the average level of the technical efficiency of industrial environment is relatively low. The paper also finds that the technical efficien- cy of industrial environment of the eastern region is substantially higher in com- parison to the western, northeastern and central regions. The evolution of kernel density curves shows that the technical efficiency of the industrial environment has two peaks, with the export trade on the rise on the whole. Further, the ex- port trade of China exerts influences with threshold characteristics on the techni- cal efficiency of industrial environment, meaning that the effect of export trade on the technical efficiency of industrial environment significantly enhances along with the rising of economic development, and is weakened with the scale expan- sion of the industrial enterprise.
