本文基于2001-2013年的中国省级工业企业数据,运用面板分位数回归方法考察对外贸易对工业技术创新效率在全国、三大经济区域以及各分位点处影响效果。研究表明:运用SBM模型度量的工业技术创新效率显示东部地区处于领先地位,中、西部的追赶效应明显,且通过核密度曲线展示出双峰趋同;从全国范围来看,进口贸易对工业技术创新效率产生杠杆效应,出口贸易对工业技术创新效率则存在明显的挤出效应;三大区域中,进口贸易均产生正向溢出效应,而出口贸易对东部地区的工业技术创新效率产生杠杆效应,对中部地区则表现出挤出效应,然而对西部地区技术溢出效果要视分位点位置而定,针对分析结果提出相应的建议。
Based on the data of Chinese provincial-level industrial enterprises from 2001 to 2013, the paper uses panel quantile regression to examine the effect of foreign trade on the innovation efficiency of industrial technology in China, the three major economic regions and the sub-sites. The results show that the efficiency of industrial technology innovation measured by SBM model shows that the eastern region is in a leading position and the catching-up effect in the middle and western regions is obvious. The bimodal convergence is shown by the nuclear density curve. From a national perspective, the import trade has a great influence on industrial technological innovation Efficiency has a leverage effect and export trade has obvious crowding-out effect on the efficiency of industrial technology innovation. In all three regions, the import trade has a positive spillover effect, while the export trade has a leverage effect on the efficiency of industrial technology innovation in the eastern region. However, the technology spillover effect in the western region depends on the location of the sub-sites, and the corresponding suggestions are put forward according to the analysis results.
