通过对无法观测的非物化型隐性知识这一具有空间扩散属性的遗漏变量用空间向量自回归式予以表达,文章将传统线性的国际研发知识溢出检验模型扩展成为具有空间Durbin结构的非线性模型,以测度非物化型隐性知识对东道国进口地的局域溢出效应以及对进口地以外其他地区的跨区域溢出效应。基于中国样本的检验结果显示:非物化型隐性知识的局域溢出与跨区域溢出表现出强烈反差,局域溢出并不显著;其中服务贸易非物化型隐性知识的跨区域溢出效应最大也最为稳健,外商直接投资次之,货物贸易最弱。由此提示需扩大内陆地区对外开放、分清不同外贸方式的主次顺序以及优化服务贸易结构。
Through the omission of unmeasured tacit knowledge of tacit knowledge, which is a spatially diffusive variable, we use space vector autoregression to express the traditional linear international R & D knowledge spillover test model into a nonlinear model with space Durbin structure To measure the spillover effects of tacit knowledge of tacit knowledge on the host country’s imports and the cross-regional spillover effects on other regions outside the region of import. The test results based on the Chinese sample show that the spillovers of non-materialized tacit knowledge show a strong contrast with the trans-regional spillover, and the spillovers are not significant. The cross-regional spillover effect of the non-materialized tacit knowledge is also largest The most stable, followed by foreign direct investment, the weakest trade in goods. This suggests that it is necessary to expand opening up to the outside world, clarify the order of major and minor differences in different modes of foreign trade, and optimize the structure of trade in services.
