摘　　要：运用中国内地31个地区1997-2017年面板数据进行空间计量回归,以专利数量为创新衡量指标,得到进口对创新的回归结果,发现进口对本地和邻里地区创新均有显著正向影响。从系数量值看,邻里效应远大于本地效应,表明邻里效应更加重要。研发人员数量和物质资本存量邻里效应显著为负,表明地区间在创新生产要素上存在竞争关系。使用不同核算方法下的物质资本存量数据进行稳健性检验,确认回归结果的稳健性。提出在当前逆全球化背景下“双循环”新阶段,中国仍要坚定地扩大各类产品进口,地方政府在扩大进口的同时需要加强人才和资本引进力度。This paper dose spatial regression based on panel data of 1997-2017 with 31 regions of Chinese mainland.Taking the number of patents as the index of innovation,we get the regression results of import to innovation.It is found that import has a significant positive effect on local and neighborhood regions.According comparation of the values of coefficients,we find that the neighborhood effect is far greater than that of local effect.The importance of neighborhood effect is confirmed.The number of R&D persons and the stock of physical capital have significantly negative neighborhood effects.It indicates the competitive relationship between regions on innovative production factors.Then,we use different data of capital to test the robustness of the regression results.Policy suggestion is that in the"double cycle"stage,under the background of counter-globalization,China still needs to expand the import of various products firmly.Suggestions to local governments is to strengthen introduction of talents and capital while expanding the import,because that they are competitors on the introduction of innovative production factors.

关 键 词：进口 创新 本地效应 邻里效应 区域竞争
