摘要
在扩大进口战略和“卡脖子”背景下,本文使用2000—2013年中国工业企业数据库、国家专利数据库和中国海关进出口贸易数据库构建了核心中间产品来源地的进口多样化指标,研究其对企业创新的影响。经验研究发现:(1)核心中间产品进口来源地多样化对企业专利总数存在显著的促进作用,核心中间产品进口来源国越分散,越能促进企业创新,当其他条件不变时,核心中间产品进口来源地数量每增加1个,企业专利总数将提高0.92个百分点。(2)从机制检验的回归结果来看,进口来源地多样化通过成本下降效应和技术溢出效应两个方面显著地提升企业创新水平。(3)从异质性回归结果来看,核心中间产品进口来源地多样化对混合贸易的企业、东部地区企业、中高技术产业、从发达国家进口的企业创新激励效应更为明显。在扩大进口战略背景下,本文认为中国企业可以尽可能多样化地进行核心中间产品的全球采购,一方面可以分散“卡脖子”的风险,另一方面也可以提升企业的创新水平,推动我国经济高质量发展。
Under the current situation of import expansion strategy and“bottleneck”,this paper uses ASIF,China SIPO patent data and Chinese Custom Database from 2000 to 2013 to construct diversification index of importing core intermediate product,and studies its impact on enterprise innovation.Empirical research found that:(1)The diversification of importing core intermediate product from different source countries has a positive effect on the enterprise innovation.The more diversified the source countries of core intermediate product imports,the more it can promote enterprise innovation.When other conditions remain unchanged,the total number of enterprise patents will increase by 0.92 percentage points for each increase in the number of source countries of core intermediate product imports.(2)According to the regression results of mechanism test,import source diversification significantly improves the innovation level of enterprises through cost reduction effect and technology spillover effect.(3)According to the heterogeneity regression results,the innovation incentive effect of core intermediate product import source diversification is more obvious for mixed trade enterprises,enterprises in the eastern region,medium and high-tech industries,and enterprises importing from developed countries.Under the background of expanding import strategy,this paper argues that Chinese enterprises can diversify the global procurement of core intermediate products as much as possible,on the one hand,it can disperse the risk of bottlenecks,and on the other hand,it can also improve the innovation level of enterprises and promote the high-quality development of Chinese economy.
