使用1999~2009年中国工业企业的数据,基于企业产品创新的视角,综合运用生存分析方法和回归分析方法研究技术创新对出口增长集约边际的影响。结果表明:技术创新对工业企业出口持续时间和出口绩效都有正向而显著的影响。将工业企业划分为高新技术和非高新技术企业后发现,专利对非高新企业出口持续时间有正而显著的影响,而新产品产值则对高新企业出口持续时间有正向而显著的影响。专利对高新企业和非高新企业出口绩效都有正向的影响,而新产品产值仅对非高新企业出口绩效有正向而显著的影响。最后实证检验了分地区和分所有制类型工业企业技术创新对出口持续时间和出口绩效的影响。
Based on the data of Chinese industrial enterprises from 1999 to 2009 and based on the product innovation of enterprises, the author uses the methods of survival analysis and regression analysis to study the impact of technological innovation on the intensive marginal growth of export. The results show that technological innovation has a positive and significant impact on the export duration and export performance of industrial enterprises. After dividing industrial enterprises into high-tech and non-high-tech enterprises, it is found that patents have a positive and significant impact on the export duration of non-high-tech enterprises while the output value of new products has a positive and significant impact on the export duration of high-tech enterprises. Patents exert a positive influence on the export performance of high-tech enterprises and non-high-tech enterprises, while the output value of new products has a positive and significant impact on the export performance of non-HNTEEs only. At last, the paper empirically tests the influence of technology innovation of sub-ownership and sub-ownership industrial enterprises on export duration and export performance.
