中文摘要：

利用中国工业省际面板数据实证研究，发现市场结构和技术差距是影响企业技术溢出效应的重要因素。市场结构作用下，国有企业与“三资”企业的技术差距与技术溢出效应呈倒u型关系，而研发投入、技术人力资本和企业规模能显著提高技术溢出效应，但技术差距与技术人力资本结合未能实现技术溢出效应的扩散。此外，国有企业对“三资”企业具有正向技术溢出效应，而“三资”企业技术溢出效应有限。

英文摘要：

Using panel data from 1999 to 2013, the paper analyzes the relationship between technology gap and technology spillover theoretically and empirically. The result showsd that the impact of market structure and technology gap on technology spillover is significant. There is an inverted U curve between the technology gap and technology spillover of the state - owned enterprises and Sinn - foreign joint ventures. R＆D, technology human capital and enterprises scale have significant effect on technology spillover but the combination of the technology gap and the technology human capital does not promote the diffusion of technology spillover. Moreover, the state - owned enterprises have positive effect on the Sinn - foreign joint ventures but the Sinn - foreign joint ventures have limited impact.
