服务贸易创新发展试点政策与数字产业出口技术复杂度:理论机制与影响效应

Pilot Policies for Innovative Development of Service Trade and the Technological Complexity of Digital Industry Exports:Theoretical Mechanisms and Impact Effects

服务贸易创新发展是驱动城市出口技术复杂度升级的重要支撑。基于2010-2022年中国265个城市面板数据,文章实证检验了服务贸易创新发展试点政策对数字产业出口技术复杂度的影响效应及作用机制。研究发现:服务贸易创新发展试点政策可有效提升数字产业出口技术复杂度,且通过一系列稳健性检验。考虑城市等级与贸易形式差异,服务贸易创新发展试点政策对二线及以上城市、从事一般贸易类型的数字产业出口技术复杂度提升效果更为显著。服务贸易创新发展试点政策可通过增加数字要素投入、促进产业空间集聚、消除服务贸易壁垒等途径提升数字产业出口技术复杂度;“双轨制”知识产权保护在服务贸易创新发展试点政策对数字产业出口技术复杂度的影响中发挥正向调节效应。因此,布设全国性服务贸易创新发展网络,构筑高水平高标准数字产业集群,健全“双轨制”数字知识产权保护机制,以提升数字产业出口技术复杂度,形成数字贸易竞争新优势。

The innovative development of service trade is an important support for driving the upgrading of technological complexity of cities’exports.Based on the panel data of 265 cities in China from 2010 to 2022,this paper empirically tests the impact and themechanism of pilot policies for innovative development of service trade on the technological complexity of digital industry exports.Research has found that pilot policies for innovative development of service trade can effectively enhance the technological complexity of digital in⁃dustry exports and pass a series of robustness tests.Considering the differences in city levels and trade pat⁃terns,pilot policy for innovative development of service trade has a more significant effect on improving the technological complexity of digital industry exports in thefirst tier and above cities and those engaged in gener⁃al trade types.Pilot policy for innovative development of service trade can enhance the technological complexi⁃ty of digital industry exports by increasing investment in digital factors,promoting industrial spatial agglomera⁃tion and eliminating barriers to service trade.The"dual track"intellectual property protection has a positive regulatory effect in the impact of pilot policy for innovative development of service trade on the technological complexity of digital industry exports.Therefore,we should establish a nationwide innovative development net⁃work of service trade,build high-level and high standard digital industry clusters,and improve the"dual track"digital intellectual property protection mechanism,to enhance the technological complexity of digital in⁃dustry exports and form the new strengths in the competition of digtal trade.
