摘　　要：提高出口技术复杂度(EXPY)有助于培育贸易新动能,通过技术驱动实现高质量发展。文章从生产性服务出口贸易视角出发,利用104个国家(地区)2005—2018年的跨国数据,实证检验了生产性服务EXPY与经济增长之间的关系,验证了其驱动增长的技术创新机制,并进一步分析了不同知识密度下生产性服务EXPY的异质性经济效应。研究发现:提升生产性服务EXPY能有效提高经济增速,促进经济增长;生产性服务EXPY的提速效应主要通过技术创新机制实现,有可能实现质量型增长;高知识密度生产性服务行业EXPY提升对经济增速存在正向影响,而低知识密度生产性服务行业EXPY的提升则会产生负向影响。在当前构建双循环新发展格局的背景下,坚持服务业对外开放,提升生产性服务EXPY,实现传统贸易结构转型升级,向专业化和价值链高端延伸,是实现高质量发展的有效支撑。Improving export technological complexity( EXPY) is helpful to cultivate new momentum of trade,so as to achieve high-quality development driven by technology. From the perspective of productive services export,the paper uses the transnational data of 104 countries from2005 to 2018 to empirically test the relationship between EXPY of productive services and economic growth,which verifies the technological innovation mechanism that drives economic growth.Furthermore,the heterogeneous economic effects of productive services ’ EXPY under different knowledge density are analyzed. The results are shown as follows: Improving the EXPY of productive services can effectively increase economic growth rate and promote economic development.The speed-up effect of productive services’ EXPY is mainly achieved through the mechanism of technological innovation,which may promote quality economic growth. The increase of EXPY in high knowledge-intensive productive services industry has a positive impact on economic growth,while the increase of EXPY in low knowledge-intensive productive services industry has a negative impact. Under the current background of building a new development pattern through dual circulation,adhering to the opening-up of the service industry,improving the EXPY of productive services,realizing the transformation and upgrading of the traditional trade structure,and extending to the specialization and the high-end of value chain are the effective supports to achieve high-quality development.
