摘　　要：本文基于42个国家(地区)35个部门2011~2021年的面板数据,结合WWZ方法对出口贸易数据进行分解,实证探究了知识生产对出口增加值的影响。研究发现:知识生产显著促进了出口增加值,技术创新、全要素生产率在知识生产提升出口增加值的过程中起到部分中介作用。异质性检验发现,知识生产显著促进被外国吸收的国内增加值,但对出口返销国内增加值的提升效果并不显著;同时,知识生产对最终产品出口增加值、中间产品出口增加值以及中间产品转运第三方国家增加值均呈现显著拉动效果。知识生产对出口增加值的溢出效应在不同学科之间、不同种类行业之间存在异质性,材料、生化遗传学科知识生产的溢出效应相对其余学科较强。门槛效应结果显示,知识生产在不同类型出口增加值的促进作用中存在先增后减的非线性门槛特征,应防止过度的知识产权产生“创新悖论”现象,并加快技术创新与全要素生产率水平的提升。Based on the panel data of 35 sectors in 42 countries or regions from 2011~2021,this paper decomposes the export trade data with the WWZ method,and empirically explores the impact of knowledge production on export value-added.Research finds that knowledge production significantly promotes export value added,and technological innovation and total factor productivity play a partial mediating role in the process of knowledge production enhancing export value added.Heterogeneity testing finds that knowledge production significantly promotes domestic added value absorbed by foreign countries,but the improvement effect on domestic added value for export rebates is not significant;at the same time,knowledge production has a significant driving effect on the added value of final product exports,intermediate product exports,and the added value of intermediate product transportation to third-party countries.The spillover effect of knowledge production on export value added varies among different disciplines and industries,while the spillover effect of knowledge production in materials and biochemical genetics disciplines is relatively strong compared to other disciplines.The threshold effect results show that there is a non-linear threshold characteristic of first increasing and then decreasing in the promotion effect of knowledge production on the added value of different types of exports.It is necessary to prevent the phenomenon of“innovation paradox”caused by excessive intellectual property rights and accelerate the improvement of technological innovation and total factor productivity levels.
