【摘要】：线性结构的Coe-Helpman模型只能测度货物贸易的物化型知识溢出效应。本文基于非物化型知识的空间属性将线性结构的Coe-Helpman模型在空间维度扩展为具有非线性结构的Coe-Helpman-Durbin模型,用于对比研究货物贸易与服务贸易的非物化型知识空间溢出效应。基于中国31省1992-2011年面板数据的检验结果表明:货物贸易与服务贸易非物化型知识的首次溢出均未能提升贸易进口地的全要素生产率、技术进步率和技术效率;但服务贸易非物化型知识的二次溢出却提升了进口地以外其他地区的全要素生产率、技术进步率和技术效率;而货物贸易非物化型知识的二次溢出仅提升了进口地以外其他地区的技术效率。
[Abstract]:The Coe-Helpman model of linear structure can only measure the materialized knowledge spillover effect of goods trade. In this paper, based on the spatial attributes of immaterialized knowledge, the Coe-Helpman model of linear structure is extended to a Coe-Helpman-Durbin model with nonlinear structure in the spatial dimension, which is used to compare the spatial spillover effects of non-materialized knowledge between trade in goods and trade in services. Based on the panel data of 31 provinces in China from 1992 to 2011, the results show that the first spillover of non-materialized knowledge of trade in goods and services has failed to improve the total factor productivity, technological progress rate and technical efficiency of the place of import, but the secondary spillover of the knowledge of non-materialized knowledge of trade in services has improved the total factor productivity, technological progress rate and technical efficiency in other areas other than the place of import. However, the secondary spillover of non-materialized knowledge of goods trade only improves the technical efficiency of other areas other than the place of import.
