直接影响和空间溢出效应：知识资本对中国工业全要素生产率的影响研究

在供给侧改革背景下，对全要素生产率的来源分解和影响研究具有现实意义。本文基于1998～ 2014年间我国31个省的面板数据，选取合适的空间计量模型实证了知识资本投入对我国工业 全要素生产率的直接影响以及空间溢出效应。研究结果显示：知识资本投入与全要素生产率之间有正相关的联系，其中东部地区知识资本对全要素生产率的直接影响和空间溢出效应都最为明显，中部次之，西部无明显的空间溢出效应；不同时期内知识资本与全要素生产率之间的关系也存在很大差异，1998～2006年间空间溢出效应微弱，2007～2014年间直接影响和溢出效应都有加强。

Direct and Spillover Effects: The Empirical Analysis of Knowledge Capital Impact on Total Factor Productivity of Chinese Industry

This paper is of practical significance on the source of the total factor productivi ty under the background of supply side reform.This paper is aiming at the direct impact of knowledge capital investment on China's industrial total factor productivity and the spatial spillover effect by using appropriate spatial econometric model,according to the provincial data from China in the period of 1998-2014. The results show that there is a positive correlation between knowledge capital investment and total factor productivity,the direct impact of knowledge capital on total,factor productivity and spatial spillover effect is the most obvious in the eastern region of China,and the middle of the second,there is no obvious spatial spillover effect in the West.It also shows that the relationship between knowledge capital and total factor productivity is very different in different period.It also shows that the spatial spillover effect of 1998-2006 is weak,and the direct impact and spillover effects of 2007-2014 are strengthened.
