摘　　要：本文基于内生经济增长理论构建了反映公共资本与技术进步之间关系的实证框架;在此基础上,利用我国29个省1988-2007年相关面板数据对公共资本、省际溢出与全要素生产率间的长期关系进行了协整检验。实证结果表明,在长期中,"硬"公共投资比"软"公共投资具有更大的技术进步效应;无论是"硬"公共投资,还是"软"公共投资,各项构成的技术进步效应均表现出一定的差异;"硬"公共资本和"软"公共资本对技术进步的跨区溢出呈现不同态势。In this paper,we construct an empirical framework for exploring the relationship between public capital and technological progress based on endogenous growth theory.On this basis,we make cointegration test to long-term relationship among public capital,inter-provincial spillovers total factor productivity using panel data of 29 provinces from 1988 to 2007 in China.The empirical results show that the ＂hard＂ public investment has a greater effect of technological progress than the ＂soft＂ public investment in the long run;Whether it is ＂hard＂ public investment,or ＂soft＂ public investment,that technological progress effects of its composition have shown significant differences;The cross-regional spillovers to technological progress of ＂hard＂ public capital and ＂soft＂ public capital show different situation.
