中国省级公共投资对私人投资的动态效应研究

借助VAR模型实证分析中国省级公共投资对私人投资的动态效应,结果表明:公共投资对私人投资的影响在东部地区主要表现为挤入效应,中西部地区挤出效应更明显,东部地区从总效应中受益最大,不同地区获得的区域外公共投资溢入效应不同。原因在于不同发展阶段经济圈扩散效应和吸附效用的相对强弱不同。由于经济圈中心地区强大的吸附作用,同时邻近两个经济圈的河南、福建(长期)、贵州(长期)私人投资发展仅仅依靠本地区公共投资的带动,这在一定程度上表明省域经济发展可能存在以邻为壑的现象。

Research on Dynamic Effects of China's Provincial-Level Public Investment on Private Investment

Eastern parts benefit most from total effects. Different regions get different spillovers,due to the relative strength of absorption and proliferation effect at different development stages. Because of stronger absorption of central regions,the development o...
