An Comparable Research of Fixed Assets Investments to China's Economic Growth——Based on the Eastern、Central and Western Panel Data

本文利用面板数据,运用变系数固定效应模型对固定资产投资与经济增长之间的关系进行了实证研究。实证结果表明:固定资产投资仍是促进我国经济增长的重要原因;民营经济由于具有较高的产出弹性,是促进我国区域经济协调发展的最重要力量;在东部民营经济已经开始寻求质的提高的同时,中西部民营经济还放在量的扩张的初始阶段,东部地区外商投资也开始出现过剩迹象;而要从根本上改变中西部地区的落后面貌,加大国有投资力度不可避免。
