摘要
基于实证分析的结果显示,在我国不同发展时期和不同地区经济发展过程中,投资增长对GDP增长的边际贡献随市场化程度和经济发展水平的提高而逐渐减弱;调控国家预算内投资和国内信贷对经济增长的直接影响是不显著的,但它具有明显的引导作用。就不同区域经济发展而言,各地区投资增长对GDP增长的边际贡献依经济发展水平和东中西部地理位置差异近似呈“倒U型”关系。
The result of an empirical analysis shows that the marginal contribution of investment growth on GDP growth weakens gradually as the degree of marketization and the level of economic development increase. The effect of change in the budgeted investment and domestic credit on economic growth is insignificant, but it serves as a leading indicator. As far as different regional economic developments are concerned, the marginal contribution of investment growth on GDP growth in different areas presents an inverse U shape relationship depending on the economic development level and geographic position differences of the east, the middle and the west.
