本文对固定资产投资乘数、凯恩斯投资乘数和投入产出投资乘数等三种投资乘数进行了测算分析,结果表明近年来我国投资乘数并没有发生大幅度下降,对经济增长的拉动贡献较大。通过对4万亿投资计划的具体测算,表明投资对拉动内需和抵御外部冲击发挥了巨大作用。作为发展中国家,保持较高的投资增速是经济可持续发展的必要条件,未来投资仍将是拉动我国经济增长的主要动力。但应当积极调整投资结构,避免产能过剩、抑制房地产价格上涨,提高投资效率。
In this paper, we estimated the fixed asset investment multiplier, Keynesian investment multiplier and input-output multiplier. The results show that investment multiplier has not declined significantly in China in recent years, and the contribution of investment to GDP is still large. Through the specific calculation of the multiplier effects of 4 trillion investment plans, we find that investment still plays an important role in economic growth as well as withstanding external shocks. As a developing country, to maintain a high growth rate of investment is necessary for economic sustainable development, so investment will remain one of the major driving forces of growth in future. But China must proactively adjust the investment structure to avoid excess capacity, curb real estate prices, and improve investment efficiency.
