我国城乡固定资产投资规模与优化配置

Study on the Scale and Optimization for Urban-rural Investment in Fixed Assets of China

通过对1980～2005年间我国城乡固定资产投资情况进行比较分析，从中寻求其特征和规律，作为指导投资的依据。进而从预测未来经济增长速度、确定固定资产投资率入手，对我国2006～2020年度全社会固定资产投资总量进行测算。在此基础上，以公平和效率为原则、以缩小城乡居民人均收入差距为目标，建立模型，对投资总量进行城乡间的优化配置。最终得出结论：在各自投资规模持续增长的基础上，城乡之间的投资差距将不断缩小，从而确保资金的最优配置和城乡统筹发展。

From the reform and opening up, the gap of urban-rural investment in fixed assets （IFA） has continually increased, which deeply influence the realization of urban rural balanced development. There fore, it is significant to confirm reasonable urban-rural IFA scale. This paper analyzed the urban-rural IFA of China from 1980-2005, sought for the principle and characteristics to guide investment. Then via fore casting the GDP growth rate and determining the rate of IFA, it got the annual amount of IFA in China from 2006-2020. Aiming at reducing the urban-rural income disparity, it sets up a series of model to optimize the investment between urban and rural. Finally, it drew the conclusion that on the basis of continually increase of respective scale, the gap should be unceasingly reduced, so as to insure optimization for urban rural IFA and balanced development.
