Study on economic factors affecting urbanization in China
利用1990-2004年全国数据建立线性模型，计算各经济因素对城市化的贡献率，发现固定资产投资（尤其是社会基础设施投资）贡献最大。
Compared with institutional factors ,economic factors play an direct and consistent role on improving urbanization. Because economic factors vary heavily, the contribution rate of each factor varies extensively as well. Based on the previous study, a linear model is established to calculate contribution rate of each economic growth factor using the national data from 1990—2004,then econometric methods are adopted to make the conclusion consistent with the practice. The conclusion is drawn that investment in fixed assets makes larger contribution to urbanization improvement than consumption and net export, especially, the investment in social infrastructure makes the largest contribution rate.
