中国土地投资函数的参数估计

Parameter Estimation for Land Investment Function of China

研究目的:推导中国的土地投资函数,解析土地价格对投资的影响因子,并以北京、上海、宁波、广州、天津、沈阳6城市为样本进行地区影响分析。研究方法:计量经济法,模型分析法。研究结果:土地价格每上升1个百分点,工业投资就会下降0.00765个百分点。上海、宁波、广州、天津4个城市的医药、电子和食品制造业投资对土地价格变化最为敏感。研究结论:土地价格对工业投资有一定影响,工业投资对土地价格的弹性有明显的行业和地区特点。

The factors of land purposes of this paper are to deduce the land investment function of China, analyze the influential prices to the investment, and to analyze the regional influences by taking 6 cities, i.e., Beijing, Shanghai, Ningbo, Guangzhou, Tianjin and Shenyang, as samples. Methods employed include econometrics arid model analysis. The results indicate：（ 1 ）the industrial investment amount will drop 0.00765% if the land prices increase 1%; （2）the investment amounts in medical, electronic and food manufacturing industries in Shanghai, Ningbo, Guangzhou and Tianjin are the most sensitive to the variation of land prices. It is concluded that the land prices have certain influences on industrial investments and there exist remarkable industrial and regional features in the elasticity of industrial investments to land prices.
