摘要
现阶段土地要素对我国经济增长贡献显著。本文构建了包含土地要素的超越对数生产函数模型，运用岭回归方法，实证研究了土地要素对于经济增长的影响。研究结果表明1997--2008年间，土地要素对我国经济增长的贡献率达到了20％～30％。本文认为随着我国城市化和工业化的逐步实现，年新增建设用地将不断减少，土地要素对于经济增长的贡献率也将逐渐降低。
Land element has made great contribution to China＇s economic growth at the present stage. Based on translog production function, this paper constructs an economic growth model of China including land element, and solves the model parameters by using ridge regression. The results show that the contribution rate of land element to China＇s economic growth is between 20% and 30% in 1997-- 2008. The paper also considers that, with the development of industrialization and urbanization in China, the contribution to economic growth made by land element will gradually decline.
