中文摘要：

西方经典经济发展理论大多不重视土地要素对经济增长的贡献．但现阶段土地要素对我国经济增长却贡献显著。本文构建了包含土地要素的超越对数生产函数模型，运用岭回归的方法，以湖北省为例实证研究了土地要素对于经济增长的影响。研究结果表明1996-2008年土地要素对湖北省经济增长贡献显著。本文认为湖北省应从加大耕地的开发、整理和复垦力度和节约和集约利用存量建设用地两方面人手，加强对土地的科学合理利用，努力实现耕地总量的动态平衡。

英文摘要：

Most of western classic theory of economic development neglect the contribution of land element to economic growth. But 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 Hubei Province including land element, and solves the model parameters by using ridge regression. The results show that land element contributed significantly to the economic growth of Hubei Province. Two approaches for scientific land utilization are suggested： one is the economical and intensive utilization of each land and another is land development and reclamation.
