摘要
经济的快速发展引致了对建设用地的大量需求，人地矛盾日益尖锐。倡导城市建设用地的集约利用是实现经济社会可持续发展的有效途径，而提高土地利用集约水平需要掌握其影响因素的作用机理，辨识主导因素。本研究基于影响土地集约利用的经济、制度和生态因素等构建了土地集约利用影响机理的一般理论分析框架，并利用我国1989年～2004年的社会经济和土地利用数据构建计量经济模型对其进行实证研究。研究的结果表明：经济发展和土地市场化发育程度是影响对土地利用集约化水平的重要因素；政府对农地的保护制度在一定程度上激励用地者集约利用土地；而对生态环境的保护是控制土地利用集约度限制性因素；从整体上看，市场化发育水平是影响我国土地利用集约程度的关键性和根本性原因。
Rapid economic development may induce much demand on constructive land, and lead to great conflicts between human and land. According to some research conclusion, farmland decreased by 4 701 500 ha because of the rapid economic development in China from 1978 to 2003. That is to say, about 293 400 ha of farmland are converted to construction land annually. So, it is important to know the factors that influence land use and the mechanism of intensive land use. On the basis of analysis of the economic, social system and environment factors that influence land use intensity, this paper established a theoretical framework to analyze the mechanism of land use intensity and the factors that influence land use intensity in China by using the data of economy, society and land use from 1989 to 2004. The results indicated that at 0.01 significant levels, GDP and the land market degree are positively related to the land use intensity. At 0.05 significant levels, the protection of farmland is important to improve the intensity of land use. At 0.1 significant levels, the policy to induce the mature of land market is good to improve the intensity of land use. So, economic development and land market degree are the most important factors affecting the intensity of land use. The government policy in farmland protection, to some degree, encouraged the practice of intensive land use. However, the measures to protect environment may control the extent of land use intensity. Generally, the degree of land market is the key factor to influence the intensity of land use in China.
