摘　　要：本文从土地利用结构变化的角度对土地要素的经济增长贡献进行了研究,给出一个关于中国经济增长的土地经济学解释。理论模型表明,土地要素对经济增长的影响,取决于土地利用结构变化产生的推动力、土地经济供给增加产生的推动力及传统的"增长阻力"这三种力量之综合。在非均衡增长中,这三种力量均存在。但在稳态均衡增长中,只有"增长阻力"存在。经验估算表明,改革开放以来土地要素对我国经济增长的贡献,主要源于土地利用结构变化的推动力,它是土地经济供给动力的80多倍,大规模的农用地向建设用地转移,支持了中国经济增长。土地利用结构动力的存在,完整地诠释了"尾效或阻力"理论与中国现实产生的差异。In this paper, we propose the analysis of the land contributing to economic growth, to give a land economics＇ interpretation to economic growth in China from the perspective of land use structure changes. The theoretical model shows that the impact of land for economic growth, including three forces of the ＂structure change growth drive＂, the ＂supply growth drive＂ and the ＂growth drag＂. The land＇ s net contribution to economic growth depends on these three forces. In the unbalanced growth path, these three forces are present, but in the steady - state growth path, the only ＂the growth drag＂ exists. Empirical evidence shows that China＇s land contribution to growth comes mainly from the land ＂structure growth drive＂ since 1978, and it is more than 80 times that of the ＂supply growth drive＂. Large - scale land convert from agricultural to nonagricultural, and this support the China＇s economic growth. The existence of the land ＂structural power＂ gives a more complete interpretation to the phenomenon that the land factor contributing to economic growth in China seems to be contrary to the ＂growth drag＂ theory.
