现阶段农地非农化配置方式效率损失及农地过度性损失

Inefficiency and Excessive Loss of Farmland Conversion in China

研究目的:计算并比较现阶段全国以及长江三角洲、珠江三角洲、环渤海和成渝四大经济带农地非农化配置方式的效率损失以及农地非农化的过度性损失,以期对这些地区经济可持续发展与土地可持续利用之间关系的协调提供帮助。研究方法:通过边界生产函数模型,运用大陆31个省市的1989-1996年和1999-2002年共计12年的数据计算了农地非农化市场配置低效产生的效率损失和农地非农化过度性的损失。研究结果:虽然现阶段农地非农化市场配置效率损失在逐渐减少,但中国1989-1996年和1999-2002年阶段共计过度性农地非农化184234hm 2,占这两阶段农地非农化总数量的11.2%,其中长江三角洲和珠江三角洲地区的过度性损失较其他地区更为严重。研究结论:提高农地非农化市场配置程度是促进现阶段各地区经济可持续发展的必要条件,近期内应把重点放在长江三角洲和珠江三角洲地区的土地市场建设上。

The purpose of this paper is to compute the inefficiency and excessive loss of farmland conversion in China, and to compare the results between the four economic zones as Changsanjiao, Zhusanjiao, Huanbohai and Chengyu, in order to contribute to the sustainable development of these regions. On the theoretic analysis of inefficiency and excessive loss of farmland conversion, this paper employs panel data at provincial level to compute excessive loss of farmland conversion in China from 1989 to 2002, excluding 1997 and 1998, with the frontier production function model. The results show that the total excessive loss of farmland conversion in China is 184234 ha. in 1989 - 1996 and 1999 - 2002, which accounts for 11.2% of the total conversion amount. The excessive loss of farmland conversion in Changsanjiao and Zhusanjiao regions are more serious than that of other regions. The promotion of market allocation of farmland conversion is essential to local economic development and more attention shall be paid to the market construction in Changsanjiao and Zhusanjiao regions.
