外部性影响、准公共品分割与塔里木河流域农业开发

External influence,quasi-public goods partition and agriculture development in Tarim River Basin

塔里木河流域生态环境脆弱,随着流域农业开发活动的持续增强,产生了农业用水挤占生态用水,继而导致生态环境恶化的外部性影响,而且出现制度与管理的矫正失灵。文中从外部性和公共物品理论角度,提出由于流域的水、土资源具有准公共物品属性,而对流域准公共物品的分割管理,是导致外部性影响持续存在的重要原因。课题组还通过对塔里木河流域10个县和两个团场的750户农户进行问卷调查,进一步验证了本观点。

The ecological environment in Tarim River Basin is weak.With the basin continuing to improve agricultural development,it resulted in the conflict between ecological and agricultural water use,and led to external impact of the ecology and environment deterioration,but there is the system and the management correction failure.This article proposed the important reason of leading to continuing external impact in Basin was the result of the cut apart the management of the quasi-public goods,from the angle of external and common goods theory,for the Quasi-public goods attribute of water and land resources in basin.Research groups have further proved this viewpoint by through questionnaire investigate to 750 peasants household within 10 counties and 2 corps farms in Tarim River Basin.
