基于CVM法的农户保持退耕还林的接受意愿研究-以重庆万州为例

Famers' willingness to accept for maintaining the grain for green:An empirical analysis based on Wanzhou district in Chongqing

退耕还林今后的主要任务是如何保持和巩固既有成果,退耕户的态度至关重要。文中以重庆万州197份有效调查样本为依据,采用条件价值评估方法 (CVM)实证分析农户保持退耕还林的接受意愿(WTA)。结果发现:补贴依然是农户保持退耕还林的主要激励,单边界和双边界二分式CVM的农户平均WTA分别为61.89元/亩·年和107.76元/亩·年;显著影响农户WTA的因素是农户对退耕还林政策的经济功能认知、家庭劳动力数、家庭收入、种植业的重要性。巩固退耕还林成果应该建立在促进农村劳动力非农就业、不断提高农村经济发展水平和增加农户收入的基础之上。

The major task of China~ Grain for Green Project for the future is how to maintain and consolidate ex- isting achievements. Based on the survey data from Wanzhou district in Chongqing, the contingent valuation method （CVM） was applied to empirically analyze the farmers＇willingness to accept （WTA） for maintaining the Grain for Green. Results show that the subsidy remains to be the major incentive for farmers＂ maintaining the pro- jectg achievements and their average WTA resulted from the single -bounded and double -bounded dichotomous CVM analysis are 61.89 Yuan/mu ~ a and 107.76 Yuan/mu ~ a respectively. The factors significantly influen- cing the farmers＂ WTA include their policy perception of the project＇s economic function, household income, number of family labors and the importance of farming. It suggests that maintaining the project＇s achievements should be based on a foundation of promoting rural labors＇non - farming employment, improving the level of rural economic development and increasing farmers＂ income.
