摘要
实施保护性耕作是保障国家粮食安全和实践“藏粮于地、藏粮于技”战略的重要举措。基于保护性耕作适宜区427户种粮农户的微观调查数据,采用条件价值评估法和构建的等效用函数测算保护性耕作的补偿标准,运用二元Logistic模型分析农户受偿意愿的影响因素。结果表明:(1)采用条件价值评估法测算的保护性耕作补偿标准为735.98元·hm^(-2),经等效用函数修正后的补偿标准为410.07元·hm^(-2),两者差异较大;(2)采用条件价值评估法测算的农户受偿意愿往往较高,在考虑农户个体及社会经济特征的影响后,经过等效用函数测算的农户受偿意愿结果更贴合实际情况,因此,可将其作为样本地区实施保护性耕作的最低补偿标准;(3)两种方法测算得到的粮食主产区农户受偿意愿均高于样本总体农户受偿意愿,因此,开展保护性耕作补偿工作的重心应聚焦在粮食主产区;(4)样本总体农户受偿意愿受到农户个体特征和认知特征的影响,粮食主产区农户受偿意愿除受到上述因素的影响外,还受到农业劳动力人数和家庭总收入的显著影响。研究结论对于地方政府科学制定保护性耕作补偿标准、推动农户实施保护性耕作具有重要的参考价值和借鉴意义。
Conservation tillage is the important initiative to guarantee national food security and realize the strategy of"Storing Grain in Land and Technology".Based on the micro-survey of 427 grain-growing farmers in the suitable area of conservation tillage,the compensation standard of conservation tillage was measured by using the contingent valuation method and the constructed equivalent utility function,then the factors affecting farmers′willingness to accept was analyzed with the binary Logistic model.The results show:(1)The compensation standard for conservation tillage calculated by the contingent valuation method is 735.98 yuan·hm^(-2),and the one after being corrected by the equivalent utility function is 410.07 yuan·hm^(-2),with a significant difference between them.(2)The farmers′willingness to accept measured by the contingent valuation method tends to be higher,and after considering the influence of the individual farmers and socio-economic characteristics,the farmers′willingness to accept measured by the equivalent utility function is more appropriate to the reality,thus,it could be considered as the minimum compensation standard for implementing conservation tillage in the sample areas.(3)The farmers′willingness to accept in the main grain-producing areas measured by both methods is higher than the overall willingness of farmers in the sample areas.Therefore,the emphasis of carrying out conservation tillage compensation should be concentrated on the main grain-producing areas.(4)The overall sample of farmers′willingness to accept is affected by the individual characteristics and cognitive characteristics of farmers.In addition to the above factors,the farmers′willingness to accept is significantly affected by the number of agricultural laborers and aggregate household income in the main grain-producing areas.The findings of the study have theoretical and practical contribution for local governments to scientifically formulate conservation tillage compensation standards and promote farmers to
