中国粮食生产的范围经济实证研究

The Study on Scope Economies of Grain Production in China

基于2011年农村固定观察点数据,通过广义超越对数成本函数,对中国粮食、经济作物、畜牧养殖产业的范围经济,以及农业生产的总体范围经济进行测度。研究结果显示:中国农业总体生产存在范围经济现象,但不同省份之间范围经济程度差异较大;粮食作物生产与畜牧养殖均呈现范围经济,且两者之间存在较强的成本互补性,但经济作物的范围经济程度相对较弱;农户混合经营的方式也催生出"多元化经济"与"专业化经济"的矛盾。虽然农户混合经营的情况短时间内仍会继续维持,但还需专业化的分工以确保其规模经济。

Based on the data of rural fixed observation points in 2010,the industrial scope economy of China＇s grain,economic crop and animal husbandry,and the overall scope economy of agricultural production are measured by the generalized translog cost function. The results showthat there is obvious scope economy in the agricultural production in China,but different provinces are different greatly. Grain production and animal husbandry have obvious scope economy,and there is a strong complementarity cost between them,but the scope of economic crops is relatively weak. In addition,the way of farmers mixed operation also spawns a ＂diversified economy ＂and ＂specialized economy ＂. Although the situation of farmers＇ mixed operation will continue to be maintained in a short period,it is still necessary to make professional division of labor to ensure its economies of scale. In viewof this,this paper puts forward policy suggestions from two aspects of improving agricultural specialization service and agricultural insurance.
