摘要: 2004年以来我国主粮生产成本快速上升,一些主粮主产省份的成本优势趋于减弱,甚至转为劣势,对种粮效益、粮农增收和粮食安全带来了负面影响。基于要素成本贡献度分解法,从全国与主产省份两个层面,分作物实证分析了我国主粮生产成本快速上升之源。结果发现:就全国主粮生产平均成本来看,劳动力成本是对生产总成本上升贡献度最高的要素成本,而劳动力价格特别是家庭用工机会成本的提高,是推动劳动力成本以及粮食生产总成本持续上升的主因。但是,由于各种主粮作物要素投入结构不同、各地粮食生产方式和条件也有区别,要素成本贡献度结构存在作物间和省际间差异。就不同作物和不同主产省份来看,主粮生产成本上升的主次成因不尽相同。

Abstract: Since the year of 2004, the production cost of China's staple crops has increased rapidly and the cost advantages of some staple grain producing provinces tend to be weakened or even turned into disadvantages, which brings a negative impact on grain production benefit, farmers' income growth and food security. Based on the method of decomposition of factor cost contribution, this paper empirically analyzes the source of the rapid increase of the production costs of classified China's staple crops at both national and provincial level. The results show that, in terms of the average cost of the staple crops at the national level, the labor cost is the factor cost with the highest contribution to the increase of total production costs, while the labor price, especially in the opportunity cost of family self-employment is the main driving force for the continuous increase of labor cost and the total costs of grain production. However, due to different input structures of various staple grains factor as well as different grain production modes and conditions in different regions, there exist inter-crops and inter-provincial differences in the structure of factor cost contribution. In terms of different crops and different major producing provinces, the primary and secondary causes of the rising costs of staple crops production are not the same.

Key words: staple crops production cost, decomposition of factor cost contribution, labor cost
