摘  要:2001-2016年中国苹果产量持续增长,通过对全国及苹果主产省苹果产量、单产和面积变化情况的分析以及苹果产量增长贡献率的分解发现,苹果产量的增加主要靠单产的提高。在此基础上,文中运用2001-2016年七个苹果主产省的数据,构建了C-D单产函数模型,分析各种投入、技术进步和气候对苹果单产的影响。结果表明,苹果单产提高的传统动能是农药、化肥、人工的投入和良好的气候条件。然而,苹果生产已处于投入要素规模报酬递减阶段,传统动能面临着一系列障碍。为克服这些障碍,文中提出了苹果产业新旧动能转换的对策措施。China’s apple production continued to grow from 2001 to 2016. By analyzing the changes in apple yield,yield per unit and area,and decomposing of the contribution rate of apple’s production growth,we found that the increase in apple production depended mainly on the improvement of yield per unit. On this basis,we constructed a single production function model to analyze the effects of various inputs,technological advances and climate on apple’s yield per unit,by using the panel data of the seven apple production provinces from 2001 to 2016. The results indicate that the traditional kinetic energy of apple’s yield per unit increase is the investment of fertilizers,pesticides and favorable climatic conditions. However,apple production has already been in the stage of diminishing returns of input factors,and traditional kinetic energy have faced a series of obstacles. In view of these obstacles,we put forward the countermeasures to build new kinetic energy of apple industry.
