基于1978—2017年粮食主产区的投入产出面板数据和O’Donnell提出的加总数量框架，采用Hicks—Moorsteen指数将粮食全要素生产率（TFP）增长彻底分解为技术进步、技术效率、规模效率和混合效率，通过测度混合效率对主产区粮食TFP增长的贡献，进而评估要素投入结构对主产区粮食TFP增长的影响效应。结果显示：技术进步是主产区粮食TFP增长的最主要驱动因素，而要素投入结构对主产区粮食TFP增长的影响存在较大的异质性。1978—2004年内蒙古、河南、辽宁和吉林的要素投入结构变化促进了粮食TFP的增长，而其余省份则阻碍了粮食TFP的增长；2005—2017年黑龙江、吉林、河北和安徽的要素投入结构变化推动了粮食TFP的增长，而其余省份则相反。

Using the input-output panel data of the main grain-producing areas from 1978 to 2017, this paper applies the Hicks-Moorsteen index to decompose the total factor productivity (TFP) growth of the areas into technical progress, technical efficiency, scale efficiency and mixing efficiency. By measuring the contribution of mixing efficiency to the TFP growth of the areas, this paper tries to assess the effect of the factor input structure on the TFP growth. The result shows that technical progress is the most important driving factor for the TFP growth, and the effect of factor input structure on the TFP growth is relatively heterogeneous. The change to the factor input structure in such areas like Inner Mongolia, Henan, Liaoning, and Jilin in 1978—2004 has contributed to their TFP growth, while the remaining provinces have experienced a hindered TFP growth for the same period; from 2005 to 2017, the change to the factor input structure in Heilongjiang, Jilin, Hebei and Anhui has promoted their TFP growth, while it has had a contrary effect on the remaining provinces.
