摘要
建立Tornqvist指数模型,计算了全国和河南、山东小麦生产的全要素生产率.结果表明,全国小麦总产增加主要来源于单产提高,而单产提高主要决定于全要素生产率增长,要素投入是小麦单产提高的物质基础.2001年以来,全要素生产率增长明显放缓,但河南省全要素生产率仍有较大优势.在压缩或稳定播种植面积的情况下,未来小麦总产增长关键是提高全要素生产率.
This paper estimated the wheat total factor productivity (TFP) for national and two major producing regions Henan Province & Shandong Province, based on the Tornqvist index model. The re- sults showed that China' s aggregate wheat production was determined by wheat yield while the yield increase was mainly determined by the TFP improvement, but factor inputs were the foundation of wheat yield increase. Since 2001, the TFP increase apparently slowed down, but Henan' s TFP still had larger advantage. Given that sown area was shrunk or stabilized, it is crucial for Henan to improve TFP in order to increase total wheat output in the future.
