Abstract
The total factor productivity (hereafter TFP) of grain production is important to achieve balanced development, while environmental factors are an important part of TEP. In order to explore the characteristics and patterns of the temporal and spatial evolution of the environmental total factor productivity (hereafter ETFP), the Malmquist-Luerberger index, and the spatial autoregressive panel (SAR panel) model were adopted to analyze the evolutionary rules and the influencing factors of ETFP. In this study, we took Poyang Lake, one of China’s main grain production areas, as a study area, and carried out empirical research based on grain production statistical data. The results show that: (1) ETFP shows a growth trend with the increase of grain production from 2001 to 2017, and a great potential for improvement exists. Moreover, from the perspective of time sequence evolution and decomposition of ETFP, which belongs to the dual-track driver of environmental technical efficiency and environmental technological progress, relevant technologies play an important role in promoting the improvement of TEFP; (2) Given that the objective conditions of gain production remain unchanged, the fact that the urbanization rate and average annual rainfall have a negative effect on ETFP, the explanatory variables such as the business scale per worker, the proportion of grain growing population, industrial agglomeration, the proportion of grain sown area and the average annual temperature all play a positive role. Among the variables, the business scale per worker and the proportion of grain growing population significantly affect ETFP at the 1% level. The average annual rainfall, industrial agglomeration and the proportion of grain sown area significantly affect the ETFP at the 5% level. The average annual temperature significantly affects the ETFP at the 10% level.

IntroductionGrain is an essential output of agriculture production
As part of consideration of environmental factors, we analyzed the ETFP of 80 counties in Poyang Lake Basin in 2001–2017
As indicated by the results, the changes in total factor productivity of grain production environment in Poyang Lake Basin were determined by environmental technical efficiency and environmental technological progress during the period from 2001 to 2017
Summary
Grain is an essential output of agriculture production. Having a sufficient grain supply is the material basis for human survival, and an important guarantee for national economic development, social harmony and stability, and national security. The Chinese central government has issued a series of policies to support and encourage agriculture development. The Chinese central government abolished agricultural taxes and has granted grain subsidies to peasants planting grains since 2014, which significantly increased the farmers’ enthusiasm and led to a steadily increase in the grain output. China has a production capacity of 600 million tons per
