Abstract:

By using maize input-output panel data from China’s 20 provinces (municipalities and autonomous regions) in 2004 - 2018 and using DEA-Malmquist method, this paper analyzed the change of the efficiency of maize production and spatial differences in China and maize input-output redundancy in production within the study phase. At the same time, this paper used Tobit model to analyze the main factors that influencing the efficiency of maize production in China. The results show that technological progress is the main key factor to promote the growth of total factor productivity of maize in China, and the result of improvement of comprehensive technical efficiency is not obvious, which mainly depends on the increase of scale efficiency. Overall, the order of China’s maize production comprehensive technical efficiency from high to low is: the northern spring planting maize area > northwest irrigated maize area > yellow Huaihai summer planting maize area > southwest mountain maize area. In Shanxi, Liaoning, Shandong, Hubei, Yunnan, Shaanxi and Gansu Province, there is insufficient output or redundant input. The total power of agricultural machinery, the damage area and the regional difference have significant influence on the technical efficiency of maize production. Based on the research conclusions, three suggestions are put forward, first, cultivating new technical talents and strengthening the development power of maize; second, improving infrastructure to mitigate the impact of natural disasters; third, implementing structural adjustment policy and carrying out scale moderate management.
