Abstract
The corn production cost (CPC) in China is related to national food security. However, there are few studies on the temporal and regional differences (TRD) and sensitive factors in the CPC. In this paper, the TRD of the corn production cost across various regions, as well as over the entirety of the country from 2008 to 2018, is presented. It is based on the GIS exploratory spatial data analysis method (ESDA). Simultaneously, a spatial panel model is established to conduct an empirical analysis of the main factors affecting the CPC. The results from the period in question show that the CPC in China and the three major production regions present a fluctuating growth trend, mainly associated with the increase in labor prices. Moreover, the CPC exhibits significant spatial differences, and demonstrates an overall trend of gradual increase from the east to the west. Over time, the number of relatively high-cost provinces has increased. All are located in southern mountainous and hilly corn areas. In addition, the CPCs of various regions are spatially correlated. Factors such as the scale of land management, the degree of mechanization, and socioeconomic conditions have a significantly negative impact on the CPC in China. Furthermore, the labor structure has a notably positive impact on the CPC.
Highlights
Academic Editor: Zhao ZhangThe development of grain production is interconnected with the economic benefit of Chinese farmers, but with the country’s grain security as well
The production cost of food and other agricultural products is primarily defined from the perspective of the economic and accounting cost in Western economics
The results firstly indicate that the production costs in China and the three major corn producing regions have a fluctuating upward trend from 2008 to 2018, which is mainly related to the surge in labor prices
Summary
Academic Editor: Zhao ZhangThe development of grain production is interconnected with the economic benefit of Chinese farmers, but with the country’s grain security as well. The aforementioned situations constitute the strange phenomenon of the Chinese grain “three-quantity increase” [2]. The occurrence of this phenomenon may be attributed to the ceiling effect of Chinese agricultural product prices and the squeeze effect of rising cost floors [3]. China is both the second largest corn producer and consumer in the world, just after the United States. Corn production has continuously been exceeding rice output since 2012 and, ranking first in Chinese grain output. It may be concluded that corn occupies an important position in Chinese food security
