Establishing an inter-provincial horizontal interest compensation mechanism for grain production and sales areas is of great significance as an institutional arrangement to balance the economic interests between the main grain production areas and the main sales areas,in order to improve the enthusiasm of grain production areas and ensure national food security.Based on economic and ecological perspectives,fully considering the explicit and implicit losses in the development of major production areas,the horizontal compensation standards and compensation amounts for grain production and sales intervals are comprehensively calculated from aspects such as grain transportation losses,implicit costs of arable land,implicit costs of labor,agricultural carbon balance,and agricultural water resources.The results showed that:(1)from 2013 to 2022,the compensation amount for grain production and sales areas has been continuously increasing,with a 9.5%increase over the past 10 years.Among them,the hidden costs of arable land and labor constitute the most important part of the compensation amount,accounting for more than 95%of the total compensation amount.(2)The cultivation of grain in the main production areas had brought great ecological benefits,and the net carbon value of agriculture in the main production areas had increased from 103 524 200 tons in 2013 to 145 746 400 tons in 2022.(3)Heilongjiang Province and Inner Mongolia,as major grain producing provinces,had the highest economic and ecological compensation amounts among the main production areas,accounting for 33.28%of the total national compensation amount.Guangdong Province,Beijing City,and Zhejiang Province were the main compensation provinces,with compensation amounts ranking among the top sales areas,accounting for 71.38%of the total national compensation amount.Therefore,it is important to pay attention to implicit cost compensation in grain production and sales areas,while considering ecological compensation,in order to promote the sustainable development of ecological compensation and grain production areas.
