“…In light of this finding, we set the postharvest loss rate for producers as λ = 0.1. According to Li et al (2020), the use of loss reduction technologies can reduce the grain loss rate for producers by approximately 2.5%. Based on this estimation, the theoretical attenuation coefficient for the number of producers after adopting loss reduction technologies should be within (0, 0.77).…”

To reduce agricultural pollutant emission (APE) and postharvest loss of grain (PHLG), the Chinese government enacted a series of subsidy policies; however, the profit-oriented supply chain members are seriously lacking or reducing APE and PHLG efforts. To address this issue, we considered as the research objective a grain supply chain consisting of a producer, a retailer and the government. We proposed the concept and functional expressions of supply chain members' reduction efforts for APE and PHLG. We then proposed two main variables: the environmental innovation subsidy coefficient and the quantity attenuation factor of grain. According to the actual situation, four investment subsidy models were proposed. The results showed the following: i) supply chain members' equilibrium prices and incomes were negatively correlated with the degree of the producer's APE effort regardless of whether the supply chain members were investing in PHLG technology; ii) when the government subsidises APE and PHLG technology for other supply chain members, the government should stop subsidising the retailer's inputs in reduction loss technology to ensure that the government's own interests are not damaged; iii) the government's income was restricted by the degree of its subsidising of other supply chain members. This study provides a theoretical support for the government to formulate appropriate policies to reduce APE and PHLG, which is important for maintaining national food security.

“…In contrast to the meticulous procedure of traditional harvesting, machine harvesting is clumsy and prone to damaging or missing grain [38,41]. Grain varieties differ in how harvesting practices affect harvest loss [42]. Segmented harvesting explicitly minimizes the loss of maize harvest but has no discernible impact on the loss of wheat and rice.…”

Previous studies have demonstrated that grain loss in the harvest process accounts for a large loss in all aspects of the grain supply chain. This research extensively discusses the impact of farmland management scale on grain loss in the harvest process based on survey data on farmers’ productivity in the Shandong and Hebei provinces of China. The findings revealed that the scale of farmland operation directly influenced the grain loss during harvest and that this effect is greatly reduced as the farmland operation scale increases. This study also constructed an intermediary model, investigated the influence mechanisms, and added agricultural capital as a variable in the harvest link. It was discovered that the scale of agricultural land management has an indirect effect on grain loss in the harvest link via the input of agricultural capital in the harvest link. The increase in agricultural capital investment in the harvest link considerably reduced this effect. In order to decrease grain losses during the harvest process, this paper suggests expanding the size of agricultural enterprises, developing new agricultural corporate organizations, and further playing the role of the rural land market.
