Farmers' land allocation responses to the soybean rejuvenation plan: evidence from “typical farm” in Jilin, China

Abstract

PurposeThe purpose of this paper is to test the impact of the soybean rejuvenation plan and the subsidy on farmers' land allocation decisions, which may reference policy adjustment from a micro perspective.Design/methodology/approachThe paper develops a multi-objective optimized programming model on farm-level, which simulated the land-use changes, as well as the resulting changes in benefits of the rational “typical farm”. The simulation scenarios include changes in subsidy policy and production efficiency, and the baseline scenario was the production status in 2018.FindingsThe results show that an increase in soybean producer subsidy will encourage farmers to allocate more land for soybean planting, which can be considered as a policy tool in promoting soybean production in China. Besides, the effect of subsidy in adjusting soybean acreage for farms is further affected by external conditions such as production technology (such as breeding technology, pesticide and fertilizer application efficiency). Meanwhile, large-scale farms show more significant land adjustments when facing changes in policies and external conditions.Originality/valueThe value of this paper is to simulate the effects of soybean policy and subsidy change on farmers' land-allocation decisions through a multi-objective farmer decision-making model, which provides a micro perspective to understand the implementation effect of the soybean revitalization plan.

“…The Chinese government initiated the second round of the soybean revitalization plan in 2018, aiming to promote area expansion and production for the sustainable development of the soybean industry [48]. The Ministry of Agriculture officially released the implementation plan for the soybean revitalization, which clearly stipulated the requirement to increase soybean area in key regions, striving for a total national cultivation area of 140 million mu (9.3 million hm 2 ) by 2020 [49]. Under the guidance of these policies, the soybean area in the WLRB experienced a significant increase trend from 2018 to 2020.…”
