摘要: 多样化种植是满足食物有效供给与应对气候变化的重要策略。利用来自中国粮食主产区的1 201份农户生产经营数据,基于内生转换回归模型和分位数回归模型,实证探讨了农户实施多样化种植对种植业净收入的影响。研究结果显示:(1)与未实施农户相比,实施多样化种植农户的种植业净收入实现了显著增长。(2)在种植业净收入不同水平的农户之间,其实施多样化种植的收入效应存在差异。其中,种植业净收入水平较低的农户实施多样化种植后种植业净收入显著增长,而种植业净收入水平较高的农户未能显著受益。(3)不同程度的多样化种植对农户种植业净收入的提升效果存在差异。随着多样化种植程度的提高,其对农户种植业净收入的提升作用先增强后减弱,当多样化种植指数SID处于(0.4,0.5\]区间时,提升作用较强。基于此,相关政府应针对种植业净收入不同水平的农户实施差异化推广策略,重点鼓励种植业净收入水平较低的农户实施多样化种植。同时,应引导农户发展适度多样化种植,以促进其种植业净收入增长。

Abstract: Diversified planting emerges as a pivotal strategy in ensuring effective food provision and addressing the challenges of climate change. Based on data from 1 201 farmers in China’s major grain-producing regions of China, this study empirically explored the impacts of diversified planting implementation on farmer′s   net plantation income, by employing the endogenous switching regression and quantile regression models. The results showed that: (1) Farmers that adopted diversified planting experienced a significant increase in net plantation income, compared to the non-adopters. (2) Variations existed in the income effects of diversified planting implementation among the farmers with different degrees of net plantation income. Specifically, the farmers with a lower net plantation income witnessed a substantial increase in net plantation income following the diversified planting, while the ones with higher net plantation income counterparts did not have significantly benefits. (3) The extent to which diversified planting might enhance farmer′s   net plantation income varied depending on the degree of diversification. The efficacy of diversified planting in enhancing farmer′s  net plantation income initially strengthened and subsequently diminished as the degree of diversification increased. When the diversification index (SID) was in the range of (0.4,0.5\], the enhancing effect was notably strong. Based on the above conclusions, it was imperative for relevant governments to develop tailored promotional strategies that matched the farmers with varying levels of net plantation income. There should be a particular emphasis on guiding and encouraging farmers with lower levels of net plantation income to engage in diversified planting. Furthermore, it was essential for the government to assist farmers in selecting the appropriate degree of diversification to enhance their net plantation income.
