The transformation of agricultural production modes is an inevitable trend in China’s agricultural development. It is important to study the willingness of smallholder farmers to adjust their agricultural production modes to promote the transformation of China’s agricultural production modes. Agricultural production services are an effective way to realize the organic linkage between smallholder farmers and modern agriculture. To analyze the impact of agricultural production services on smallholder farmers’ willingness to adjust their agricultural production modes, this study uses data from a thematic study of 590 smallholder farmers in the Huang–Huai–Hai regions in 2022 to measure the extent of smallholder farmers’ full-cycle adoption of agricultural production services from the perspective of regional cropping systems for the first time and analyzes the impact of agricultural production services on farmers’ willingness to adjust their agricultural production modes. The study results show that the extent of full-cycle adoption of agricultural production services significantly affects farmers’ willingness to adjust their agricultural production modes. For each unit increase in the extent of full-cycle adoption of agricultural production services in line with the regional cropping system, the probability of farmers choosing “farmland transfer” and “agricultural production trusteeship” becomes 11.31 and 7.24 times higher than that of choosing “self-growing”, respectively. Based on the research results, this paper proposes the following countermeasures: first, we should pay more attention to the supply and demand of agricultural production services, especially to support the key weak links in developing agricultural production services for the process of grain production. Second, we should undertake more active and effective publicity measures to make full use of expressions that are acceptable to farmers to improve their understanding of productive agricultural services further and enhance their willingness to adopt productive agricultural services.

Currently, China is facing the problems of chaotic governance of end-use agricultural water conservancy facilities and a serious waste of agricultural water. To address the above issues, China launched a pilot policy of reforming the property rights of agricultural water facilities in 2014. In this study, we obtained data from 328 farm households through a microscopic study of the pilot property rights reform in Yunnan Province. We found that the reform has resulted in two typical property rights models: “Multiple cooperative governance” and “Private contract governance”. The impact of the reform on the maintenance quality of irrigation facilities and farmers’ water-saving technology adoption behavior was empirically analyzed using the Oprobit and IV-Oprobit methods. The study found that: (1) the property rights reform significantly improved the quality of maintenance of facilities while promoting farmers’ water-saving technology adoption behavior. (2) Heterogeneity analysis revealed that the degree of non-farming of farmers had a negative moderating effect on the quality of facility maintenance and a positive moderating effect on the adoption of water-saving technologies, and the physical health of farmers had a negative moderating effect on the quality of facility maintenance. (3) There was no significant difference in the quality of facility maintenance between the “Private contract model” and the “Multiple cooperative governance model”, but the former had higher water supply capacity; in addition, farmers under the “Multiple cooperative governance model” mainly used drip irrigation technology, whereas farmers under the “Private contract governance model” mainly used sprinkler irrigation technology. The findings of this study provide Chinese experience in promoting the governance of agricultural water facilities and promoting the water-saving behavior of farmers.

Part-time farming is a common characteristic of smallholder farmers in China at present, which is expected to persist in the long term. If China is to promote sustainable agricultural development, it is important to consider the impact of part-time employment characteristics on the grain-growing decisions of smallholder farmers. To analyze the impact mechanisms of smallholder farmers’ part-time employment on their grain-growing decisions, we used data consisting of 14,539 samples collected by a survey of the former Chinese Ministry of Agriculture National Rural Fixed Observation Point from 2009 to 2015 to empirically analyze the effect of the extent of smallholder farmers’ part-time employment on their grain-growing decisions using a dynamic panel regression model. Then, we constructed a mediating effect test model using the dynamic panel regression model as the benchmark model in order to empirically test the mediating effect of the adoption of agricultural production services. The results are as follows: as the extent of smallholder farmers’ part-time employment grows, smallholder farmers significantly reduce the sown areas of wheat and corn; furthermore, the adoption of agricultural production services is an important mediating variable to curb the negative effects of the extent of smallholder farmers’ part-time employment on their grain-sowing areas, and the “Extent of Smallholder Part-time Employment (EPE)→Adoption of Agricultural Production Services→Grain-Planting Decisions” is an important path by which the extent of smallholder farmers’ part-time employment affects their grain-growing decisions. Notably, all of the findings passed the influence mechanism test and, after a robustness test, remained valid. Based on the research findings, we propose policy recommendations, suggesting that the construction of agricultural production service systems should be improved with the orientation of high-quality agricultural development; the minimum purchase prices of wheat and corn should be appropriately increased in order to ensure that smallholder farmers receive reasonable economic returns from growing grain; and the attractiveness of growing grain to smallholder farmers should be improved.
