The Grain-to-Fodder Crop Conversion Program (GCCP) in China mainly promotes the green and sustainable development of grain crops, economic crops, and silage crops by subsidizing livestock farms to encourage farmers to plant silage crops, such as corn silage and alfalfa silage. In this context, this study assesses the impact of planting silage crops on farm household income. Based on a survey of 495 households in Henan and Hebei Provinces, China, we first constructed a theoretical model of the program’s effect on farmers’ income, and then used an ordinary least squares (OLS) method to estimate the magnitude of the GCCP on farmers’ income. To identify endogeneity and further test the stability of the results, we adopted instrumental variable estimation, subsample estimation, and matching methods. The GCCP significantly increased smallholder farm income. Compared with growing corn grain, corn silage increased income by approximately CNY 101/mu. Meanwhile, corn silage reduced the capital input cost of farmers by 10.71% per mu and labor input by 26.6% per mu. Heterogeneity analysis revealed that farmers who plant corn silage on a large scale, closer to dairy farms, have higher incomes. Few scholars have empirically analyzed the impact of GCCP on farm household income from a micro-farm household perspective. This study enriches the empirical literature on the effects of the GCCP on farmers in China, which can help policymakers understand policy implementation.

This study examines the effects of the Regional Comprehensive Economic Partnership (RCEP) on the value-added trade of food and non-food sectors. This study uses a global computable general equilibrium (CGE) model coupled with an extension module for the origin decomposition of value-added flows embodied in gross trade. The results suggest that by cutting down tariff and non-tariff barriers, the RCEP would significantly stimulate the economies of and gross trade among Asia–Pacific countries involved in the agreement. The potential benefits of the RCEP will be overestimated if we ignore the origin of value added and measure the benefits by gross exports. The domestic components of bilateral value-added flows between RCEP members would increase greatly, indicating an increasingly integrated value chain between RCEP members. Import taxes and non-tariff barriers for processed food, textiles and clothes, and heavy manufacturing are relatively significant in the region, so the RCEP would significantly improve their value-added exports. The domestic component of value-added exports in agricultural products and processed food from RCEP members would be increased significantly, indicating that the closely integrated food value chain boosts the food economies of RCEP members.
