In the context of the Household Responsibility Systems, farmland is regarded as the most important household assets for apple growers, and equal distribution of land resulting from the systems of farmland property rights resulted in the issue of land fragmentation and had difficulty in reducing the costs of agricultural production, which restricted the improvement of agricultural income. But with human society entering into the informatization era, informatization re-plasted the specific situation of the development of farmland transfer markets and improved the ability of information acquisition and information processing, which changed profoundly the allocation efficiency of rural factors and consequently, provided an important opportunity for improving agricultural income. Thus, this paper established a theoretical framework for impacts of informatization on farmland transfer and agricultural income from the perspectives of reducing the transaction costs of participating in farmland transfer and strengthening the cognition of land tenure security, which was empirically examined by using OLS model, Logit model, Ologit model and the survey data of 762 apple growers. The results indicate that:the application of informatization tools such as mobile phones not only boosted significantly agricultural income at the 5% level, but also increased significantly the size of transfer-in farmland at the 1% level. Further, the size of transfer-in farmland was a partial mediating variable for positive impact of informatization on agricultural income. After using these methods such as replacing the proxy variables, excluding the competitive mechanisms and instrumental variables method, above-mentioned results were still robust. From the perspective of the influencing mechanisms, informatization enhanced significantly the size of transfer-in farmland and improved the land accessibility by reducing searching costs and negotiation costs of participating in farmland transfer markets, and searching costs and negotiation costs were the partial mediating variables for positive impact of informatization on the size of transfer-in farmland. However, the application of information tools such as mobile phones did not significantly improve farmers' recognition of the farmland ownership, the recognition of land rights including transfer right and mortgage right, and the recognition of the extension of the term of land contract right for another 30 years because farmers did not use information-based tools such as mobile phones to understand the relevant information about land rights. Based on the above research results, this paper puts forward the following policy recommendations:1) The application of information tools such as mobile phones and computers in rural areas should be supported and encouraged to strengthen the awareness and ability of information acquision for agricultural operators to participate in the factor markets. 2) The reform of farmland property right systems with the aim of reducing the expectation of the risk of farmland property right should be deepened, and a variety of information tools should be actively used to publicize the content of farmland property rights system reform, which changes the traditional concept or cognition for farmers and improves the expectations of the stability of farmland property rights.These conclusions in this paper are conducive to not only understanding the operational mechanisms of farmland transfer markets in the context of informatization, but also increasing the number of agricultural income, which achieves the goals of common prosperity.
