ABSTRACT
The agricultural sector's supply-side reform is fundamental to ensuring food security and social stability. This paper uses a comprehensive analysis method to reflect on China's agricultural reform from 1970 to 2020. We observe that China's agriculture made significant progress before 2020 due to preferential policies and demographic dividends. This production-oriented mode has led to the co-existence of overstocking, the rapid growth of imports, and ecological degradation. A follow-up survey acknowledged that rural complex is a comprehensive social network with substantial radiant effect involving government-sponsored projects, sector-specific programs, corporate and societal assistance. The sustainable development of the rural complex lies in industrial planning, system restructuring, and institutional arrangement. Therefore, this article anchors its system structure under the ESG principle and green development philosophy. It diversifies the agro-economy to advance digitalization and de-carbonization of the rural economy.
