Grassroots Innovation and Policy Evolution: The Agricultural Production Responsibility System in Shangtang, China

This study examines the transformative effects of the household contract responsibility system on agricultural productivity, income levels, labor participation, and rural development in Shangtang Community, Jiangsu Province, during China's early rural reforms from 1974 to 1984. Utilizing a qualitative case study approach grounded in extensive archival research and policy document analysis, the study reconstructs the reform trajectory and assesses its impacts through both qualitative insights and key quantitative indicators such as grain output, labor participation, and income growth. Findings reveal that following the reform, grain production nearly doubled, per capita income increased more than fivefold, and labor participation surged significantly, contributing to rural revitalization and economic resilience. The research highlights the critical role of institutional innovation and grassroots leadership in driving sustainable land management and rural socioeconomic transformation. These outcomes validate the household contract responsibility system as an effective policy model and offer lessons for contemporary sustainable rural development strategies.
