Practical Mechanisms and Policy Optimization of Migrant Workers’ Return-to-Hometown Entrepreneurship Driving Urban-Rural Integrated Development—An Empirical Study Based on 2028 Entrepreneurial Entities in Renshou County, Meishan City

Migrant workers' return-to-hometown entrepreneurship constitutes a vital pathway for driving urban-rural integrated development.Based on survey data from 2028 entrepreneurial entities in Renshou County, Meishan City, this paper empirically analyzes the characteristics, dilemmas, practical mechanisms, and policy optimization of return-to-hometown entrepreneurship.The findings reveal that the entrepreneurial subjects are predominantly male with junior or senior high school education levels, generally facing common dilemmas such as capital shortages, insufficient policy outreach, and low organizational capacity.Entrepreneurship drives urban-rural integration through threefold mechanisms: the extension and restructuring of industrial chains, which retain valueadded benefits in rural areas; the return of entrepreneurial subjects, which absorbs local employment and revitalizes social networks; and land transfer alongside the reverse flow of capital and technology, which enables two-way factor mobility.Policy optimization should shift from "universal support" to "targeted empowerment", by establishing a risk-sharing financial system, setting up one-stop service windows, and implementing differentiated industrial guidance governance models.This study provides empirical evidence and decision-making references for western counties to improve return-to-hometown entrepreneurship policies and promote urban-rural integrated development.
