Home-returning entrepreneurship is an effective approach to achieving the goal of integrational process between urban and rural areas. However， the intention of becoming entrepreneurs remains low among those returning people. While current studies have explored the factors influencing such intention， the unique experiences of entrepreneurs in both urban and rural contexts have received insufficient attention. Grounded on social capital theory and institutional theory， it investigated 393 business talents who migrated from rural areas to cities such as Beijing， Shanghai， Guangzhou， and Nanjing. By combining statistical yearbooks of cities and counties， it analyzed how rural-urban institutional differences influence home-returning entrepreneurship intention. Findings reveal that： urban-rural institutional differences negatively influence home-returning entrepreneurship intention； dual social networks negatively moderate the relationship between institutional differences and home-returning entrepreneurship intention； policy perceptions of returning entrepreneurship enhance this moderating effect. These findings reveal the role of urban and rural system differences in the willingness to start up in the homeland， clarify the key boundary conditions between the two， and provide strong support for government departments to formulate policies that encourage business talent to start up in the homeland.
