The post-resettlement support for reservoir immigrants plays a critical role in consolidating the achievements of poverty alleviation and advancing the rural revitalization strategy. With the shift in focus towards industrial support in the current post-resettlement assistance efforts

most research has tended to summarize local experiences with specific types of industrial support projects. However

there is a relative lack of systematic integration when it comes to addressing the various elements of industrial support. This paper

based on the theory of dynamic mechanisms

explores the internal and external challenges faced in empowering immigrants development through industrial support projects

and proposes strategies to address these challenges. The study finds that industrial support projects often suffer from insufficient endogenous growth capacity

a lack of exogenous support capacity

and a deficiency in internal-external synergies. To achieve the sustainable development of supporting industries in the later stages

it is essential to approach this challenge from three dimensions: activating internal driving forces

strengthening external support

and fostering synergy between the internal and external drivers. This will enhance the self-driving capabilities and innovation of immigrants

strengthen policy and financial support

improve the mechanism for benefit-sharing

and open up diverse channels for participation

thus ensuring the effective coupling of subjects

forces

and motivations.
