Abstract: Ge Heping and others from the Yangtze River Industrial Development Research Institute (Nanjing University) point out that building a unified national market is a crucial foundation and an inherent requirement for establishing a new development paradigm. Currently, some regions still exhibit phenomena such as self-protection and the creation of small, closed loops in their investment promotion efforts. This leads to reduced efficiency in resource allocation and intensified regional market fragmentation, preventing enterprises from fully leveraging economies of scale and undermining the effectiveness of efforts to build a unified market system. At present, local investment promotion efforts face challenges such as slow progress in institutional substitution and difficulties in implementing unified rules; performance evaluations are overly focused on short-term results, making it difficult to coordinate policies; there is insufficient integration among factor markets, limiting the effectiveness of platforms; and the foundation for regional collaboration is weak, with inadequate cross-regional institutional development. Therefore, it is recommended that local investment promotion departments improve the unified system of rules and refine the institutional substitution mechanism; emphasize performance evaluation as a guiding principle and strengthen policy coordination capabilities; deepen reforms in factor markets and build a unified digital platform; and enhance regional collaboration and cooperation while innovating Party-building-driven investment promotion models.
