Abstract: Regional Economic Law, as a novel legal phenomenon, constitutes a systematic project within the development of the rule of law. Its factual and normative descriptions involve numerous fundamental categories awaiting further elaboration. Among these, rights-as a foundational category in legal philosophy-serve as the logical starting point for constructing the ontological framework of Regional Economic Law. The spectrum of regional rights within regional economic law exhibits a hierarchical structure. This encompasses foundational rights such as the regional right to development and the regional property right, alongside fundamental rights like the regional right to development safeguards. Derivative rights, including regional economic autonomy and inter-regional interest compensation rights, constitute auxiliary and remedial capacities. The regional right to development and specific regional rights fulfil distinct roles within the theoretical framework of regional economic law; their logical articulation represents the unification of factual and normative dimensions of rights. The former constitutes the origin and basis for the emergence of regional economic law, delineating its legal value pursuits and institutional objectives; the latter represents the transformation of primordial rights into legally established instrumental or means-oriented rights. These constitute the concrete manifestations of the regional right to development within regional economic law, embodying the normative practice of regional economic law rights and possessing a practical-theoretical character.
