本文将赶超经济最优增长模型从生产函数切换扩展至经济结构切换，构建含内生结构转型的Ramsey模型，揭示市场机制下结构转型与资源配置促进经济发展的机理。
摘要：
本文将Xing（2023abcd）关于赶超经济体的最优增长模型从生产函数切换的情形扩展到经济结构切换的情形，论述了一国如何通过内生结构转型和市场机制下的有效资源配置来发展经济。为此，本文首先从文献中归纳出经济结构的三个属性，即结构性、持续性和可转换性，并讨论它们对经济建模方法的启示。随后，在共同知识假设下，本文扩展了Xing（2023a）基于生产函数切换的最优增长模型，考虑了一个具有内生结构转型的扩展Ramsey模型，其中社会计划者在资源约束下选择最优产业结构、所选结构下的资源配置以及消费，以最大化代表性家庭的总效用。接着，本文建立了静态、动态和切换均衡的数学基础。随后，Ramsey增长模型及其均衡被扩展到包含层级生产、技术采用与创新、基础设施以及经济和政治制度等复杂经济结构的经济体。最后，本文简要讨论了所提方法在其他场景经济发展问题中的应用。
英文摘要：
This paper extends Xing's (2023abcd) optimal growth models of catching-up economies from the case of production function switching to that of economic structure switching and argues how a country develops its economy by endogenous structural transformation and efficient resource allocation in a market mechanism. To achieve this goal, the paper first summarizes three attributes of economic structures from the literature, namely, structurality, durationality, and transformality, and discuss their implications for methods of economic modeling. Then, with the common knowledge assumption, the paper extends Xing's (2023a) optimal growth model that is based on production function switching and considers an extended Ramsey model with endogenous structural transformation in which the social planner chooses the optimal industrial structure, recource allocation with the chosen structure, and consumption to maximize the representative household's total utility subject to the resource constraint. The paper next establishes the mathematical underpinning of the static, dynamic, and switching equilibria. The Ramsey growth model and its equilibria are then extended to economies with complicated economic structures consisting of hierarchical production, technology adoption and innovation, infrastructure, and economic and political institutions. The paper concludes with a brief discussion of applications of the proposed methodology to economic development problems in other scenarios.
