摘要
本文从生产函数演变的视角探讨增长理论的变迁,找出各种理论在生产函数形式上的异同,同时指明其背后隐含的经济意义和内在逻辑上的重大差别。从资本积累、外生技术进步到内生增长模型,本文剖析了这些模型是怎样建立起一般均衡的,并厘清了内生增长的决定因素。我们认为增长理论的未来发展不能局限于生产函数方面的考量,需转向"算法"(Algorithm)模型的开拓。在计算技术大幅提升的当下,我们应当加大力度开发"Agent-Based Model"(ABM)、"Agent-Based Computational Economics"(ACE)去模拟经济个体在不同政策环境和规章制度下的决策,探讨政策和体制变化给经济增长带来的影响。"算法"模型的第一目标是在有限的现有成果基础上,建立起相对小型但具有拓展潜力的标准化增长理论模型,逐渐形成新的研究范式,其创新虽有难度,但成果是令人期盼的。
This paper examines the historical development of the economic growth theory from the perspective of the evolution of production functions.We identify the distinctions and commonalities in the production functions used across theories.We also point out the major differences in their underlying economic meanings and intrinsic logic.Starting with capital accumulation and exogeneous technological progress and then moving to endogenous growth theory,this paper analyzes how these models establish a general equilibrium and clarifies the determinants of endogenous growth.For future development of the growth theory,we think it unwise to limit ourselves to the domain of production function;rather,we need to venture into Algorithm-based models.With great improvements of computing technology,we should put efforts into developing'Agent-Based Models'(ABM)and'Agent-Based Computational Economics'(ACE)to stimulate economic individuals’decision-making under different policy environments and regulations,and study the impact of policy and institutional changes on economic growth.The first goal of Algorithm-based models is to build a proto-type theoretical growth model based on the existing research findings and gradually form a new research paradigm.The initial steps are difficult but the prospect is great with much to look forward to.
