一、资本积累与经济发展资本积累是经济发展理论中的一个古老课题。根据经济发展的二元结构论,经济发展的本质在于采用新技术的现代部门在经济体系中的相对扩展。由于现代部门主要使用资本,故其生产的扩大以资本的迅速积累为前提。因此,资本积累不仅是经济发展的必要条件,也是经济发展的重要内容,并构成早期发展经济学关注的中心课题。著名的哈罗德—多马模型即在理论上以非常简明的方式表述了资本积累同经济增长的密切关系。根据这一模型,一个既 First, the accumulation of capital and economic development Capital accumulation is an ancient issue in the theory of economic development. According to the dual structure of economic development, the essence of economic development lies in the relative expansion of the modern sector adopting new technologies in the economic system. Since modern departments mainly use capital, the expansion of their production is premised on the rapid accumulation of capital. Therefore, the accumulation of capital is not only a necessary condition for economic development, but also an important part of economic development, and constitutes the central issue of early development economics. The well-known Harold-Toma model states in a very concise way the close relationship between capital accumulation and economic growth in theory. According to this model, one is both
