二元经济的增长模型分析

Research on the Growth Model of Dual Economy

现有的经济增长理论通常认为资本积累与技术进步无关或负相关,但事实并非如此。构建的二元经济的资本积累方程发现,资本积累是现代部门技术进步的增函数。在此基础上,展开二元经济的稳态分析和增长分析,从而全面地构建了新的二元经济增长模型。该模型除了强调资本积累对储蓄率和技术进步的依赖之外,还强调技术进步、劳动力转移和资本产出比等因素对经济增长的约束。二元经济增长模型可视为新古典增长模型的广义形式,它真正体现了“科学技术是第一生产力”。

The existing economic growth theories usually emphasize that the capital accumulation has irrelevant or negatively related to technological progress,which is not the truth.The paper builds up the capital accumulation equation of dual economy at first,and finds that capital accumulation is an increasing function of technological progress in modern sectors.Based on this,the paper unfolds the steady analysis and growth analysis of dual economy,and establishes a new growth model of dual economy comprehensively.The model not only emphasizes on the dependence of capital accumulation on savings rate and technological progress,but also focuses on the constraints of economic growth on factors such as technological progress,labor transfer,and capital-output ratio.The growth model of dual economic can be regarded as the generalized form of the neoclassical growth model,which really embodies that“science and technology are the primary productive forces”.
