本文在分析我国城乡收入差距对投资和经济增长影响的基础上,建立了一个能考察经济增长、城乡收入差距与投资互动关系的联立方程组模型,用2SLS和3SLS方法估计结果表明,劳动者受教育程度和人均收入水平的提高既能促进经济增长,又能缩小城乡收入差距。因此,降低固定资产投资在GDP中所占比重、转变产业结构是实现我国经济增长效率和公平双目标的有效途径。
Based on the analysis of the impact of urban-rural income disparity on investment and economic growth in our country, this paper establishes a simultaneous equations model that can examine the interaction between economic growth, urban-rural income disparity and investment. The results of 2SLS and 3SLS show that laborers The level of education and per capita income can both promote economic growth and narrow the income gap between urban and rural areas. Therefore, reducing the proportion of fixed asset investment in GDP and transforming the industrial structure are effective ways to achieve the dual goal of economic efficiency and fairness in our country.
