An Analysis of the Endogenous Factors for the Growth of Developing Countries

在本研究中，我们对发展中国家的内生增长因素进行了理论和实证分析。我们首先修正了新古典增长模型，允许通过国内储蓄率和人力资本投资等内生因素来解释经济增长。此外，鉴于用于物质和人力投资的总资金往往是有限的，我们扩展了框架，以允许在物质和人力资本投资之间进行权衡。基于该模型的假设，我们进行了实证分析。1994年，我们收集了68个国家1965- 1988年期间的数据，并审查了增长的内生因素。1995年，我们详细阐述了我们的数据集，并收集了78个国家1980- 1990年期间的数据。根据这些数据，我们检查了数据集的同质性，并使用统计程序将样本国家细分为几组。更多的发现包括：(1)发展中国家的经济结构是多样化的，我们在进行实证分析时不应该将它们捆绑在一起；(2)物质资本投资对经济增长有正向影响，而人力资本投资对经济增长没有正向影响。积极影响仅限于中等收入和高收入国家；(3)在中等收入国家，人力资本投资对经济增长的影响超过实物资本投资，投资资金转向人力投资将促进经济更快增长；等。总结这些结果的论文被《亚洲经济杂志》有条件地接受，即将出版。此外，一位研究合作者对经济增长、进口和出口之间的因果关系进行了分析，并将结果总结在题为“亚洲新兴经济体出口与增长之间的因果关系：进一步的实证证据”的论文中。少

In this research, we carried out a theoretical and empirical analysis of the endogenous factors of growth for the developing countries. We have first revised the neoclassical growth models allow an explanation of economic growth by endogenous factors such as domestic saving rate and human capital investment. In addition, in view of the fact that the total funds for physical and human investments are often limited, we extended the framework to allow for the tradeoff between physical and human capital investments. Based on the hypotheses derived from this model, we have carried out empirical analyzes. In 1994, we have gathered date for 68 countries for the period 1965-88, and examined the endogenous factors of growth. In 1995, we have elaborated upon our data set and collected data for 78 countries for the period 1980-90. Based on this data, we have examined the homogeneity of the data set and used statistical procedure to subdivide the sample countries into several groups. The major fin … More dings include : (1)developing countries are diverse in their economic structure, so that we should not bundle them in one when carrying out empirical analysis ; (2) physical capital investment affects growth positively in every group of countries, but human capital inverstment does not affect growth positively in the less advanced countries. The positive effect is limited to middle-income and high-income countries ; (3)in middle-income countries, the effect of human capital investment on growth exceeds that of the physical capital investment, so that shifting investment funds toward human investment will enhance a faster economic growth ; etc. The paper summarizing these results are conditionally accepted in the Asian Economic Journal and is forthcoming. In addition, an analysis of the causal relationship between economic growth, imports and exports has been undertaken by a research collaborator and the results are summarized in a paper titled "Causality between Exports and Growth in Asian NICs : Further Empirical Evidences."
