中文摘要：

发展中大国在人力资本水平远低于发达国家的现实条件下,因其异质性人力资本与多元化的产业结构、物质资本投资、技术水平之间的耦合即适应性而形成一种比较优势。这从理论上较好地解释了发展中大国尽管人力资本水平较低,但仍能较好地促进经济增长这一假说。运用耦合度模型的实证研究支持了这一理论假说。其政策含义十分明显：发展中国家在不断加大人力资本投资的同时,更应该注重增强其人力资本对多元化的产业结构、物质资本投资与技术水平的适应性,以＂扬长避短＂,从而促进经济持续快速协调发展。

英文摘要：

This paper defines human capital’s comprehensive advantages of large developing country,and explains its mechanism of action based on the dynamic coupling relation between heterogeneous human capital and multiple industrial structure,physical capital investment,and technical level,which provides good explanation for the hypothesis： although the level of human capital is relative low,the large developing country’s economy grows fast.The empirical study supports this theoretical hypothesis by using coupling model.Its policy implement is obvious： it should pay more attention to enhance its human capital’s adaptability to multiple industrial structure,physical capital investment,and technical level when developing country strengthen human capital investment,so as to make full use of its advantages and avoid its disadvantages,and promote the sustained,rapid and coordinated economic development.
