factor input and technical progress and innovation of institutions are some important factors which influence china's long-term economic growth . the increase in factor input and improvement of comprehensive productivity are the direct reason of china's economic growth . institutions are the reason which influence efficient factor input and technical progress, and the reason of the direct reason of china's economic growth 本文研究认为,要素投入的增加固然可带来经济增长,但生产要素资源是有限的,单纯依靠要素投入很难实现经济的持续增长;要素投入、技术进步和制度创新都是影响中国经济长期增长的重要因素;要素投入增加和综合生产率提高是中国经济增长的直接原因,制度是影响要素投入效率、技术进步的原因,是中国经济增长的直接原因之原因。
the 21st century will be an age of knowledge economy and knowledge will become the most fundamental and most efficient factors of all that create wealth . human sources will become the scarcest resources of all the factors of production . it's the most important wealth and source for evolution 21世纪是知识经济时代,知识将成为所创造财富要素中最基本、最有效的生产要素,人力资本成为生产要素中最稀缺的资源,是一个国家最重要的财富基础,也是一个国家发展的重要源泉。
