教育体系、收入分布与经济增长

本文使用一个包含物质资本与人力资本积累的世代交叠模型,研究不同的教育体系对经济增长的影响.我们发现,在公立教育体系下,最优的教育投资水平高于私立教育体系,收入差异也将会比在私立教育体系下下降得更快.因此,与私立教育体系相比,公立教育体系更有利于人力资本积累,在公立教育体系下一个国家将会有更高的经济增长率与更为平等的收入分布.     

经济增长与收入分配间的相互作用机制及其实证分析——基于有约束条件的VECM

本文提出经济增长与收入分配间的相互作用机制,在这基础上利用带有两个协整的VECM对该机制进行实证.结果表明:改革开放以来我国收入分配通过降低物质资本和人力资本效力影响经济增长,且金融发展程度有助于缓解收入分配对经济增长这种的负作用;经济增长通过物质资本途径扩大收入差距,通过人力资本途径缩小收入差距.     

中国经济增长绩效分析

经济增长理论的最新发展揭示了这样一个规律:一个国家长期经济增长的决定因素或源泉是知识、人力资本积累和制度这样一些内生因素,而不是资源数量和人口数量这样一些外生因素。也就是说,长期经济增长率的大部分不是来自劳动和物质资本数量的增加,而是来自知识、人力资本积累水平的提高以及有效率的制度。这对研究我国的经济增长现实,解释我国的经济增长源泉富有启发意义。     

区域人力资本差异成因分析

一、区域人力资本差异西方新增长理论将人力资本纳入到了经济增长模型当中,认为专业化的知识和人力资本积累内生了技术进步,而知识的外溢性或人力资本的外部性保证了技术进步,使经济范围的规模收益递增,从而使经济长期持续增长。人力资本理论的创始人之一舒尔茨也论证了人力资本投资是经济增长的主要源泉,经济发展过程中人力资本投资收益率要高于物质资本投资收益率,而且人力资本较快地增长对于收入均等化和国际经济关系改善都起着很大的作用。区域经济实力直接取决于区域拥有的物质资本和人力资本,但在知识经济时代,人力资本对经济增长的贡…     

珠三角地区资本结构与劳资关系的实证研究

根据资本-劳动替代的“拐点论”,经济发展的初期总是伴随着物质资本的积累,物质资本将在相当长的时期占据经济增长的主导地位;由于资本劳动的边际替代率递减,当物质资本积累处于一定阶段,产生对人力资本更多需求,人力资本则成为这个时期的主要资本;只有在经济持续发展,政治文明发展到一定程度,信任、规范、网络和社会公德等社会资本才有可能成为推动经济发展的主导力量。珠三角地区城市的劳资关系在近30年均处于下降趋势,物质资本总体处于上升趋势,人力资本意义上的劳动力尤其是高层次高素质的劳动力较缺乏;社会资本可以显著的促进物质资本和人力资本的积累,物质资本水平的提高并不必然产生人力资本积累和社会资本积累的结果,人力资本积累也不必然促进社会资本的发展。需要转变经济发展方式,为资本演化创造物质条件,促进人力资本和社会资本积累,并在企业管理层面上促进合作型劳资关系的形成。     

非线性增长与经济增长动力转换

采用时变马尔科夫区制转换模型,分析了不同投入要素在不同经济增长阶段对经济增长贡献的差异,以及影响经济在不同区制之间跃迁的关键因素。研究发现:在三类经济增速区间内,人力资本投入对经济增长的拉动效应最强,在推动经济从中速增长向高速增长转移的过程中发挥重要作用;帮助经济跨越"中等收入陷阱"的关键在于提高物质资本和人力资本投资的匹配度,使物质资本和人力资本的流动与产业集聚和城市化发展一致、与技术创新能力提升配合;渐进式转型有利于平滑增长路径,降低向高收入均衡收敛的临界值。     

人力资本、投资结构与内生经济增长

针对已有的内生增长模型忽视物质资本投资对人力资本生产和技术研发影响的现状,文章建立了一个考虑物质资本投资结构和人力资本分配比例的三部门内生经济增长模型。模型推导结果表明：均衡经济增长率与分配到教育部门的人力资本比例和物质资本比例成正比,而与分配到物质生产部门的物质资本比例和分配到研发部门的人力资本数量呈反比。     

干中学、过度投资和R&D对人力资本积累的“侵蚀效应”

R&D的过度投资对人力资本积累具有"侵蚀效应"。本文提出了一个同时内生化技术进步和人力资本积累的经济增长模型,强调了R&D过程中的两种特征,即R&D过程需要人力资本投入和新技术的研发通过干中学获得,并就R&D对人力资本积累的"侵蚀效应"所造成的负外部性进行了分析。通过比较分散经济均衡和集中经济均衡,本文得出结论:垄断加价及其引致的物质资本和人力资本的过度投资与"侵蚀效应"相互交错、共同作用,会在一定程度上降低人力资本的积累率和经济增长率。     

物质资本与人力资本积累的最优规模和结构研究——一个理论分析框架

资本积累是经济增长的重要源泉。本文通过构建一个理论模型,分析了与最优经济增长相对应的最优物质资本和人力资本规模以及二者的比例关系问题。研究结果表明,物质资本和人力资本都存在最优规模,也存在过度积累的可能性;物质资本积累和人力资本积累的最优比例等于两种资本的产出弹性之比。     

影响新疆发展与稳定的深层因素:人力资本短缺

人力资本对经济的推动力远超物质资本,这已被理论研究和世界许多国家的实践反复证明。改革开放30多年来,新疆经济快速发展,积累了较为充裕的物质资本,但人力资本积累远远滞后于物质资本的积累。支撑新疆发展的人力资本严重不足,直接导致经济的活力和持续快速发展的动力不够强劲,新疆与内地经济发展差距日趋扩大。由于人力资本短缺,创业就业能力低下,使得大量劳动力失业,弱势群体增多,给社会稳定带来隐患。加快人力资本积累,才是缩小一切差距的根本,也是强化国家意识、公民意识、维护稳定、促进民族团结的基础,也只有加快人力资本积累,才能确保新疆实现跨越式发展和长治久安。     

Does income inequality hinder economic growth? New evidence using Australian taxation statistics

Using taxation statistics, we first derive consistently defined Gini coefficients for the period 1942–2013 for Australia as a whole as well as its eight states and territories. While income inequality exhibited a downward trend until 1979, it has since been on the rise not only over time, but also across states and territories. We then proceed to examine the effect of inequality on economic growth after controlling for changes arising from investment in physical and human capital using available panel data across all states and territories (1986–2013). We find that inequality adversely affects economic growth with a couple of years delay, an outcome consistent with similar studies undertaken in the United States and Europe. Our findings suggest that policymakers can address rising income inequality by implementing measures that support, and enhance, human capital accumulation given its long-run economic and social benefits.     

Institutions,human capital,and growth: The institutional mechanism

This paper contributes to the debate on the relationship between human capital, institutions, and economic growth. The paper first develops a micro-foundation model linking institutions to human capital. The advantage of our modeling strategy is that the human capital accumulation function is derived from an endogenous process. The theoretical model shows that improvements in the quality of institutions foster human capital accumulation, decrease income inequality and change the historical development path. The paper uses cross-country panel data from 1965 to 2005 to test some of the model's propositions and finds that deep structures or structural institutions – which are very persistent and rooted on the historical development path of an economy – affect long-term economic performance, while political institutions are uncorrelated with productivity and long-term economic growth. The empirical estimates also show that growth of physical and human capital – instead of levels – determines long-run economic growth.     

From Physical to Human Capital Accumulation: Inequality and the Process of Development

This paper develops a growth theory that captures the replacement of physical capital accumulation by human capital accumulation as a prime engine of growth along the process of development. It argues that the positive impact of inequality on the growth process was reversed in this process. In early stages of the Industrial Revolution, when physical capital accumulation was the prime source of growth, inequality stimulated development by channelling resources towards individuals with a higher propensity to save. As human capital emerged as a growth engine, equality alleviated adverse effects of credit constraints on human capital accumulation, stimulating the growth process.     

内生经济增长理论框架下的市场失效与财政政策

内生经济增长理论认为,知识和人力资本的外部效应与创新带来的垄断势力推动经济增长的同时,也会带来非帕雷托最优的经济增长收入分配的不公平,将阻碍经济增长;加快知识和人力资本积累、促进技术进步以及缓解收入分配不公平的财政政策能纠正市场失效,使长期经济增长达到社会最优.     

Human capital distribution, growth and convergence

This paper studies the dynamic relationship between distribution and endogenous growth in an overlapping generations model with accumulation of human and physical capital. It is shown how human capital can determine a relationship between per capita growth rates and inequality in the distribution of income. Family background effects and spillovers in the transmission of human capital generate dynamics in which aggregate variables depend not only on the stock, but also on the distribution of human capital. The evolution of this distribution over time is then characterized under different assumptions on private returns and the form of the externality in the technology for human capital. Conditions for existence, uniqueness and stability of a constant growth equilibrium with a stationary distribution are derived. Increasing returns, idiosyncratic abilities and the possibility of poverty traps are explicitely characterized in a closed form solution of the equilibrium dynamics, showing the role played by technology and preferences parameters.     

收入不平等对经济增长影响的实证研究

采用联立方程分析方法,实证分析了收入不平等对经济增长影响的三种机制,探讨了收入不平等如何通过影响物质资本投资、人力资本投资和居民消费来作用于经济增长。结果表明,从长期看收入不平等的扩大会刺激物质资本投资,但不利于人力资本投资和居民消费增长,收入不平等对经济增长的长期影响为负。因此,从经济发展的角度政府不应容忍收入不平等的过分扩大。     

Scale Effects,Savings and Factor Shares in a Human Capital-based Growth Model with Physical Capital Accumulation

Using a balanced-growth model with physical and human capital accumulation, we analyze quantitatively the long-run effects of changes in the savings rate and in income distribution (i.e. the shares of physical and human capital in income) on investment in skill acquisition, income growth, and the ratio of human to physical capital. In the long run, the ratio of physical to human capital is constant, so that these two factor inputs can grow at the same rate. This rate is a function of the economy's exogenous technological and preference parameters and depends positively on the share of skills invested in human capital formation. We also find that population growth is neither necessary nor conducive to economic growth, that the level of real income depends linearly on the level of human capital and that it is independent of population size.     

要素生产率和要素配置作用下的中国城乡收入差距

根据城乡生产函数差异的特征事实构建了城乡收入差距模型,利用我国各省1997—2009年数据研究城乡劳动力比、固定资产比、人力资本比、农业中间品投入、工业化和第三产业规模对城乡收入差距的影响。结果显示,我国城乡要素生产率与城乡要素配置的差异对城乡收入差距具有决定性作用;城乡劳动力比的增长明显有助于缩小城乡收入差距,而城乡人力资本比、固定资本投入比、农业成本、以及相邻地区间的相关性都导致了城乡收入差距的扩大。缩小城乡差距的重要途径是加快农村劳动力的城市化、增加农村教育投入、提高农业生产率、增加农村的物质资本投入,各省缩小城乡收入差距的努力对邻近省份也会产生积极影响。     

The dynamics of catch-up and skill and technology upgrading in China

This paper accounts for China’s economic growth since 1980 in a unified endogenous growth model in which a sequencing of physical capital accumulation, human capital accumulation and innovation drives the rise in China’s aggregate income. The first stage is characterized by physical capital accumulation. The second stage includes both physical and human capital accumulation, and in the final stage innovation is added to the mix. Model calibrations indicate that the growth model can generate a trajectory that accords well with the different stages of development in China.
