区域人力资本配置、科技创新对经济增长的作用机理研究

随着经济全球化和知识经济时代的到来,区域人力资本配置通过影响科技创新能力对经济增长的作用正在日益凸显。文章遵循这三者之间的作用机理着重分析两个方面:一方面,从不同类型人力资本对科技创新作用不同的角度出发,优化区域人力资本配置,促进区域人力资本结构优化,进而提升区域科技创新能力;另一方面,科技创新的内在效应、科技创新推动产业结构优化、科技创新加速知识积累共同作用于区域经济持续快速增长。     

熟练劳动力跨国移民、知识结构与经济增长

熟练劳动力跨国移民对于发展中国家人力资本投资的激励效应近年来被许多文献所强调,不过这些文献都忽略了这种激励效应对于人力资本结构的影响。本文通过区分人力资本的类型,构建了一个基于技术进步、知识结构和经济增长关系的模型,分析了熟练劳动力跨国移民对于移出国人力资本积累及经济增长的影响。分析显示,不同发展阶段的国家需要不同知识结构的人力资本,跨国移民的经济影响取决于移出国所处的阶段。在技术模仿阶段,跨国移民的激励效应会扭曲移出国人力资本积累的结构,从而延缓经济增长。只有到了技术创新阶段,这种激励效应对人力资本积累的扭曲才会消失。另外,目标国对熟练劳动力的移民"门槛"政策,会加重移出国人力资本积累的扭曲,进一步延缓其经济增长。     

公共政策、要素积累与经济增长——港台的经验

我们认为公共政策是通过影响经济增长的源泉来促进经济增长的。本文通过比较研究香港和台湾在其快速增长的年代里的政策实践，来分析不同的公共政策对于物质资本、人力资本和劳动这三种投入要素积累的作用，并试图得到一些经验性的结论。     

Does international knowledge spillover always lead to a positive trickle down?

This paper demonstrates the negative effects of positive international knowledge spillovers on economic growth. In other words, we obtain the possibility that educational investment for human capital is crowded out under global economic growth. To this end, we assume the phenomenon of international knowledge spillover, effects of population growth on human capital accumulation, and non-unity intertemporal elasticity of substitution in an endogenous growth model along the lines developed by Arnold. This model comprises R&D activities along the lines proposed by Jones and human capital accumulation along the lines proposed by Uzawa and Lucas. The results show that even if international spillover increases, low-growth traps without human capital investment emerge in some cases, for example, an economy with a large intertemporal elasticity of substitution and a high population growth rate.     

国际人口迁移、信贷约束与人力资本积累

本文以收入不平等与经济增长的关系为基础,在信贷市场不完全的条件下,进一步考察了熟练劳动力跨国迁移对发展中国家人力资本积累及经济增长的影响。分析显示,基于跨国移民的"教育激励"效应对发展中国家的人力资本积累及经济增长的影响在短期和长期存在差异。短期中,基于跨国移民的"教育激励"效应会减缓"人才流失"效应对发展中国家人力资本积累及经济增长的负面影响,甚至可能会提高发展中国家熟练劳动力的比重,从而促进人均收入水平的提高。长期中,当代际转移收敛于稳态水平时,国际人口迁移不再具有"教育激励"效应,而国际人口迁移的"人才流失"效应则会继续损害人力资本积累,从而对发展中国家的人均收入产生负面影响。     

Human capital and economic growth in Spain, 1850–2000

We investigate human capital accumulation in Spain using income- and education-based alternative approaches. We, then, assess human capital impact on labor productivity growth and discuss the implications of its alternative measures for TFP growth. Trends in human capital are similar with either measure but the skill-premium approach fits better Spanish historical experience. As education is a high income elastic good, human capital growth computed with the education-based approach seems upward biased for the recent past. Human capital provided a positive albeit small contribution to labor productivity growth facilitating technological innovation.     

贸易溢出、人力资本与经济增长--基于中国数据的经验分析

按照Muzumdar和Baldwin的观点,贸易通过促进资本积累来促进进口国的经济增长,而根据Helpman等人的观点,贸易通过其内生的技术溢出对经济增长的影响更为持久,而技术溢出的效果则与贸易结构相关,并且需要一定的人力资本存量相结合,通过结合中国的数据分析发现:人力资本结构和分布状况对贸易溢出产生显著影响,人力资本水平的提高将增加贸易对经济增长的贡献,即贸易通过人力资本发生的技术溢出对经济增长会产生持久影响。     

国家创新能力的助学贷款支持系统构建

技术创新需要人力资本的投入,人力资本主要来源于正规学校教育和“干中学”。随着市场经济的发展,正规学校教育和入职后的培训都需要支付一定的学费,这导致了一部分贫困学生无法顺利完成学业和进行再培训,在一定程度上影响了人力资本的积累,进而制约了技术创新的开展。对助学贷款、人力资本积累与技术创新的关系进行了理论分析,得出结论：助学贷款通过促进人力资本积累,对一国的技术创新有推动作用。最后,对我国技术创新的助学贷款支持系统构建提出了建议。     

人口红利贡献被高估了吗?——基于人力资本积累视角的研究

人口红利下降被认为是新常态下中国面临的重大挑战,然而劳动投入不仅包含劳动数量,还包含劳动质量,分别对应于人口红利与人力资本。由于在测量上忽视了高速城市化对人力资本积累的积极影响,在机制上忽视了人口红利和人力资本分布趋同的叠加影响,容易造成人口红利贡献高估且人口资本贡献低估。文章从人口迁移视角出发,参考拉姆齐无限期界模型建立人力资本积累方程,将城市化对人力资本积累的积极作用纳入分析,得出转换效应、迁移效应和共振效应,阐明人口红利和人力资本空间分布趋同的微观机制,得到检验人口红利和人力资本对经济增长贡献的一致性框架。以2013-2016年272个样本城市进行计量检验：固定效应回归分析和内生性检验表明人口红利和人力资本的增长弹性排序不确定,中介效应检验表明人力资本的增长贡献超过人口红利,分组检验进一步证实人力资本贡献超过人口红利,且存在相互叠加共同影响城市经济增长的共振效应。结论表明,若充分考虑城市化对人力资本的积极影响,则人口红利的贡献确实被高估,而人力资本的贡献被低估。由此得出政策建议,应持续推进城市化高质量发展,加速人力资本积累,构筑劳动质量替代劳动数量的机制,以更好地应对新常态下人口红利下降的负面冲击。     

Losing the future: Household wealth from urban housing demolition and children's human capital in China

Some literature observes the negative but not very significant effect of household wealth growth on children's educational outcomes. This surprising finding is not easily reconciled with the traditional explanation that relaxed economic constraints caused by wealth growth can promote human capital accumulation. This paper proposes an alternative explanation for the causal relationship between wealth growth and human capital, which could be negative: individuals tend to reduce human capital investment following the decline in their labor supply induced by wealth growth, given that investing in human capital is mainly for employment competitiveness. This explanation is supported by evidence from the case of urban housing demolition in China, in which affected households could obtain substantial wealth growth by considerable demolition compensation thanks to the real estate boom in China. Specifically, using two nationally representative datasets, we find that Chinese households that have experienced demolition relatively have more wealth, less labor supply, lower propensity to accumulate children's human capital, and consequently, have children with lower educational achievement. These results suggest that China's economy may be losing its momentum because of the decline in labor supply and human capital accumulation brought about by the ongoing large-scale urban housing demolition.     

Social protection,redistribution and economic growth

Social protection has conventionally been associated with redistribution and equity. This paper examines the effects of different types of social protection on economic growth. It looks at the possible effects on human capital formation, on physical investment and innovation, on the local economy and on the macroeconomy, discusses these effects in theory and reviews empirical evidence of such effects. It considers the widely varying impacts that different types of social protection can have on the distribution of incomes and on economic growth. The paper concludes that, in analysing, assessing and planning social protection, it is crucially important to consider the potential drawbacks – and the benefits.     

Trade and Convergence: A Dynamic Panel Data Approach

The objective of this paper is to provide, theoretically and empirically, an interpretation of comovement between the scale of an economy and its growth rate. I paid special attention to human capital accumulation and international trade environment and emphasized their spillover effects on growth and convergence among countries. 1 employed a technique using a cross-sectional and time series panel. The estimations in my empirical models were done using the nonlinear least-squares method in which I applied a dynamic procedure for an economy along its balanced growth path. I arrived at mixed results. The empirical results show that international spillover effects of human capital accumulation and intermediate goods production have positive and significant effects on the growth process of a nation. The national level of human capital, however, has negative and insignificant effects on this process.

人力资本投资结构及其对经济增长的影响——基于扩展MRW模型的内生增长理论与实证研究

本文针对已有的关于人力资本投资的理论研究往往只关注人力资本投资数量而忽视人力投资结构研究的现状，把教育和健康看作两种资本，分析了人力资本投资的具体构成形式。假设人力资本由教育资本和健康资本按照Cobb—Douglas生产技术形式组合生成。通过扩展Mankiw、Romer和Weil（1992）模型（简称MRW模型），构建了一个新的内生经济增长模型。理论分析结果表明：人力资本投资结构制约着经济增长，人力资本积累和存量都对经济产生重要影响。最后文章以理论分析为基础构建计量经济模型，利用1978—2004年中国29个省、市、自治区的面板数据实证分析了人力资本的积累和存量以及教育资本和健康资本对中国经济增长的影响。实证结果表明较好地支持了本文的理论拓展分析。     

STABILIZATION POLICY, LEARNING-BY-DOING, AND ECONOMIC GROWTH

This paper shows that fiscal policy, when used for stabilizationpurposes, can have a positive effect on the economy's growth,on human capital accumulation, and on welfare. We introducestochastic productivity shocks into a model in which productivityis augmented through learning-by-doing If future benefits oflearning-by-doing are not fully internalized by workers, thenrecessions are periods in which opportunities for acquiringexperience are foregone. We identify configurations of disturbancesand other parameters for which a countercyclical policy maximizesgrowth and welfare.     

Firm-level human capital and innovation: Evidence from China

This paper examines the role of human capital in firms' innovation. Based on a World Bank survey of manufacturing firms in China, we use two firm-level datasets: one from large metropolitan cities, and one from mid-sized cities. Patents are used as an indicator of innovation. The human capital indicators we use include the number of highly educated workers, the general manager's education and tenure, and the management team's education and age. We use the Negative Binomial and Instrumental Variables estimators to estimate patent production function models that are augmented by our human capital variables. We also use the zero-inflated Negative Binomial model to examine the likelihood of innovation. We find that the human capital indicators play an important role in influencing patenting, and that some of the human capital variables appear to have a greater impact on patenting in mid-sized cities. Our human capital estimates are obtained after controlling for firms' R&D, size, market share, age, and foreign ownership, as well as fixed effects to control for industry-specific characteristics, and firms' location and geography.     

政府财政政策对经济增长的影响——基于一个资本积累与创新相互作用模型的分析

政府财政政策对经济增长和社会福利的影响,是经济增长理论和宏观公共财政理论研究的重点,已经有大量的研究。本文在一个资本积累与创新相互作用的框架下内生化劳动力供给,假设政府通过征收平滑的收入税为公共支出融资,并且将政府公共支出区分为资本性支出和研发性支出,从而考察了税收和财政支出结构对经济增长的影响及其作用机制。研究发现,当政府通过征收收入税为生产性公共支出融资时,收入税税率与经济增长率之间存在一个倒U形的关系,从而回到了Barro(1990)的结论,尽管本文强调的政府财政政策作用于经济增长的机制与Barro(1990)差别较大;在基准经济(benchmark economy)的参数环境下,财政支出结构与经济增长率之间存在一个倒U型关系,从而经济中存在一个最优的财政支出结构。     

Health investment,physical capital accumulation,and economic growth

This paper analyzes the effect of health investment, and hence of health capital, on physical capital accumulation and long-run economic growth in an extended Ramsey model with an Arrow–Romer production function and a Grossman (1972) utility function. The paper concludes that economic growth is related to both the health growth rate and the health level. While growth in health capital always facilitates economic growth, the gross effect of health level on the rate of economic growth depends on how it affects physical capital accumulation. If the negative effect of health on economic growth through its influence on physical capital accumulation is not taken into consideration, then health level has a positive effect on the rate of economic growth by improving the efficiency of labor production. However, since health investment may crowd out physical capital investment and thus influence physical capital accumulation, excessive investment in health may have a negative effect on economic growth. Empirical tests of these theoretical hypotheses using panel data from individual provinces of China produce results that are consistent with our theoretical conclusions.     

Does Schooling Promote Economic Growth?

Abstract: This paper revisits the debate on schooling and economic growth with particular reference to the case of sub‐Saharan Africa. Following the endogenous growth model developed by Lucas (1988) that considers human capital as one factor of production and schooling as a means of human capital accumulation, two results of schooling are explicitly stated: accumulation of privately owned and publicly owned human capital. By developing a growth estimating equation containing these two types of schooling results from the model and confronting it with empirical data, the hypothesis that schooling has got growth effect is tested. The analytic result suggests that in the indicated economies, for the period covered by the study (1966–2000), schooling that leads to accumulation of publicly owned human capital is associated with per capita income growth. Likewise, the analysis provides supporting evidence for the argument that primary schooling level is more associated with growth than other levels of schooling.     

技术进步、效率变化、资本积累与我国地区服务业发展

本文用非参数生产前沿方法将我国1978—2007年服务业劳均产出增长分解为效率变化、技术进步和资本积累的贡献三个部分,并用方差分解方法估算了各部分对地区服务业劳均产出增长率差异的贡献,然后采用核密度分布方法分析了上述三个部分对地区服务业发展的影响。研究发现：（1）技术进步是促进各地区服务业增长的重要因素,其作用随资本积累的提高呈上升趋势;（2）效率虽然对服务业经济增长的平均贡献较小,但却是各地区服务业增长率差异的主要原因;（3）资本积累在不同时期对地区服务业增长的贡献差别很大,其作用随时间发展呈上升趋势。
