从结构角度看中国出口贸易的增长波动

本文基于经济周期理论,借助HP滤波法从总体和结构两个角度分析了中国的出口增长波动,结果表明:中国出口波动中,原料密集型产品出口增长速度最慢,劳动密集型产品出口增长持续性最强;资本密集型产品出口增长扩张收缩能力最强,增长最不稳定;易模仿的研发密集型产品出口增长最快,难模仿的研发密集型产品出口增长速度较快。总出口增长波动和上述五类产品出口增长波动之间存在长期均衡关系。     

三大技术创新主体科技成果与经济增长关系研究

在探讨技术创新主体构成、主体不同研究性质及对应经济效益的基础上,对产学研合作背景下的三大技术创新主体与经济增长关系进行了梳理。基于中国1986-2011年的时间序列数据,采用VAR模型,综合运用格兰杰因果检验、脉冲响应函数和方差分解,对中国不同技术创新主体的科技成果与经济增长进行了动态分析。研究表明,企业科技成果对经济发展成效较好,其次是高校,而科研机构科技成果对经济增长的促进作用比企业和高校小得多。结合中国不同技术创新主体的科技成果产出效应进行实证分析,为不同技术创新主体协同实现科技成果对经济增长的正向影响提出了对策建议。     

技术效率、资本深化与地区差异——基于随机前沿模型的中国地区收敛分析

本文提出了基于随机前沿生产函数的地区增长差异分析框架,将各地区劳均产出差距分解为劳均资本差异、经济规模差异和全要素生产率差异三个部分。利用改革时期的省级数据,本文发现尽管要素投入仍然是中国经济增长的主要源泉,但全要素生产率是造成地区差异的重要原因,在地区劳均产出差异中的贡献份额不断提高,将成为今后中国地区增长差异的主要决定力量。而且,1990年以来中国地区全要素生产率呈现出绝对发散趋势,严重的技术扩散壁垒加剧了体制转轨过程中的“马太效应”,短期内地区差距不会随经济发展而缩小,政府需要通过适当的政策对地区发展进行调节,尤其要促进地区间技术扩散,使各地区更好地分享技术创新和体制创新的成果。     

产业集群生态化运作模式对企业成长的影响

产业集群生态化运作为企业提供了不同于传统集群的生长资源和环境,在生态化运作过程中,集群目标设置、空间结构、种群规模、管理要素与运作机制相辅相成,构成其生态化运作维度。以生态化清洁生产外延、网络协同共生、集群核心企业生产链条延伸3种模式进行生态化运作时,集群运作维度呈现出不同特征,构建了企业成长的不同环境、结构和关系力量,形成集群企业成长的约束条件。基于此,在集群的每一种生态化运作模式下,主导产业和关联产业的企业表现出不同成长状态。     

中国能源消费、碳排放与工业经济增长——一个脱钩理论视角的实证分析

本文利用相对“脱钩”、“复钩”的理论与测度模型,对2000—2009年我国工业经济增长与能源消费和碳排放之间的脱钩关系进行研究。在此基础上,对脱钩评价模型进行扩展,构建了脱钩指数分解模型,对脱钩关系的影响因素作出了更为深入的分析,并指出未来工业脱钩发展措施的重点方向是在进一步提升能效技术的基础上,着力推进工业产业结构升级的步伐,提升新型低碳能源的结构比重,改善能源的生产和消费结构。     

Growth and value hybrid valuation model based on mean reversion

This article proposes a novel valuation model, growth and value hybrid model, to estimate the stock price. This proposed model combines the essence of the asset-based approach, the income-based approach, and the principle of mean reversion to develop the theoretical closed-form formula consisting of three coefficients: value coefficient, value support coefficient and growth coefficient. Regression analysis is employed to fit market data to determine these coefficients. Moreover, this study proposes the double sorting method to build the quantile regression models of the formula to estimate the stock price at a specific quantile. The results show that the predictive capability of the hybrid valuation model is superior to the model without using value support coefficient, which supports the assumption that the PBR is not associated with the ROE when the ROE is less than a threshold. In different time periods of the stock market, no significant difference exists on the value support coefficient. However, the variations of the value coefficient and the growth coefficient are significant.     

R&D,public innovation policy,and productivity: The case of danish manufacturing

The purpose of this paper is to investigate the relationship between private R&D, public innovation support transferred to the private sector, and productivity in Danish manufacturing. Two main conclusions are established. First, public innovation support has a positive and significant effect on private R&D expenditures with an estimated elasticity of 0.062. Second, the indirect effect on productivity from public innovation support is reflected in a positive point estimate which is found to be robust to different specifications of R&D capital.     

Trade, investment and growth: nexus, analysis and prognosis

Patterns of causation between income, export, import and investment growth for 39 developing countries are examined using model selection techniques which are based on ex ante predictive ability criteria to identify the best predictive model for each country. In particular, we look at the incidence of causation and reverse causation between various economic variables which are commonly believed to lead economic growth and find that there is less reverse causation from income to these variables than previously thought. We also construct an index of global business cycle conditions and find that models of countries with high trade exposure, growth rates and investment rates tend to gain in predictive ability from the addition of this variable.     

Growth and welfare effects of business cycles in economies with idiosyncratic human capital risk

This paper uses a tractable macroeconomic model with idiosyncratic human capital risk and incomplete markets to analyze the growth and welfare effects of business cycles. The analysis is based on the assumption that the elimination of business cycles eliminates the variation in idiosyncratic risk. The paper shows that a reduction in the variation in idiosyncratic risk decreases the ratio of physical to human capital and increases the total investment return and welfare. If the degree of risk aversion is less than or equal to one, then economic growth is enhanced. This paper also provides a quantitative assessment of the macroeconomic effects of business cycles based on a calibrated version of the model. Even for relatively small degrees of risk aversion (around one) the model implies that the elimination of business cycles has substantial effects on investment in physical and human capital, economic growth, and welfare.     

晋升激励与创业板上市公司创新绩效

选用全部创业板上市公司为研究样本,探讨了企业内部晋升激励对创新绩效的影响。实证研究表明,内部高管晋升激励抑制了企业创新项目投入和产出,员工晋升激励则促进了企业创新水平提升;在企业研发投入保持不变的情况下,高管激励仍会抑制企业创新产出,员工激励则会显著正向促进企业创新绩效提升;进一步研究发现,晋升激励对企业创新绩效的影响因企业成长性水平不同存在较大差异。研究重新认识了晋升激励这一心理契约对于创新绩效的影响,对企业采取科学的激励机制具有重要的理论和实践意义。
