我国制造业合作研发知识溢出的实证研究

利用空间自相关Moran指数与集群分析的空间计量经济学空间误差模型和空间滞后模型,结合Griliches&Jaffe知识生产函数(Knowledge Production Function,KPF),对我国省域制造业合作研发进行空间计量经济分析。分析结果发现:我国31个省域制造业企业新产品创新能力的贡献主要由企业研发投入实现,合作研发对制造业新产品创新能力没有明显的知识溢出作用。如何建立有效的合作研发机制和相互作用机制是目前我国制造业面临的一个关键问题。

Fractional Integration Versus Structural Change: Testing the Convergence of $$\hbox {CO}_{2}$$ Emissions

This paper assesses the stochastic convergence of relative \(\hbox {CO}_{2}\) emissions within 28 OECD countries over the period 1950–2013. Using the local Whittle estimator and some of its variants we assess whether relative per capita \(\hbox {CO}_{2}\) emissions are long memory processes which, although highly persistent, may revert to their mean/trend in the long run thereby indicating evidence of stochastic convergence. Furthermore, we test whether (possibly) slow convergence or the complete lack of it may be the result of structural changes to the deterministics of each of the relative per-capita emissions series by means of the tests of Berkes et al. (Ann Stat 1140–1165, 2006) and Mayoral (Oxford Bull Econ Stat 74(2):278–305, 2012). Our results show relatively weak support for stochastic convergence of \(\hbox {CO}_2\) emissions, indicating that only between 30 and 40% of the countries converge to the OECD average in a stochastic sense. This weak evidence disappears if we enlarge the sample to include 4 out of the 5 BRICS, indicating that our results are not robust to the inclusion of countries which are experiencing rates of growth which are far larger than those of the OECD members. Our results also decisively indicate that a slow or lack of convergence is not the results of a structural break in the relative \(\hbox {CO}_{2}\) emissions series.     

中国企业股票期权行权期限问题研究

行权期限作为股票期权激励机制的基本要素之一,是影响股票期权激励机制发挥作用的关键。股票期权行权期限在中国实际应用中存在法律法规不规范,证券市场不健全,职业经理人市场不完善及公司治理结构、生命周期不成熟等问题。因此,应加大研究力度,提高调研人员素质,规范法律法规,完善公司治理结构,建立健全市场体系,以实现合理的股票期权行权期限确定机制。     

国企购并的基本原则、操作误区及矫正策略

国企购并是根据市场经济的原则对资源进行有效配置的重要手段,也是从总体上盘活国有经济的重要举措,其行为主体应该是企业,但却必须在政府的政策引导和国家的法律保障的范围内有序进行。在具体实践过程中,由于思想认识上的偏差,国企购并陷入了操作中的误区,政府自觉不自觉地充当了国企购并的主体。因此,要想进一步规范国企购并的操作,就必须尽快出台有针对性和可操作性的相关法律法规,明确政府与企业之间责、权、利的范围和边界。     

基于U-TRIZ的SAFC分析模型

汲取经典TRIZ以及现代TRIZ各分支理论的精华,构建了物质-属性-功能-因果(SAFC)分析模型,明确了统一TRIZ(U-TRIZ)的解题流程,统一并准确定义了关键术语,并结合3个实例介绍了SAFC分析模型的应用与转换步骤。结果表明:SAFC分析模型便于工程师们准确找到技术系统中产生有害功能的物质或组件的属性,并借助于"效应知识库"对那些不需要的属性实施变、增、稳、减、测的有效操作,极大地提高了TRIZ的学习和使用效率。     

海峡两岸餐饮业税收比较

中国大陆与中国台湾地区(以下简称"两岸")均对餐饮业的经营收入征收流转税、对其经营所得征收所得税、对其拥有的财产征收财产税,对其发生的某种行为征收行为税。由于两岸情况不同,所征税种也有着各自不同的特点。本文首先比较了两岸餐饮业税收的相同与不同之处,最后提出了完善大陆餐饮业税收的对策。     

Variable selection for varying coefficient models with measurement errors

This paper focuses on variable selections for varying coefficient models when some covariates are measured with errors. We present a bias-corrected variable selection procedure by combining basis function approximations with shrinkage estimations. With appropriate selection of the tuning parameters, we establish the consistency of the variable selection procedure, and derive the optimal convergence rate of the regularized estimators. A simulation study and a real data application are undertaken to assess the finite sample performance of the proposed variable selection procedure.     

How to respond to competitors' green success for improving performance: The moderating role of organizational ambidexterity

With increasing environmental competitions between companies, there is a pressing need to explore how the environmental pressures from rivals influence focal firms' actions and the subsequent performance consequences. On the basis of social contagion theory and upper echelons theory, we examine whether firms respond to competitors' green success through green supplier integration, which further improves firm performance, and the moderating effect of organizational ambidexterity. The research explores hypothesized relationships adopting hierarchical regression analysis and bootstrapping method by collecting survey data from 206 Chinese manufacturers. Our findings suggest that competitors' green success positively influences green supplier integration. Green supplier integration mediates the impacts of competitors' green success on financial and environmental performance. In addition, the combined dimension of organizational ambidexterity plays a positive moderating role in the impacts of green supplier integration on financial and environmental performance. This study expands previous literature and managers' practices on green supply chain management.
