消费升级背景下大数据能力对商业模式创新的影响机理——基于小米和网易严选的案例研究

在消费升级背景下,数据正呈爆炸式增长,给企业带来了机遇与挑战,新的商业模式不断涌现。本文基于动态能力和大数据理论,以小米和网易严选为例,研究了在消费升级背景下大数据能力对商业模式创新的影响机理和路径问题,发现大数据能力通过客户价值、企业资源和能力、盈利模式驱动商业模式创新的三条路径。探讨了资源整合能力、深度分析能力和实时洞察与预测能力三个维度之间的关系,并构建出大数据能力对商业模式创新的影响机理模型,可以拓展大数据能力和现有企业商业模式创新的相关内容。     

浙江省中小企业对区域经济的贡献度研究

中小企业作为区域经济发展不可忽视的重要力量,已经越来越受到人们的重视。依据2003-2008年浙江省统计年鉴数据,基于GRD经济贡献度测算模型,对浙江省中小企业对区域经济的贡献度进行定量计算和分析,结果表明：浙江省中小企业的工业产值在总产值中占到了绝对的比重,连续五年保持在80％以上;自2004--2008年,浙江省中小企业对浙江工业经济总产值的年均贡献率为81．61％,说明了中小企业对浙江省的区域经济贡献度之大是目前省内的大型企业所无法比拟的,显示出中小企业的发展对浙江省经济发展具有较强的主导性。     

综合性社会契约视角下的社会责任投资决策

社会责任投资起源于20世纪60年代西方社会,它是企业社会责任的一种实践活动。目前在欧美等发达国家,社会责任投资已逐渐成为一种主流基金投资模式,并为越来越多的投资者所认可,而在我国,对社会责任投资尚处于了解阶段。综合性社会契约理论是美国学者多纳得森和邓菲于1994年提出的一个将企业社会责任和社会伦理相衔接的重要理论。文章介绍和评析这两个理论并尝试建立基于综合性社会契约理论的社会责任投资模型,希望借此对投资者进行社会责任投资决策产生一定的理论指导。     

Macroeconomic effects of structural reforms and fiscal consolidations: Trade-offs and complementarities

This paper studies the impact of product and labour market structural reforms and the effects of their joint implementation with alternative debt consolidation strategies. The set-up is a dynamic general equilibrium model calibrated for the Greek economy. The results show that structural reforms produce important long-run GDP gains that materialize earlier, the faster the reforms are implemented. When implemented jointly with fiscal consolidations, structural reforms may amplify the short-run costs of fiscal tightening. The GDP dynamics depend on the fiscal instrument used for public debt consolidation. In the long run, however, there are complementarity gains irrespective of the fiscal instrument used.

基于PSR模型的广东省城市土地集约利用空间差异分析

将＂压力—状态—响应＂框架引入到城市土地集约利用评价指标体系中,采用主成分分析方法对评价指标进行赋权,对广东省21个地级市的城市土地集约利用水平进行了评价。结果表明,广东省城市土地利用集约度差异形成的主要影响因素是地理区位条件和经济发展水平,资源赋存状况也是重要的制约条件。城市土地集约利用是一个复杂的系统工程,不仅要注重提高土地利用的产出效益,还要重视系统压力状态的调节和系统反馈能力建设。研究也表明,PSR评价指标体系及主成分分析方法能较好地适应城市土地集约利用评价的需要。     

贵州省产业园区基础设施融资模式研究

产业园区最早出现于19世纪末西方工业化国家中,并在第二次世界大战后得到了迅速的发展。产业园区创造的工业总产值对GDP的贡献作用意义非凡。对于经济欠发达的贵州而言,产业园区的建设对于促进贵州经济的良好发展起着举足轻重的作用。对贵州省产业园区基础设施融资模式进行研究,提出贵州省产业园区基础设施融资模式具体的融资方案设计,以此为产业园区基础设施顺利建设,进而为产业园区健康、持续与长远的发展,进一步地促进贵州省经济又好又快发展奠定坚实的基础。     

Do global CO2 emissions from fossil-fuel consumption exhibit long memory? a fractional-integration analysis

In this article we use an autoregressive fractionally integrated moving average approach to measure the degree of fractional integration of aggregate world CO₂ emissions and its five components – coal, oil, gas, cement, and gas flaring. We find that all variables are stationary and mean reverting, but exhibit long-term memory. Our results suggest that both coal and oil combustion emissions have the weakest degree of long-range dependence, while emissions from gas and gas flaring have the strongest. With evidence of long memory, we conclude that transitory policy shocks are likely to have long-lasting effects, but not permanent effects. Accordingly, permanent effects on CO₂ emissions require a more permanent policy stance. In this context, if one were to rely only on testing for stationarity and non-stationarity, one would likely conclude in favour of non-stationarity, and therefore that even transitory policy shocks have permanent effects. Our fractional-integration analysis highlights that this is not the case.     

Incorporating innovation subsidies in the CDM framework: empirical evidence from Belgium

ABSTRACT

This paper integrates innovation input and output effects of R&D subsidies into a modified Crépon–Duguet–Mairesse (CDM) model. Our results largely confirm insights of the input additionality literature, i.e. public subsidies complement private R&D investment. In addition, results point to positive output effects of both purely privately funded and subsidy-induced R&D. Furthermore, we do not find evidence of a premium or discount of subsidy-induced R&D in terms of its marginal contribution on new product sales when compared to purely privately financed R&D.
