改善福建投资软环境的对策思考

近年来,福建外商投资的增长幅度有下降的态势,而且省内的许多内资企业也迁往外省。这一问题的出现,与福建省的投资环境尤其是软环境有相当程度的关系。因此,有必要对福建省的投资软环境进行分析,以便采取有效的应对措施。     

对中国“知识失业”成因的一个解释

许多国家的经验表明,在教育快速发展的过程中往往伴随着“知识失业”。近年来,我国在经历教育快速发展的同时,也开始面临这样的问题。本文以扩展的工作搜寻模型为框架,分析了当前“知识失业”产生的原因。根据分析结果,现阶段出现的“知识失业”,在很大程度上是由劳动力市场的制度性分割引起的,因此应该逐步消除劳动力市场的制度性分割,鼓励大学毕业生到西部和农村等次要劳动力市场上就业,在确定高等教育的发展规模时要适当考虑劳动力市场的发育状况。     

R/S分析与中国股市的分形特征

应用R／S分析法对中国股票市场实进行实证研究,探究中国股市的自相似性和长程相关性等分形特征;通过计算深圳成指、上证综指及各行业指数每日收益序列所对应Hurst指数及相关统计量,证实中国股市存在分形特征。但沪深两市平均循环周期存在着明显的差异。同时,各行业指数间也存在着明显的差异。     

Technological position in alliances network

The purpose of this research was to examine the interactions between the focal firm (FF) and its technological alliance, and to enquire into the technological alliance network in shaping the firm position from innovative dynamics environment. 2-Mode network analysis was employed to explore the question of how technological position emerged from alliance interaction. Specifically, we looked at the network structure of the sample by examining the interactions of technological alliance. Our empirical data were from the ‘Strategic Alliance Database’ established by the Ministry of Science and Technology in Taiwan. We identified technological position of firms from the 2-mode network analysis to resolve the highlighted question. Some results that we found were as follows: (1) The alliance network of IT technology approximated an ideal core/periphery structure. (2) The network structure apparently demonstrated that FF with a higher centrality has better opportunity to locate in the central position of FFs or in the core position in the technological network. (3) Alliance in core with a dense structure can better facilitate the utilisation of existing knowledge in refinement and extension of existing technologies. Alliance in the periphery with a non-dense structure is in a favourable position for matchmaking of experimentation and to serve as a bridge to introduce novel technologies.     

社会资本控制链架构及其稳定性研究——基于博元投资与国美电器的案例分析

在公司治理中,实际控制人同时运用股权控制和社会资本控制已是不争的事实,随着对社会资本控制链研究的深入,"社会资本契合度"替代效应"等相关概念逐渐被提出.本文在承续前人研究的基础上,将博元投资与国美电器的社会资本控制链架构进行对比分析,指出在垂直式社会资本控制链架构中,社会资本即使在股权控制水平低于相对控股时,依然具有替代效应.同时水平式的社会资本控制链易产生多个社会资本节点,致使其稳定性下降,而垂直型的社会资本控制链,因其单极和多层的架构使得整条社会资本控制链的稳定性得以提升.     

大连市发展港口物流问题研究

为顺应国家振兴东北计划,加快推进大连建设东北亚国际航运中心的步伐,我们应该突破原有港口作为单一交通枢纽基础设施的观念,结合现代物流的功能要求,大力发展大连的港口物流业。包括正确选择物流发展模式,对港口资源进行重新整合,使港口功能适应未来国际集装箱多式联运和国际物流网络节点的要求等,把大连建设成现代物流中心,以全面提升港口及城市竞争力。     

Transformation of China's energy sector: trends and challenges

The conclusions presented here sum up the contributions in the Special Issue regarding the managing of China's energy sector, particularly regarding the demand and profile of energy as well as the marketization of the sector. Strategic, organizational and policy issues relevant to the main theme are set out. Both demand and supply scenarios for the nation's energy are seen as in flux, as the economy slackens and dependence on imports rises. Unprecedented levels of urban environmental pollution and steady growth of energy consumption in the wake of a rising living standard have brought the issue to headline-prominence as never before. China's rapidly increasing renewable energy will not change its heavy reliance on coal and a lesser extent oil in the coming decade. After decades of transformation, China's energy sector now operates in a domestic market characterized by strong governmental influence and monopolistic state firms. Abroad, China's firms are exposed to heavier market pressure and competition. While the state's policies have succeeded in ensuring energy supplies and propelling China's renewable energy manufacturers into global prominence and opening up domestic market, much room for improvement exists in the competitiveness of the domestic market and domestic energy firms, transparency of pricing and the effectiveness of regulation.
