港口经济与城市经济系统耦合协调度实证研究

我国正处于港口高速建设和城市迅速发展时期,协调港口和城市功能的关系对提高港口城市的综合能力具有重要意义。在深入分析港城经济系统耦合机理的基础上,采用熵权法选取港口经济与城市经济的耦合元素指标,并以深圳港为例,运用耦合度模型与耦合协调度模型进行实证分析,动态把握港口经济与城市经济的耦合协调状态。研究表明,2000~2011年期间,深圳港口经济与城市经济两大系统的耦合系统程度趋向转好,耦合发展类型由严重不协调衰退向高级协调发展转变,并有向优质协调发展的趋势,体现了两大系统的协同效应。     

Vietnam’s economy: Achievements and perspective

In last several years, Vietnams economy has reached significant achievements. Those are clearly seen by analyzing economic growth, economic structure transformation, trade and investment and Vietnams economy competitiveness. However, in the process of development, Vietnams economy is still facing many difficulties and challenges. Vietnam is accelerating speed of innovation process, is active and quicker in international economic integration in order to complete the economic – social objectives in the period of 2001–2005 with annual average economic growth rate of 7.5%.     

Countervailing institutional forces: corporate governance in Turkish family business groups

This longitudinal study investigates the impact of national and international pressures to improve corporate governance in an emerging economy from an institutional theory perspective. Recently, family business groups (FBGs), the dominant form of organizing in emerging economies, have been criticized by policy makers for their poor governance structures. A common recommendation to FBGs has been increasing the number of independent, outsider directors on their boards. Thus, change in the board compositions of the quoted subsidiaries of the six biggest FBGs is analyzed over 2002–2006. One-way-ANOVA and t-tests were used as statistical tools. Findings reveal that there has not been a statistically significant change in board compositions over the research period. FBGs were found to resist institutional pressures through ‘avoidance’, ‘defiance’ and “manipulation” strategies due to the absence of coercive pressures and multiple forms of ‘institutional work’ for change.

Understanding platform business models: A mixed methods study of marketplaces

Recent technological advances have enabled the emergence of novel business models based on digital platforms. Marketplace like Airbnb or Uber offer such digital platforms to connect previously unmatched demand-side and supply-side participants through innovative forms of value creation, delivery and capture. While countless firms claim to offer the next ‘Airbnb for X’ or ‘Uber for Y’, we lack knowledge about the defining business model characteristics of these marketplaces. To close the gap, this paper provides a conceptually and empirically grounded taxonomy of their business models. Applying a mixed methods approach, it first develops an integrative framework of marketplace business models. Guided by the framework, the research systematically analyzes 100 randomly selected marketplaces with content analysis and binary coding. The gathered data is analyzed with cluster analysis techniques to develop a taxonomy for marketplace business models. The clustering process reveals six clearly distinguishable types of marketplace business models and thus shows that there is no one-size-fits-all approach to creating, delivering, and capturing value with marketplaces and platforms in general. We characterize these distinctive types on basis of the qualitative and quantitative findings. Among others, we find that two of these types are highly aligned with business model characteristics associated with the so-called sharing economy. The findings are discussed against platform, marketplace, and sharing economy literature to contribute to a higher integration of different literature streams that are concerned with similar organizational types and phenomena.     

基于理想解和灰关联度的动态评价方法及其应用研究

为了对多个多属性（指标）待评价对象（方案）在多个时间点的发展状态和该时间段内的总体发展水平进行比较分析,根据理想解法和灰关联度法优缺点,提出基于理想解和灰关联度的动态评价方法。该方法基于三维数据,将欧氏距离和灰色关联度相结合,提出一种新贴近度,同时反映了位置关系和数据曲线的相似性差异,兼顾评价指标值差异程度和增长程度。最后将该方法应用于"十二五"期间省域循环经济生态效益评价,通过实例验证该方法实际应用上的有效性。     

二元结构、实际汇率与巴拉萨—萨缪尔森效应——基于面板门限模型的实证分析

运用Hansen提出的面板门限模型,以二元结构为门限变量,研究了43个国家1980~2010年不同收入国家,基于二元结构变化的巴拉萨—萨缪尔森效应的大小(B-S效应),研究发现:二元结构对B-S效应的影响存在明显的双门限效应,高收入国家不存在二元结构问题,其B-S效应显著;中等收入国家基本上跨过了第一门限值,其B-S效应存在,但弱于高收入国家,而低收入国家基本不存在B-S效应;表明在不同二元结构下,由于工资不会同劳动生产率同步增长,劳动生产率对实际汇率的存在不完全传导机制,可以解释"人民币汇率之谜"。     

供应链企业碳减排投资策略选择与行为演化研究

基于当下气候变暖的背景中有社会责任感的消费者对低碳产品有特殊偏好的情境,研究上游企业主导的供应链在面对具有低碳产品偏好的市场消费者时,上下游企业的减排投资行为与策略。依照Stackelberg博弈模型,构建上下游企业采用不同的行为策略的支付矩阵。进而,应用演化博弈理论中双种群演化博弈模型分析得到上下游企业减排投资行为的演化稳定策略:当需要较大的投资或者下游企业分担减排成本意愿较强时,由处于主导地位的上游企业实施投资减排是稳定的;当需要较小的减排投资或者下游企业分担减排成本意愿较弱时,上下游企业组成的供应链中必然会有一个企业实施减排。最后,指出了减排投资系数和下游企业分担投资成本比例的不同对演化博弈稳定均衡的影响。     

Sustainable supply chain management and the transition towards a circular economy: Evidence and some applications

In the last decades, green and sustainable supply chain management practices have been developed, trying to integrate environmental concerns into organisations by reducing unintended negative consequences on the environment of production and consumption processes. In parallel to this, the circular economy discourse has been propagated in the industrial ecology literature and practice. Circular economy pushes the frontiers of environmental sustainability by emphasising the idea of transforming products in such a way that there are workable relationships between ecological systems and economic growth. Therefore, circular economy is not just concerned with the reduction of the use of the environment as a sink for residuals but rather with the creation of self-sustaining production systems in which materials are used over and over again.Through two case studies from different process industries (chemical and food), this paper compares the performances of traditional and circular production systems across a range of indicators. Direct, indirect and total lifecycle emissions, waste recovered, virgin resources use, as well as carbon maps (which provide a holistic visibility of the entire supply chain) are presented. The paper asserts that an integration of circular economy principles within sustainable supply chain management can provide clear advantages from an environmental point view. Emerging supply chain management challenges and market dynamics are also highlighted and discussed.
