我国对外直接投资与出口、经济增长之间的协整分析

根据协整理论,利用中国1982~2005年的年度经济数据,对我国的对外直接投资(outward FDI)、出口与经济增长之间的关系进行了实证分析和检验。结果表明:我国的出口、GDP和OFDI之间存在着一种显著性的长期的、均衡的关系,出口对我国的OFDI有着显著的促进作用,而我国现阶段的经济增长还不足以支持我国进行大规模的对外直接投资。     

A resource-based view of green supply management

Companies are being increasingly pressured to consider environmental concerns in their manufacturing activities and, more recently, with regard to their supply bases. Despite the broad range of literature that links performance to both green manufacturing capabilities such as pollution prevention and green supply management (GSM), managers are having difficulties developing a greener supply chain. The objective of this paper is to provide a model for development of GSM capabilities. Using the resource-based view of the firm (RBV) as the theoretical background, we postulate that plant resources are positively related to green manufacturing capabilities, which in turn are positively related to GSM capabilities. The data from a survey of a sample of manufacturing plants indicates that a managerial philosophy that includes external knowledge exchange directly supports both greener process management and environmental collaboration with suppliers. However, this managerial philosophy is only indirectly related to supplier selection and monitoring. The managerial implications of these findings are twofold: managers seeking to implement GSM need to view internal investment in green process management as a step toward environmental management of their external supply chains. They also must realize that green process management requires the support of other resources, such as environmental investments and top management commitment.

The heterogeneous green vehicle routing and scheduling problem with time-varying traffic congestion

The green vehicle routing and scheduling problem (GVRSP) aims to minimize green-house gas emissions in logistics systems through better planning of deliveries/pickups made by a fleet of vehicles. We define a new mixed integer liner programming (MIP) model which considers heterogeneous vehicles, time-varying traffic congestion, customer/vehicle time window constraints, the impact of vehicle loads on emissions, and vehicle capacity/range constraints in the GVRSP. The proposed model allows vehicles to stop on arcs, which is shown to reduce emissions up to additional 8% on simulated data. A hybrid algorithm of MIP and iterated neighborhood search is proposed to solve the problem.     

The Electric Traveling Salesman Problem with Time Windows

To minimize greenhouse gas emissions, the logistic field has seen an increasing usage of electric vehicles. The resulting distribution planning problems present new computational challenges.We address a problem, called Electric Traveling Salesman Problem with Time Windows. We propose a mixed integer linear formulation that can solve 20-customer instances in short computing times and a Three-Phase Heuristic algorithm based on General Variable Neighborhood Search and Dynamic Programming.Computational results show that the heuristic algorithm can find the optimal solution in most small-size instances within a tenth of a second and achieves goods solutions in instances with up to 200 customers.     

A framework for evaluating and designing collaborative planning

Collaborative planning processes have been criticized for inefficiency, but attempts to improve them in planning of urban nature have been limited by lack of usable evaluation methodologies. This paper presents a framework for evaluating and designing collaborative processes in strategic planning of land use and nature areas. A framework with four key perspectives and their success criteria was developed with the help of literature and data from interviews and focus groups in two case areas in the Helsinki metropolitan area, Finland. Planning organizations can use the framework as a tool and source of inspiration in designing collaborative processes and their evaluation, and in shifting their practices towards the organizations’ own specified goals. A conscious design of more efficient and holistic collaborative planning can be achieved with case-specific operationalizing of this framework.     

Green supplier development: What’s in it for you,the buyer?

Greening suppliers, or cultivating environmental responsibility throughout the supply chain, has become an important strategic issue for firms. While various approaches exist, green supplier development—that is, helping and collaborating with your suppliers to reduce their negative environmental impact—is a key method that can produce significant gains for both parties at multiple levels. Yet the benefits have not been sufficiently discussed and may therefore appear nebulous for managers. Focusing particularly on “What’s in it for you, the buyer?” this article describes benefits at the intrafirm, interfirm, and market levels. Barriers to the realization of the benefits are also discussed, providing managerial guidance on supplier prioritization for green supplier development.     

Product specific values and personal values together better explains green purchase

Consumers not only buy green products to fulfil their environmental values but also seek product specific benefits from their green purchase. However, research predicting green purchases based on value-attitude integrated theoretical framework significantly overlooks an integrated approach of both personal values and product-specific values in determining green purchase intention. Employing a two-study (qualitative followed by quantitative) mixed method approach, current research fills this gap. Employing phenomenology, in-depth interviews in study-1 identified pre-dominant personal and product-specific values affecting green purchase. Employing theory of planned behaviour (TPB) and stimulus-organism-research (SOR) framework, study-2 proposed a model combining these identified values and empirically validated the model by collecting 401 online survey responses analysed through PLS-SEM. The findings from this study demonstrate that consumers green purchase attitudes and subsequent intentions are predominantly influenced by two personal values: altruism and biosphere; and two product-specific values: product quality and uniqueness. These results provide insights to organizations to craft their green marketing strategies by combining both personal and product specific values. This study extends the green consumption literature within an extended TPB plus SOR ambit.
