考虑政府补贴的绿色供应链契约分析及优化研究

以政府、供应商和制造商组成的绿色供应链为研究对象,探讨政府补贴和供应链契约对绿色供应链绩效的影响。构建了批发价格契约、收益共享契约和数量折扣契约模型,比较分析了不同契约下各主体效益及契约选择偏好,设计了收益共享且绿色投入成本共担契约来提高供应链绩效。研究发现:消费者绿色偏好越强烈,产品绿色度和供应链各主体效益越高;当产品绿色度相等时,制造商更倾向于选择批发价格契约,而供应商和政府更倾向于选择收益共享契约或数量折扣契约;相较于其他契约,设计的收益共享且绿色投入成本共担契约可以提高产品绿色度和企业效益。本文为考虑政府补贴的绿色供应链企业决策及选择合理的合作契约提供了理论支持。     

Influence of freight transport purchasing processes on logistical variables related to CO2 emissions: a case study in Sweden

Emissions from freight transport stem from logistical variables such as vehicle utilisation, fuel efficiency, and distance. The purpose is to determine how shippers’ freight transport purchasing processes influence logistical variables. A multiple case study of freight transport purchasing processes was conducted, based on interviews with transport purchasers and providers. Three causes of influence of shippers’ purchasing processes on logistical variables were found: specific requirements, network structure of transport providers, and scope of contract. Specifications by purchasers, especially time requirements, influence several logistical variables (‘mode used’, ‘length of haul’, ‘load factor’, ‘empty running’, and ‘fuel efficiency’). This paper clarifies the implications of transport purchasing on CO₂ emissions in terms of logistical variables, which are understood in transportation research and practice. It describes the effects of shippers’ requirements on transport providers’ execution of transport. The results provide a foundation for shippers to discuss their influence on logistical variables with transport providers.     

Consumers and green electricity: profiling potential purchasers

Globally, consumers are beginning to be able to choose their electricity supplier. Increasing concerns about the environment are prompting some of them to consider ‘green’ electricity—that is, electricity that has been generated by more environmentally sustainable means (for example, solar power or wind power). This article profiles the potential purchaser of green electricity. Drawing upon the literature on green product purchasers more generally, three sets of hypotheses are presented—more specifically, it is proposed that those who would pay increasingly higher premiums for green electricity are more likely to possess particular demographic characteristics, attitudinal characteristics and socialization characteristics. Responses from a survey distributed in a major Canadian metropolitan area are then examined. Attitudinal characteristics—specifically ecological concern, liberalism and altruism—best identify the potential purchasers of green electricity. Suggestions for managers and marketers are made following these findings. Directions for future research are also presented. Copyright © 2003 John Wiley & Sons, Ltd. and ERP Environment.     

PURCHASING AND ENVIRONMENTAL MANAGEMENT: INTERACTIONS,POLICIES AND OPPORTUNITIES

The mechanisms are examined by which environmentally informed business practices and technologies may diffuse through industry as a result of the ‘greening’ of purchasing and supply. The efforts of official bodies in the UK to raise environmental awareness among industrial purchasers are reviewed. It is then argued that the supply chain model is an important way of interpreting the industrial landscape from a green perspective and that it is in some ways a more hopeful and positive starting point for achieving industrial transformation. The results of an analysis of some UK companies practices in using their purchasing policies to ‘green’ their supply chains are presented and opportunities for further research indicated.     

Levelling the playing field for EU biomass usage

The threats of climate change, food security, resource depletion and energy security are driving society towards a sustainable low-carbon future. Within this paradigm, biomass plays an invaluable role in meeting the food, feed, energy and material needs of future generations. Current EU thinking advocates biomass for high-value materials, which is not aligned with EU public policy support for ‘lower value’ bioenergy applications. ‘High-technology’ and ‘no bioenergy mandate’ pathways explore market conditions that generate a more equitable distribution between competing biomass conversion technologies and competing biomass and fossil technologies. In achieving greater equity, these pathways ease biomass market tensions; enhance EU food security; improve EU biobased trade balances; accelerate biomaterial sectors’ output performance and favour macroeconomic growth. Moreover, an additional 80% increase in the oil price signals a tipping point in favour of first generation biofuels, whilst simultaneously boosting output in advanced material conversion technologies even more than the high-technology pathway.     

经济适用房不同补贴方式的效果

通过数学模型,分析政府对经济适用房生产商或购买者实施补贴对购买者的效用影响、对生产商行为的影响、对政府补贴成本的影响,及至对经济适用房成交量、成交价格和净社会福利的影响。研究结果表明：对经济适用房生产商采用降低土地价格的补贴方式不如对其按单位价格补贴或按成交价的一定比例补贴,这后两种方式都更有效率,能够降低政府补贴成本,减少政府腐败行为,促进房地产商开发适合低收入者所需要的住房并提高销售效率。     

Lease finance in industrial markets

Financial leasing is being used increasingly to acquire items of industrial equipment where use is more crucial than ownership. Its advantages over traditional forms of finance are straightforward and to a large degree appear to be based on the utilization of a cost advantage deriving from the fiscal system. In view of this, it might be expected that price would be a dominant marketing variable since the ‘product’ is relatively homogeneous, even though the industry structure is oligopolistic. This has been the case to a certain extent but policies of product differentiation and market segmentation have enabled firms to avoid some of the rigours of price competition.     

Green marketing as an environmental practice: The impact on green satisfaction and green loyalty in a business-to-business context

Many companies have developed a green marketing strategy, aimed at promoting and selling green environmental products. While the majority of articles on this topic report on studies in a business-to-consumer setting, this research focusses on the impact of green marketing strategies on the satisfaction and loyalty of professional buyers in a business-to-business setting. Hypotheses were tested with survey data from 148 Dutch professional purchasers in the cleaning industry. The results emphasize the impact and importance of product quality, product price and corporate image. The most notable and strong impact on satisfaction and loyalty was found for the salesperson expertise.     

The UK and the Eurozone: Sovereign Debt Management and Monetary Policy

Events in the wake of the ‘credit crunch’ can be understood only against institutional structures within which interdependent monetary and fiscal policy are administered. In the Eurozone, the attempt to keep a central monetary authority (together with its associated national central banks) independent from 17 diverse fiscal authorities was flawed. When sovereign debt approaches unmanageable levels, the Maastricht Treaty presents austerity as the single option. In the UK, the electorate has an opportunity to choose between monetary financing (inflation) and fiscal consolidation (austerity). Policy choices within the Eurozone and the UK are set against Keynes's focus on unemployment and more recent concerns to retain (or restore) price and/or financial stability.     

Creating whole life value proxemics in construction projects

Whole life value is introduced as a concept for evaluating construction projects, which extends beyond the more typical use of optimized (equilibrium) utility preferences. By linking value and sustainability the concept allows for the consideration of ‘price‐less’ evaluations within the construction project process. As an industry exposed perhaps more than any other to issues of public space and environmental impact, construction is being driven towards the use of complex, multi‐issue consultations with stakeholders within which whole life value can operate as a contextual limit. By investigating traditional cost–benefit analysis routes, and then what are called ‘aspects of sustainability’, an argument is advanced for these consultations to be ongoing rather than one‐off events. As such, they are to concern themselves with the framework of relationships (proxemics) by which distinct evaluations might be articulated and understood through the project process, rather than just how one arrives at a consensus of opinion. It is argued that the concept of value can only be applied fully to any project if consideration has been given to the ambience and context of stakeholder relations and attitudes as opposed to just the prevailing opinions. The virtue of such stakeholder involvement lies not in its ‘rubber stamping’ a separate process of activity, but in ensuring value is realized across asset life through a focus on attaining and sustaining conditions for the reflective articulation of need.

The Negative Effects of Inappropriate Price Stimulation; The Case of Senegal: Rice Price Increases to Encourage Production May Harm Families of Non-responsive Subsistence Farmers

Abstract . Some governments of developing economieshzve been encouraged to use pricing policy to stimulate increases in food production. It is not known whether all subsistence farmers in those countries operate in an economic, financial and technological environment in which they can respond positively to price increases. In this paper models were used to demonstrate two situations: one in which farmers responded to price stimulation and another where price increases were ineffective, costly and produced results inconsistent with national goals. Data from the Basse Casamance Region in Senegal were used to show that farmers were not responsive to price changes and were net purchasers of grains. The study concludes that unless farmers' supply curves were shifted to the right—that is, that they meet more of their own subsistence needs—recent Senegalese government rice price increases could be harmful to the farm family.     

Towards commercial and environmental excellence: A green portfolio matrix

This article examines the strategic framework and options available for product strategy towards commercial and environmental excellence. It defines the environmental dimension as a ‘moving target’, explores a conceptual framework to integrate commercial and environmental dimensions and elaborates a ‘green portfolio matrix’. The proposed matrix is also empirically investigated as to its practical validity by using a set of secondary data including twelve product cases. Using the matrix, a company can diagnose its existing product mix from an environmental point of view, and furthermore can establish future ‘targets’ for an environmentally-friendly product portfolio. In addition, the matrix can be used as a framework for comparative analyses between strategic business units or for longitudinal assessment of a specific business entity.     

The Determinants of Price Adjustments in Retail Supermarkets

This paper examines the determinants of price adjustment decisions by supermarkets to increase or decrease prices for 11 different food categories and evaluates the characteristics of these firms that influence these decisions. We use a unique dataset to analyze firm variables and industry variables and their impact on price adjustment in supermarket stores. The study contributes to the price adjustment literature by identifying determinants of price behavior by stores and product category. We find that the rationale for increasing prices differs from that for decreasing prices, retailers make different adjustment decisions based on product category, and market‐level controls have little impact.

Sustainable Purchasing in Food Retailing: Interorganizational Relationship Management to Green Product Supply

Stakeholders’ demands for product sustainability redefine the focus of corporate purchasing strategies from the traditional concern with financial performance to considerations of ‘triple bottom line’ viability. This adds to the complexity of managing interorganizational relationships and poses a question regarding corporate ability to effectively leverage suppliers over environmental and social performance of supplied goods. Since it is not clear what type of purchasing relationship is more favorable for greening a product supply, the current paper aims to investigate how food retailers manage their relationships with suppliers in order to influence the environmental and social performance of procured goods and improve the availability of sustainably produced supply. The research is based on two case studies of Swedish supermarkets and supplementary semi‐structured interviews with Swedish, British and Danish supermarkets. The results of the study contribute to the existing body of academic knowledge in the field of sustainable supply chain management by developing a typology of sustainable purchasing relationships with detailed insights into the nature of collaborative practices, structure of incentives, sustainability ambition, and approaches to verification of compliance. The study has also revealed the dependence of sustainable purchasing relationships on the characteristics of the procurement context, namely the presence of well‐established sustainability certification schemes, perceived by purchaser's situation with availability of sustainability certified supply and purchaser's interpretation of the state of power dependence in relationships with suppliers.

基于政府补贴分析的新能源战略博弈模型研究

企业在新能源战略中如果不发展新能源战略带来的成本节约率ε1越高,其边际成本C1越低,新能源产品和传统产品的价格差异越大。随着消费者对每个环境满意度愿意支付的K值的增加,两个厂商的产品价格都会增加,也就是说,随着消费者环保意识的增加,环境满意度支付意愿也会增加,这样的结果不仅仅是生产新能源的厂商2受益,厂商1也会受益;政府提高市场最低绿色程度准入标准,低绿色程度的传统产品和新能源产品的价格都会增加。政府设定的市场最低绿色准入标准会对两个厂商的市场份额有影响。     

Efficient Consumer Altruism and Fair Trade Products

Consumers have shown a willingness to pay a premium for products labeled as “FT” and a preference for retailers that are seen to be more generous to their suppliers/employees. A FT product is essentially a bundle of a base product and a donation to the supplier (e.g., a coffee farmer). An altruistic rational consumer will only choose this bundle if doing so is less expensive than buying the base product and making a direct donation. For FT to be sustainable either in a competitive equilibrium or in a monopolistic environment this bundling must yield an efficiency. This efficiency is generated in the following context. A supplier’s investment reduces the retailer’s cost or boosts the final product’s quality, but this investment is not immediately observable and cannot be enforced, hence there exists a moral hazard problem. In this environment, the altruism of the consumer can facilitate a more efficient contract: by paying the supplier more the retailer can both extract more consumer surplus and increase the level of contracted investment, while preserving the supplier’s incentive compatibility constraint. We assess our model in the context of the coffee industry.     

The greening of the EC agrochemical market: Regulation and competition

This paper analyses the process of harmonisation of national pesticides regulations in the EC. One of the outcomes of this process was, in 1991, the adoption of an EC regulation which includes new environmental requirements for pesticides to be sold on the EC market. This regulatory process shows an example of trade-off between competition policy and environmental policy. After having described the competition in the agrochemical sector, the paper examines this trade-off in two ways. Firstly, the behaviour of industrial interest groups throughout the process and their influence in the devising of the regulation is considered. Secondly, the impact of competitive issues on the implementation of part of the 1991 regulation (i.e. the re-registration of old pesticides commercialised in the EC) is analysed. This case study confirms some general results of the regulatory capture theory but it also points out some limits of these theories: firms seemed to be much more sensitive to negative pay-offs than to positive ones when deciding to become involved in this regulatory process. A second insight brought up by this case study concerns the link between competition policy and environmental policy and its influence on the efficiency of the latter. Environment-competition trade-off in the agrochemical sector confronts the regulator, when it adopts environmental policy, with two risks: a risk of changing the structure of the industry (from a differentiated and innovative one to a commodity one) if the regulator does not provide sufficient pay-offs for environmental R&D costs, or a risk of allowing part of the industry to increase monopoly rents. Both risks would affect environmental efficiency, either by reducing the innovation in the sector or by over-protecting ‘greener’ pesticides from competition on price.     

Paternalism,Nudging and Liberty

The recent popularity of ‘nudge’ – involving governments structuring choices to lead individuals to choose outcomes which policymakers wish to encourage – has given rise to a belief that ‘libertarian paternalism’ offers a modern substitute for classical liberalism. But most governments are more paternalistic and less libertarian than nudge theorists. If ‘nudge’ was taken seriously, many existing laws would be repealed and few new laws would be made.     

Ethical consumers in search of markets

Research in ethical consumerism has concentrated on attempts to either categorize ethical consumers or to uncover their decision‐making processes, but to‐date there have been few investigations into the key ethical drivers behind the decision‐making process. This study attempts to identify these ethical drivers within their particular product groups by means of a survey of self‐proclaimed ethical consumers distributed via a questionnaire placed in the Ethical Consumer Magazine. The findings indicate that environmental issues are ranked above human rights and animal rights/welfare issues and that the ethical consumer considers the product groups to have differential importance ranging from the food products goods group, being the most strongly associated with ethical issues, to the ‘brown goods’ group (electric goods such as stereos and TVs), which proved to be least associated with these issues. An examination of the ethical drivers within each group suggests that ethical consumers consider each product group on the basis of its bundle of ethical attributes, with differing levels of importance placed on each ethical issue within the purchase decision.

Environmental regulation and innovation driving ecological design in the UK automotive industry

The theory of ecological modernization asserts that economic and environmental goals can be integrated within a framework of industrial modernity. Its central tenet is that environmental regulation can stimulate the application of ‘clean’ technologies or techniques. Ecological modernization also contends that environmental regulation can offer business benefits from innovation through improved product design and economic performance. The EU End of Life Vehicles Directive (ELVD) reflects many of these principles, as it compels all car manufacturers to ‘take back’ and dismantle vehicles at the end of their useful lives and to remove the hazardous substances from the production process. Each component will then be either reused or recycled. The legislation forces designers to introduce ‘clean design’ and ‘design for disassembly’ practices. In light of this, we examine the impact of the directive on UK automotive component manufacturers. We find limited evidence that the EU ELVD Directive has driven product innovation beyond short‐term, incremental technological trajectories. We therefore conclude that a more radical approach, in line with the ‘dematerialization’ thesis by Dobers and Wolff (1999), is needed to generate more radical, ecological design solutions within the UK automotive industry.
