针对低碳减排背景下,混合双寡头市场中企业与政府的最优决策问题,构建私有企业与部分私有化的公有企业古诺竞争博弈模型、伯特兰德竞争博弈模型以及合作模型。比较3种模型下两企业的最优减排量与产量决策,政府的最优碳税率与减排补贴率决策,两企业目标利润,社会福利与环境污染,并探讨公有企业的私有化水平对最优减排、碳税率、减排补贴率的影响。研究表明:在合作时,两企业有更大的减排力度;在竞争时,公有企业加深私有化水平会促使行业整体提高减排水平;无论是在企业竞争还是合作情形,随着公有企业私有化水平的提高,政府减排措施应该由以碳税为主转变为以碳减排补贴为主。  相似文献

Supply-chain-based organisations are nowadays facing intense pressure to abide to environmental regulatory requirements while they are striving to be responsive to customers’ needs at the least cost possible. As supply chain activities are among the top contributors to carbon emissions, several recent research works have investigated the impact of carbon regulation policies on economic and environmental supply chain performance. This paper presents integrated economic and environmental models for the one-vendor one-buyer supply chain problem under a vendor managed consignment inventory (VMCI) arrangement. Through the developed models, we study the impacts of two carbon reduction policies, namely carbon cap and carbon tax policies, on supply chain wide costs and carbon emissions. We first provide a much simpler and more compact formulation for the basic single-vendor single-buyer supply chain under VMCI agreement. We also present an environmental-based VMCI model where reduction of carbon footprint is considered as the only objective function. We then extend these two basic models to include each of the two carbon emissions reduction policies. We identify structural properties for the optimal solutions of the two hybrid economic and environmental models and propose algorithms to generate optimal solutions. The results of the computational experiments reveal that the implementation of carbon reduction policies, through carbon cap and carbon tax, may call for the adjustment of the vendor’s production and buyer’s delivery quantities to reduce carbon footprint without significantly increasing the operational costs.  相似文献

In this presentation, we discuss the heightened role of spatial informatics on both ‘sides’ of the Kyoto process, i.e. in direct emission reduction in intelligent transport, and in indirect processes and the feedback of interventions, as in land use and forest management. The development of intelligent infrastructure has an acute role in the reduction of direct emission. The embedding of infocommunication technologies increases the effectiveness of the systems, and this results in significant energy savings. Intelligent transport based on geospatial information systems is among the most important intelligent infrastructures. This article analyses the role of spatial informatics in the reduction of the environmentally damaging effects of transport. Furthermore, various indirect processes contribute to emission reduction. One is monitoring the actual environmental impact of applied emission reduction solutions, e.g. in the area of land use and forest management. Therefore, spatial informatics has a key role in the factual determination of actual environmental conditions, in the preparation of human interventions directed towards the improvement of these, in decision-making and in the impact analysis of these interventions. The article analyses the possibilities of the use of geospatial tools in monitoring the factual effects of afforestation in the framework of carbon dioxide trade related to the Kyoto process.  相似文献

在考虑碳减排技术投入下,为了实现不同碳排放政策下的供应链协调,通过建立集中式和分散式决策下的供应链模型,根据供应链协调的条件,给出了供应链实现协调的契约形式及契约参数。为了确定不同碳排放政策下的最优订货量和最优碳减排率,通过对博弈模型进行优化,提出了具体的求解方法。数值计算结果表明:随着碳排放政策的变化,供应链的最优订货量、最优碳减排率和供应链的利润也将发生相应的变化,而生产成本、缺货损失、产品残值、销售价格、批发价格等参数变化不仅会影响最优订货量、最优碳减排率和供应链利润,还会影响收益共享比例、碳减排技术投入和碳排放成本的分摊比例。  相似文献

在低碳供应链背景下,建立制造商存在资金和碳排放双重约束下的Stackelberg博弈定价模型。探究了无资金约束、提前支付和银行贷款3种情形下企业定价和制造商融资决策问题,并分析了相关因素对最优决策和利润的影响。研究表明,当银行利率小于提前支付折扣因子时,制造商始终选择提前支付融资模式;反之,制造商的融资模式选择会受到碳排放影响因子和碳价的影响。而消费者偏好绿色产品时,可以减少制造商的融资规模,但会造成制造商和零售商利润的减少。  相似文献

本文研究资金约束下制造/再制造企业考虑碳配额质押融资的生产减排决策问题,构建了资金约束时不融资和进行碳配额质押融资两种利润模型,通过算例分析自有资金及减排效用参数对产量、碳排放量和总利润的影响。研究结果表明,进行碳配额质押融资能提高产量增加利润,但也可能导致碳排放总量的增加;企业减排能力与减排效用积累量正相关,资金不足时不融资减排效用积累值较小,选择融资可以为企业未来生产减排实现共赢奠定基础。  相似文献

研究了碳标签制度下供应商参与碳减排的供应链决策问题。在考虑消费者低碳偏好情况下,探讨了3种减排模式:制造商和供应商均不投资碳减排(N模型)、仅制造商投资碳减排(M模型)、制造商和供应商均投资碳减排(SM模型)。结果表明,供应商参与碳减排投资后双方利润均多于仅制造商投资碳减排的模型,同时双方的碳排放量又少于仅制造商投资碳减排的模型,显然供应商参与碳减排促进了供应链整体经济效益和环境效益的提升。  相似文献

The world’s leading countries have reached a consensus concerning the need for environmental protection, and many international environmental protection rules and regulations have been implemented. Of these, the EU-legislated Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS), Waste Electrical and Electronic Equipment (WEEE), and Eco-design of Energy-using Products (EuP) compel the electronics industry to incorporate waste disposal considerations in product design and manufacturing in order to benefit the environment. This study accordingly employed the ISO 14000 environmental management family’s ISO 14031 environmental performance evaluation (EPE) standards as an assessment framework, and investigated the types of factors influencing environmental performance, and their level of importance, when the electronics industry implements lead-free manufacturing. The study conducted a questionnaire survey of industry experts, scholars, and government officers in Taiwan and Japan—which constitute two of the world’s leading electronics product manufacturing centers—employing the Delphi method to extract assessment indicators, and using the Analytic Hierarchy Process (AHP) method to analyze indicators’ relative levels of importance. The results showed that the choice of lead-free substitute materials, soil heavy metal pollution, and compliance with environmental laws and regulations are the three important indicators of the environmental performance of lead-free manufacturing. As a consequence, when relevant industries adopt lead-free manufacturing in the future, they should first establish basic process technology, and also take their industries’ process characteristics and the suitability of substitute materials into consideration. In order to maintain compliance with laws and regulations, and to reduce pollution emissions, such industries should cooperate with government in connection with waste and wastewater treatment. In addition, apart from implementing environmental policies and testing standards, government can facilitate the realization of environmental protection policies and help conserve corporate resources by providing assistance, specialized training, and incentive measures to industry.  相似文献

Carbon emission reduction is the only way to alleviate environmental problems, such as global warming. Effective evaluation of carbon performance can help enterprises to carry out energy saving and emission reduction activities to a certain extent and promote sustainable development. This paper constructs a carbon performance evaluation index system that includes the four dimensions of carbon resource (energy) input, cycle, output, and carbon management by incorporating the principles of circular economy and the theory of resource value circulation from the perspective of the flow trajectory of carbon-containing resources in the circulation of enterprises combined with the production characteristics of thermoelectric enterprises. Subsequently, combined with the case study, this paper discusses the scientific and practical nature of the system and provides another way of thinking for carbon performance evaluation of micro-enterprises in other industries. This paper expands the application boundary of matter–element model and supplements the literature of carbon performance, which has certain theoretical and practical significance.  相似文献

Corporate venture capital (CVC) investment in technology-intensive entrepreneurial ventures has attracted increasing attention from established firms which recognize it as a useful learning investment strategy to create diversified technological options for future change. However, there is a lack of empirical research which examines the relationship between CVC investment and the corporate investors' technological diversification. In this study, we investigate the effects of CVC investments on corporate investors' technological diversity by using 20 years of panel data from corporate investors in five high-tech industries. As a result, we find that the total amount of CVC investments and the industrial diversity of portfolio companies exhibit curvilinear (inverted U-shape) relationships with the corporate investors' technological diversity. Moreover, the empirical results show that the absorptive capacity of corporate investors positively moderates the effects of CVC investments on the technological diversity.  相似文献

This paper focuses on the impact of consumers’ preference to low carbon in the emission-concerned supply chain. In an emission-concerned supply chain, the consumers are assumed to prefer to low-carbon products. In an emission sensitive market, emission reduction not only brings the higher production costs but also stimulates the inverse demand function. Therefore, this may be an opportunity for players of the supply chain to coordinate their two objectives: environmental pressure (to reduce carbon emissions for environment protection) and profit-seeking, which intuitively seem to be contradictory. In order to address this research focus, a novel emission-sensitive demand function is adopted, and an emission -sensitive cost function is introduced explicitly to capture the deviation production cost caused by emission reduction. Then the decision-making of each member in the emission-concerned supply chain is investigated. We find that the decision-maker of the supply chain will choose different emission reduction strategies for different cases. An inspiring result shows that the channel profit as well as the emission reduction increase in the consumers’ preference to low-carbon consumption simultaneously in particular cases. Moreover, several emission-concerned contracts are designed to coordinate the channel. Another finding is that the manufacturer’s optimal carbon emissions per unit product keeps the same as the centralised channel, no matter whether the supply chain is coordinated or not. Furthermore, the further discussion reveals that less eco-friendly production than the traditional, if lack of external regulation as well as internal moral self-discipline, might be chosen under some specific conditions.  相似文献

在碳限额交易政策及消费者低碳偏好条件下,针对两个制造商(一个碳减排、一个不进行碳减排)和一个零售商组成的二级供应链,分析了碳限额及消费者碳排放敏感系数对产品零售价和最优碳减排量的影响,并利用Shapley值法协调供应链。研究发现:最优碳减排量、产品零售价不仅依赖于碳限额和消费者碳排放敏感系数,还与初始碳排放量相关;清洁型制造商最优碳排放量为零;政府应该实行差异化碳限额交易政策,对于中间型及轻污染型制造商应该适当降低碳限额,对于重污染型制造商应该适当提高碳限额并给予企业碳减排补贴;对于清洁型及中间型制造商,政府应该提供低碳消费补贴;另外政府还应该加强节能环保宣传。  相似文献
