 [PDF]


Journal of Low Carbon Economy (JLCE) , 2015, DOI: 10.12677/JLCE.2015.44006
Abstract:
当前,我国人造板产业落后产能过剩,资源浪费和环境污染严重,产业上下游企业之间缺乏有效的合作和协调机制。本文结合人造板产业实际,界定了一个枝桠材供应商和两个相互竞争的人造板制造商组成的人造板绿色供应链系统;进而,分别构建了增值税即征即退和环境税等政策引导下人造板绿色供应链的质量竞争、合作与协调模型,并建立了政策引导下人造板绿色供应链的收益分享–成本分担质量协调机制,并进行了对比数值分析。研究结果表明:(1) 有条件的增值税即征即退政策和征收环境税政策,使得人造板企业有经济动因开展人造板绿色供应链管理,提高资源能源利用率和企业竞争力;(2) 人造板绿色供应链管理模式的资源循环利用和绿色环保优势,使得人造板企业有内在动力开展绿色供应链管理改进活动,推进产业的转型和升级;(3) 协调情形下的人造板绿色供应链及其成员的最优利润均高于竞争和合作情形,收益分享–成本分担的契约协调机制具有高效协同和帕累托改进的优势;(4) 通过自建经济林场、选用经济材,强化技术研发和工艺流程改进,降低加工成本和绿色供应链管理成本,有助于提高人造板供应链整体及其成员的运营绩效。
Currently, China’s wood based panel (WBP) industry is faced with backward overcapacity, waste of resources, environmental pollution, and lack of efficient cooperation and coordination mechanism between the upstream and downstream. Considering the practice of WBP industry, WBP green supply chain system with one branch-wood supplier and two competed WBP manu-facturers is defined, further, quality competition, cooperation and coordination model of WBP green supply chain under the policy guidance of value-added tax refund and environmental tax collection are respectively built, and the quality coordination mechanism of revenue-cost sharing for WBP green supply chain under the policy guidance is built, finally, the comparative numerical analysis is carried out. The results show that: (1) the policy of value-added tax refund with threshold and environmental tax collection makes WBP enterprises have economical motivation to implement green supply chain improvement, improving the efficiency of resources and energy, reducing the pollution emissions and improving the overall performance and competitiveness; (2) owing to the advantages of resource recycling, green environmental protection and high comprehensive efficiency in the WBP green supply chain management mode, WBP enterprises have internal motivation to carry out green supply chain improvement, promoting industrial restructuring and upgrading; (3) the optimal profits of supply chain and its members under coordination situations are higher than those under competition and cooperation situations, and coordination mechanism of revenue-cost sharing contract has advantages of high efficiency, cooperation and Pareto improvement; (4) self-construction of the economic forest farm and the choice of economical branch-wood can effectively reduce the unit cost of branch-wood, enhancing technology development and process improvement can effectively reduce the processing cost and improvement cost of WBP green supply chain management, which is beneficial for improving the

Abstract:
当前,我国人造板产业落后产能过剩,资源浪费和环境污染严重,上下游企业之间缺乏有效的合作和协调机制,同时,战略顾客行为对于人造板上下游企业的协调运营决策有着重要的影响。本文结合我国人造板产业实际,界定了人造板三级绿色供应链系统;在增值税即征即退和环境税政策引导下,分别构建了战略顾客行为下的人造板三级绿色供应链收益分享–成本分担契约协调模型和传统人造板绿色供应链收益分享–成本分担契约协调模型,并进行了对比数值分析。研究结果表明:1) 有“门槛”的增值税即征即退补贴的政策以及征收环境税的政策,使得人造板企业有经济动因积极开展绿色供应链管理改进,提高资源能源利用率,提高企业综合运营绩效和竞争能力。2) 无论是传统人造板供应链视角还是人造板绿色供应链视角,收益分享–成本分担契约均可以实现战略顾客行为下人造板三级绿色供应链协调运营,且绿色供应链视角下的人造板供应链及其成员最优利润高于传统供应链视角,人造板供应链及其成员有经济动因实施绿色供应链管理改进。3) 强化地板产品促销价格的高低影响到人造板绿色供应链的优化决策和运营绩效,制定一个较低的促销价格,有利于提高人造板绿色供应链及其成员的绩效。4) 通过自建经济林场、选用经济型枝桠材等措施有效保障枝桠材供应,强化技术研发和工艺流程改进,促进资源能源回收和循环利用,有助于提高人造板绿色供应链的运营绩效。
Currently, China’s wood-based-panel (WBP) industry is faced with backward overcapacity, waste of resources, environmental pollution, with slow growth of downstream product demand and relative shortage of upstream branch-wood supply. Obviously, the development of the upstream does not match with the downstream in the WBP supply chain, and lack of efficient cooperation and coordination. Besides, strategic consumer’s behavior has an important impact on the coordination decision for the upstream and downstream of WBP enterprises. Considering the practice of WBP industry, WBP three-stage green supply chain system with one branch-wood supplier, one WBP manufacturer and one WBP processor is defined; further, under the policy guidance of value- added tax refund and environmental tax collection, the coordination models of WBP three-stage green supply chain and traditional WBP three-stage supply chain, considering the strategic consumer’s behavior, are respectively built via revenue sharing-cost allocation contract, finally, the comparative numerical analysis is carried out. The results show that: 1) The policy of value-added tax refund with threshold and environmental tax collection makes WBP enterprises have econo- mical motivation to implement green supply chain improvement, improving the efficiency of re- sources and energy, and improving the overall performance and competitiveness. 2) No matter under the perspective of traditional WBP supply chain or under the perspective of WBP green supply chain, revenue sharing-cost allocation contract can achieve coordination operations of WBP three-stage green supply chain, considering strategic consumer’s behavior; besides, the optimal profits of WBP supply chain and its members under the perspective of green supply chain are higher than that under the perspective of traditional supply chain. WBP supply chain and its members have economic incentives to implement green supply

Abstract:
当前,我国人造板产业落后产能过剩,资源浪费和环境污染严重,其下游加工产品需求增长较慢,而上游枝桠材供给相对不足,人造板供应链上下游发展不匹配,缺乏有效的沟通与协调,人造板供应链同质化竞争严重。本文结合人造板产业实际,界定了人造板制造商和人造板加工商组成的人造板绿色供应链系统,进而,在增值税即征即退和环境税政策引导下,构建了多链竞争下的人造板绿色供应链协调模型,并进行了对比数值分析。研究结果表明:(1) 有“门槛”的增值税即征即退补贴的政策以及征收环境税的政策,使得人造板企业有经济动因积极开展绿色供应链管理改进,提高资源能源利用率,提高企业综合运营绩效和竞争能力。(2) 两部制价格契约可以有效地协调多链竞争下人造板绿色供应链运作,人造板绿色供应链要避免同质化竞争,而是通过降低单位枝桠材成本、人造板产品单位加工成本和强化地板的单位加工成本,与竞争对手拉开差距,以获得异质化竞争优势,有助于提升人造板绿色供应链的运作绩效。(3) 通过自建经济林场、选用经济型枝桠材等措施有效保障枝桠材供应,强化技术研发和工艺流程改进,促进资源能源回收和循环利用,有助于提高人造板绿色供应链的运营绩效。
Currently, China’s wood-based-panel (WBP) industry is faced with backward overcapacity, waste of resources, environmental pollution, with slow growth of downstream product demand and relative shortage of upstream branch-wood supply. Obviously, the development of the upstream does not match with the downstream in the WBP supply chain, and lacks an efficient cooperation and coordination. There are serious homogeneous competitions among WBP supply chains. Considering the practice of WBP industry, WBP green supply chain system with one branch-wood supplier and one WBP manufacturer is defined; further, under the policy guidance of value-added tax refund and environmental tax collection, the coordination models of WBP green supply chain, considering the homogeneous competitions among WBP supply chains, are respectively built; finally, the comparative numerical analysis is carried out. The results show that: (i) the policy of value- added tax refund with threshold and environmental tax collection makes WBP enterprises have economical motivation to implement green supply chain improvement, improving the efficiency of resources and energy, and improving the overall performance and competitiveness. (ii) Two-part tariff contract can effectively coordinate WBP supply chain operations under homogeneous com-petitions among multi-chains. WBP green supply chain should avoid the homogeneous compe- tition, but gain a heterogeneous competitive advantage via reducing the unit cost of branch-wood, the unit processing cost of WBP products and the unit processing cost of laminate flooring, which is beneficial for improving the operational performance of WBP green supply chain. (iii) Self- construction of the economic forest farm and the choice of economical branch-wood can effectively guarantee the branch-wood supply, enhancing technology development and process im- provement can effectively promote the recovery and recycling of resource and energy, which is beneficial for improving the operational performance of

Abstract:
为了解城市河流水质组成特征及其随季节变化规律,搜集了宿州市沱河水质检测数据,对水质特征及其影响因素进行分析,结果表明:不同水化学指标均受到环境不同程度的影响,PH值雨水期最高、冬季较低,DO含量夏季较高,为二类水质,EC、DO和TN在春、秋季含量较高,NH3-N、TP在冬季含量偏高,而BOD在冬季含量较低,COD、Mn受季节影响不大。通过单因子指数评价方法对水质进行评价表明,春、秋、冬三个季节为Ⅳ类水,在夏季为Ⅴ类水,夏季水质变差主要受到温度升过、有机物排放等影响。
In order to understand the river water quality in city and their variation characters, the testing data of Tuohe river water were collected in Suzhou city; the characters and influenced factors of water quality were discussed, and the results showed: the different chemical indicators of water quality were influenced by diverse environment factors; in detail, the pH values are highest in rain and lowest in winter, while the DO is higher in summer. EC, DO and TN are all have higher value in spring and autumn, while the NH3-N, TP have higher content in winter. The content of COD and Mn are stable, with the season influencing limited. The single factor index was used to evaluate the water quality, and the results showed the river water could be subdivided as IV in spring, autumn and winter, while in summer the river water quality could be as V, what could be caused by the temperature, organic emission etc.
