Reverse logistics in the Chinese auto-parts firms: implementation framework development through multiple case studies

In recent years, the implementation of reverse logistics (RL) in automobile manufacturing has drawn extensive interest from the Chinese government that has launched relevant take-back and environmental regulations and pilot projects. This study focuses on RL implementation issues in Chinese auto-parts manufacturing sector. Based on comprehensive literature review and multiple case studies in the Chinese auto-parts firms, this paper proposes a conceptual RL framework and highlights the major implementation issues. The purpose of this paper is to draw an overall picture of RL in the Chinese context, highlighting implementation issues in the auto-parts sector. Our study suggests that Chinese RL implementation requires close government monitoring mechanism and incentives, top management commitment within firms, technology and human capabilities support.

双积分政策下异质汽车制造商的产量博弈均衡

文章通过对双积分政策下汽车制造商的产量博弈均衡进行建模分析,研究了双积分政策对企业层面异质制造商的产量决策和利润的影响,以及对产业层面新能源汽车和燃油汽车总产量及总产值的影响。研究结果表明:(1)新能源汽车产业向均衡演进过程中,新能源汽车制造商仍具有一定的发展潜力,但未来发展的中坚力量依靠优势燃油汽车制造商,劣势燃油汽车制造商可能会通过提高燃油经济性发展为优势燃油汽车制造商,从而提高优势燃油汽车制造商的燃油汽车总产量,降低劣势燃油汽车制造商的燃油汽车总产量。(2)双积分政策参数对异质制造商产量决策和利润的影响不同:新能源汽车制造商能够从中受益,而劣势燃油汽车制造商面临危机,转危为安的可能方式包括降低平均燃料消耗量和积极探索新能源汽车生产的可能性。对于优势燃油汽车制造商来说,双积分政策的收紧可能导致其转向燃油汽车市场,规制NEV积分价格上限有利于引导优势燃油汽车制造商转向新能源汽车市场。(3)促进新能源汽车规模增长的参数,可能导致总产值下降,政策调整应将规模增长和产值增长作为双目标,避免单一目标可能导致的市场波动。(4)随着双积分政策的收紧,可预见的新能源汽车积分比例要求提高以及平均燃料消耗量标准趋严,将刺激新能源汽车积分需求提升,缓解新能源汽车积分供需失衡问题。考虑到目前NEV积分价格处于低位,合理降低新能源乘用车车型积分有助于限制NEV积分供给。     

An evaluation of occupational accidents in the wooden furniture industry - A regional study in South East Asia

Studies on the rate of occupational accidents among workers in the wooden furniture industry is sparse, although the industry is deemed to be highly accident prone. Therefore, the rate of occupational accidents among workers in the wooden furniture industry in Malaysia, Thailand, Indonesia and Vietnam were studied, in 240 furniture manufacturing factories, using a structured questionnaire. The findings of the study suggest that contract workers are less prone to occupational accidents compared to their permanent counterparts, and hence, are more productive. Further, the results also revealed that the contract workers have a more positive attitude towards the work, and hence, pick up the essentials of safe working practices quickly. It must therefore be recognized that the “production oriented mentality” prevalent in the wooden furniture industry, which has been argued to compromise occupational safety and health standards in the industry may be debatable. In this context, it is essential for the policy makers to re-examine the employment of contract workers for the furniture manufacturing industry, as changing the psycho-economic parameters of the industry may be warranted before the industry is deemed attractive to a permanent workforce.     

室内家具轰燃的实验研究

室内一旦发生火灾 ,轰燃出现之快慢是人们在有限的逃生时间和有限逃生能力下能否安全逃脱灾难的关键因素。笔者对室内典型家具的轰燃现象进行了实验研究 ,利用实验方法成功地观测到室内家具轰燃的全过程。介绍了轰燃实验的设计方法、实验的测量方法。大量的建筑室内家具轰燃实验 ,仍很难给出室内家具材质的轰燃准则和判别条件 ,对此应进一步开展研究工作。

家具制造企业密集区空气中VOCs污染状况及健康风险评价

采用Tenax管吸附-热脱附-气相色谱法测定家具制造企业密集区空气中挥发性有机物(VOCs),并应用美国国家环保局(USEPA)的健康风险评价模型评估其对周边人群的影响。结果表明,家具制造企业密集区总VOCs的质量浓度为0.931 mg/m3,11种目标物中乙酸乙酯、丙酮和乙酸丁酯所占比例较高,分别占总VOCs的20.2%、10.7%和9.1%。该区总VOCs的累积非致癌风险指数为3.47×10-7,低于1,不会对人体产生明显的非致癌健康危害;其累积致癌风险指数为2.49×10-5,是可接受致癌风险值(1.0×10-6)的25倍,可能对人群存在致癌影响。
