Closed-loop supply chain network equilibrium strategy model with environmental protection objectives

With the increasing popularity of ecological civilization and sustainable development,enterprises should consider environmental protection measures in their operations in addition to pursue their economic interests.This paper establsihes a closed-loop supply chain network model composed of multiple suppliers,manufacturers,retailers,recyclers,and demand markets—regarding their dual goals of the profit maximization and the minimization of carbon emissions.The conditions necessary for establishing overall equilibrium and an equilibrium model of the entire closed-loop supply chain network are determined by applying variational inequality and dual theory.A modified projection contraction algorithm is used to design a model-solving program.Finally,using numerical examples,the paper conducts a comparative static analysis on important parameters such as the weight coefficients of environmental protection objectives and consumers'awareness of low-carbon environmental protection and attains some beneficial enlightenment on management.The results indicate that when the environmental protection objectives of a certain type of enterprise increases,both the economic benefits and environmental protection performance will improve;when the environmental protection objectives of all enterprises increases simultaneously,environmental protection performance improves significantly,but the changes in economic benefits of different enterprises are inconsistent and profit coordination is more complex.Although consumers’awareness of low-carbon preference could improve environmental performance,it reduces the overall profits of network members and the entire closed-loop supply chain network as a whole.The above conclusions can be used as a reference for the government in designing low-carbon environmental protection policy and in closed-loop supply chain research.

New Direction of Fashion Design——The Fashion Designing of Green Circulation Consumerism

Green circulation consumerism is the mainstream consumer attitudes in the 21st century,originally derived from green consumption.The costume designing of green circulation consumerism is also known as eco-clothing,green clothing.The designs should meet the health,safety andcomfort requirements;meanwhile it should fulfill sustainable development,resource conservation and other various requirements.

论环境法发展观的价值维度——面向消费主义的批判与超越

对消费主义的迷醉构成了现代性发展理念的灵魂。由消费主义所制导的发展观,在逻辑与现实中必然造成人与自然的对峙,并进而导致严重的社会异化和生态环境的危机。环境法走出了消费主义的狭隘伦理观,将和谐理念贯穿于整个法律规范之中,它是站在和谐的角度上反对消费主义。环境法坚持和主导的发展观是协调共生的和谐发展理念,是一种能够体现人与自然、人与社会、人与自我三重价值维度的和谐发展理念。

识别及其治理:消费主义视角下的生态环境风险

消费主义作为一种意识形态和生活方式,深度冲击着人和自然的和谐关系,引发了人为原因导致的生态环境风险。资本逻辑的制度根源、异化劳动的实践根源和工具理性的认识根源共同构成消费主义视野下生态环境风险生成的内在逻辑。消费主义导致的生态环境风险具有渐进性、累积性和隐蔽性等特征,呈现出环境安全风险、环境健康风险、环境国际风险以及环境伦理风险等不同风险样态。为此,应牢固树立生态环境风险意识,完善社会主义条件下资本运行的驾驭和导控机制,持续推动绿色消费方式的构建,努力提升生态环境风险的治理能力。

自然中心主义环境伦理思想产生的缘由探究

自然中心主义环境伦理思想作为目前最为热门的学科之一,自然同其它学科一样,有它产生的思想根源、现实缘由和直接的动因。工业社会的精神失落和蓬勃兴起的绿色运动是其思想诱因与直接动因,而它形成的现实缘由则主要是全球面临的生态困境以及对人与自然关系的重新认识。

媒介物质性:机器的道德经济

构成数字通信环境的机器,其基础设施和组件建立在一系列资源的基础上,这些资源通过生产、维护和处置的链条转化为人工制品/人造物(artefact)。然而,这些日常使用的背景条件仍是大部分主流传播研究的盲点。本文探讨了为什么会有这样的研究盲点,并认为数字技术在高级资本主义组织机构中越来越显著的中心性,加上物联网和人工智能的迅速扩张,将媒介的物质性推向分析的中心,并提出了关于其环境及社会成本的重要伦理问题,并呼唤新的机器道德经济学的发展。
