Despite starting as one of the poorest countries in the mid-1980s, Vietnam has achieved rapid developmental progress, reaching lower middle-income status in 2010. In line with rapid economic growth, Vietnam has achieved impressive progress towards the Sustainable Development Goals (SDGs) during this time. This paper sheds light on some elements of Vietnam’s success story, highlighting crucial policies in education and electricity sectors. It undertakes a forward-looking costing exercise that focusses on five sectors – education, health, roads, water, and electricity infrastructure. Achieving the remaining SDGs in Vietnam will be a challenge, with total annual additional spending needs in the 5 subsectors estimated at 7 percent of GDP by 2030.
尽管在20世纪80年代中期开始时是最贫穷的国家之一,但越南取得了快速的发展进步,于2010年达到中等偏下收入水平。随着经济的快速增长,越南在实现可持续发展目标方面取得了令人瞩目的进展。本文揭示了越南成功故事的一些要素,重点介绍了教育和电力部门的关键政策。它进行了一项前瞻性的成本计算工作,重点关注五个部门——教育、卫生、道路、水和电力基础设施。实现越南剩余的可持续发展目标将是一项挑战,到2030年,五个子行业的年度额外支出需求总额预计将占GDP的7%。

The automotive industry is a major employment generator in many economies, with millions of people earning their livelihood, both directly and indirectly. According to the International Organization of Motor Vehicle Manufacturers (IOMVM), the current turnover of the automobile industry is around 2 trillion EURO and is equivalent to the size of 6th largest economy in the world. While there has been a growth momentum for the global automotive industry in the past, it is also facing challenges of late, especially in view of the increasing cost of production and slowing down of demand. The world automotive industry is also faced with the challenge of undertaking R&D and designing fuel-efficient vehicles in view of volatile oil prices. The environmental challenges have also assumed critical importance to the automotive industry at the backdrop of climatic change.
在许多经济体中,汽车行业是一个主要的就业来源,数百万人直接或间接地谋生。根据国际汽车制造商组织(IOMVM)的数据,目前汽车行业的营业额约为2万亿欧元,相当于世界第六大经济体的规模。虽然全球汽车行业过去有增长的势头,但最近也面临挑战,特别是在生产成本上升和需求放缓的情况下。鉴于石油价格的波动,世界汽车工业也面临着进行研发和设计节能汽车的挑战。在气候变化的背景下,环境挑战对汽车工业也具有至关重要的意义。

Stringent emission and heavy tax on duty vehicle draw attention of automobile researchers to develop engine with high fuel efficiency and low emission of NOx, CO and unburnt hydrocarbon. The engine concept which combines the benefits of both SI and CI engines is termed as HCCI engine. In the current study, three dimensional model of an engine having inlet and exhaust manifold with valve profile was used for visualizing and analyzing the HCCI combustion strategy using ANSYS 16.2. Engine combustion performance parameters like combustion temperature, pressure, heat release rate and turbulent kinetic energy at different crank angles were considered for evaluation of HCCI mode. Performance was analyzed at various engine speeds (2000–3000 rpm) with same swirl number. Simulation results show that increment in wall adjacent temperature and mass average static pressure is achieved at higher engine speed in HCCI mode due to homogeneity of air–fuel mixture, however exergy destruction rate was noticed at all engine speeds.
严格的排放标准和重型汽车的重税促使汽车研究人员关注开发高燃油效率、低NOx、CO和低未燃烃排放的发动机。结合了SI和CI发动机优点的发动机概念被称为HCCI发动机。本研究采用带气门廓的进排气歧管发动机的三维模型,利用ANSYS 16.2对HCCI燃烧策略进行可视化分析。发动机燃烧性能参数,如燃烧温度、压力、热释放率和不同曲柄角下的湍流动能,被用来评价HCCI模式。在不同转速下(2000-3000转/分),以相同的涡流数进行性能分析。仿真结果表明,在高转速下,由于空气-燃料混合气的均匀性,壁面温度和质量平均静压均有所增加,但在所有转速下均存在火能破坏率。

Chevy Volt: Pricing and Capacity Decisions in Response to Government Incentives for the Electric Vehicle Industry 雪佛兰Volt:政府对电动汽车产业激励的定价和产能决策

At the end of 2013, executives from General Motors (GM) must make decisions about what production capacity and price to allocate to the Chevrolet Volt electric vehicle considering the costs of supply chain shift necessary to make changes in the assembly process. Concerns about battery life, price, and driving range have influenced most consumers' decisions to continue to purchase conventional fuel vehicles despite the U.S. federal government's implementation of incentives. What must the senior GM team do to balance concerns of cost with the potential social effect of selling a public-interest good such as the Chevy Volt? Excerpt UVA-OM-1519 Rev. Jan. 7, 2015 CHEVY VOLT: PRICING AND CAPACITY DECISIONS IN RESPONSE TO GOVERNMENT INCENTIVES FOR THE ELECTRIC VEHICLE INDUSTRY At the General Motors (GM) headquarters in Detroit, the executive team reviewed the disappointing Chevrolet Volt sales from 2013. Although sales had been rising each year since the launch in December 2010, GM was still not meeting its internal sales targets. GM had accelerated production of the Volt, believing that sales would increase as the government continued to incentivize the purchase of electric vehicles (EVs). Those incentives supported President Barack Obama’s stated goal that the United States would become the first country in the world to have 1 million EVs on the road by 2015. The executives were hoping that many of those million vehicles would be GM vehicles. Consumers, on the other end, were hesitant to invest in expensive new technology such as EVs. Despite the incentives in place, sales of EVs—the Volt included—were not even near the 1 million mark. Taking into account consumer trends, government incentives, and GM’s internal cost structure, the executives wondered if they should reconsider their decisions for the upcoming year of 2014: How much capacity should GM allocate to the Volt, and how should the Volt be priced? Electric Vehicles as Public-Interest Goods . . .
2013年底,通用汽车(General Motors)的高管们必须考虑到改变组装流程所必需的供应链转移成本,就雪佛兰Volt电动汽车的产能和价格分配做出决策。尽管美国联邦政府实施了激励措施,但对电池寿命、价格和行驶里程的担忧影响了大多数消费者继续购买传统燃油汽车的决定。通用汽车的高层团队必须做些什么,才能在成本担忧与出售雪佛兰Volt等公共利益产品的潜在社会影响之间取得平衡?在通用汽车(GM)位于底特律的总部,高管团队回顾了2013年雪佛兰VOLT令人失望的销量。尽管自2010年12月推出以来,销量每年都在上升,但通用汽车仍未能实现其内部销售目标。通用汽车认为,随着政府继续鼓励购买电动汽车,Volt的销量将会增加,因此加快了Volt的生产。这些激励措施支持了奥巴马总统的既定目标,即到2015年,美国将成为世界上第一个拥有100万辆电动汽车的国家。高管们希望这一百万辆车中有许多是通用汽车。另一方面,消费者对投资电动汽车等昂贵的新技术犹豫不决。尽管有这些激励措施,但电动汽车(包括Volt)的销量甚至还没有接近100万辆大关。考虑到消费者趋势、政府激励措施和通用汽车的内部成本结构,高管们想知道他们是否应该重新考虑即将到来的2014年的决策:通用汽车应该为Volt分配多少产能,Volt应该如何定价?电动汽车作为公共利益产品……

Sustainability is the Answer - Now What Was the Question? 可持续发展是答案——现在的问题是什么?
Pub Date : 2012-10-29 DOI: 10.2139/SSRN.2168255

Explanations for our inability to control the destructive impacts of human activities tend to focus a narrative of power — too many powerful actors are making too much money from business as usual and thus use their power to prevent change. Under this framing, law might be an agent for change — a way to blunt raw economic power through democratic mechanisms. And, indeed, this equalizing role of law is often celebrated as a tool for advancing sustainability. But, law’s ability to limit or shape the array of possible private choices is a double-edged sword. It just as readily limits our ability to imagine alternatives to the choices currently being made. While law and legal systems can, in theory, play the role of change agent, law can also cloak the status quo in a sense of inevitability. Most law, including environmental law, rests on an economic pre-commitment to dividing the natural world into discrete, ownable ‘resources’ available for exploitation. Law’s presumed neutrality, and its a priori nature are mustered to support this pre-commitment as though it were a universally-accepted, quasi-scientific truth about the purpose of legal systems. Yet, that characterization of our world is in fact a fraught, highly-contested value choice. By obscuring this starting point, law can be used to paint the existing array of choices as the only possible choices. Sustainability must therefore tailor itself to what already exists. The purpose of law dwindles to promoting a smoothly functioning market, rather than promoting justice or ensuring sustainability. It is then a small step to concluding that things have to be more or less the way they are. But, we can reclaim law’s transformative power. Law can aspire to much more than merely oiling the proverbial machine. Law creates the structure, the frame, within which private activity takes place, while at the same time law is shaped by those private activities. This reflexive nature means that law as an institution is uniquely situated to both shape and respond to the challenges of sustainability.
对于我们无法控制人类活动的破坏性影响的解释,往往集中在权力的叙述上——太多有权势的人像往常一样从商业中赚了太多的钱,因此利用他们的权力来阻止变革。在这种框架下,法律可能是变革的代理人——一种通过民主机制削弱原始经济力量的方式。事实上,法律的这种平衡作用经常被誉为促进可持续发展的工具。但是,法律限制或塑造一系列可能的私人选择的能力是一把双刃剑。它也很容易限制我们想象当前选择的替代方案的能力。虽然法律和法律体系在理论上可以扮演变革推动者的角色,但法律也可以在一种必然性的意义上掩盖现状。大多数法律,包括环境法,都是建立在将自然世界划分为可开采的离散的、可拥有的“资源”的经济预先承诺的基础上的。法律假定的中立性和它的先验性质都被用来支持这种预先承诺,就好像它是一种普遍接受的、关于法律体系目的的准科学真理一样。然而,这种对我们世界的描述实际上是一种令人担忧的、高度争议的价值选择。通过模糊这个起点,法律可以用来把现有的一系列选择描绘成唯一可能的选择。因此,可持续性必须适应现有的情况。法律的目的减少到促进市场平稳运作,而不是促进正义或确保可持续性。这是得出结论的一小步,即事情必须或多或少地保持现状。但是,我们可以重拾法律的变革力量。法律所能追求的远不止是给众所周知的机器上油。法律创造了私人活动发生的结构和框架,同时法律又被这些私人活动所塑造。这种反身性意味着,法律作为一种制度,在塑造和应对可持续性挑战方面具有独特的地位。
