应对气候变化的政策手段多种多样,市场机制手段是目前应用广泛的政策工具之一。国际碳交易的实践尤其是欧盟ETS的运行效果显示,电力及一些能源加工转换行业通常会因为承担了碳交易的成本,而会导致其下游产品价格的发生变动,一般表现在下游电力价格的增加,因此会使得其他行业的生产成本受电力价格的上涨而增加。因此碳价格机制的引入对于整个经济发展的成本产生一定的影响,而我国目前以出口贸易为导向的经济现状,势必使得碳价格影响到出口贸易的产品成本上。本文主要利用我国2005年和2007年的投入产出表,测算我国出口贸易产品能源成本的变化。结果显示我国出口产品的能源成本占每年出口额比重约为13%,若扣除掉消耗进口中间产品的因素,仅仅考虑国内中间投入产品的能源成本,则出口产品中的能源成本比重下降至9%-10%左右,其中电力的成本约占整个能源成本的60%以上,若由于碳价格机制的引入导致电力成本上涨50%,则使得我国出口能源成本的至少上涨一半以上,这将大幅度降低我国出口产品的国际竞争力。因此我国出口贸易的主要部门一方面需要不断加强技术研发投入,提升其生产技术水平,降低能源成本的比重,提高单位产品的能源效率;另一方面由于我国外贸存在较大的顺差,也要不断调整出口产品的结构,配合国内产业政策的调整,降低能源成本较高产品的出口,优化出口产品的结构,提高出口产品的科技含量和附加值,整个贸易政策调整优先向竞争力导向转变。 相似文献

As drivers of terrestrial ecosystems, humans have replaced large carnivores in most areas, and human influence not only exerts striking ecological pressures on biodiversity at local scales but also has indirect effects in distant corners of the world. We suggest that the multibillion dollar cashmere industry creates economic motivations that link western fashion preferences for cashmere to land use in Central Asia. This penchant for stylish clothing, in turn, encourages herders to increase livestock production which affects persistence of over 6 endangered large mammals in these remote, arid ecosystems. We hypothesized that global trade in cashmere has strong negative effects on native large mammals of deserts and grassland where cashmere‐producing goats are raised. We used time series data, ecological snapshots of the biomass of native and domestic ungulates, and ecologically and behaviorally based fieldwork to test our hypothesis. In Mongolia increases in domestic goat production were associated with a 3‐fold increase in local profits for herders coexisting with endangered saiga (Saiga tatarica).That increasing domestic grazing pressure carries fitness consequences was inferred on the basis of an approximately 4‐fold difference in juvenile recruitment among blue sheep (Pseudois nayaur)in trans‐Himalayan India. Across 7 study areas in Mongolia, India, and China's Tibetan Plateau, native ungulate biomass is now <5% that of domestic species. Such trends suggest ecosystem degradation and decreased capacity for the persistence of native species, including at least 8 Asian endemic species: saiga, chiru (Pantholops hodgsoni), Bactrian camel (Camelus bactrianus), snow leopard(Panthera uncia), khulan(Equus hemionus), kiang (E. kiang), takhi (E. przewalski), and wild yak (Bos mutus). Our results suggest striking yet indirect and unintended actions that link trophic‐level effects to markets induced by the trade for cashmere.

Abstract: International wildlife crime is burgeoning in this climate of global trade. We contend that the most effective way to contain this illegal trade is to determine where the wildlife is being removed. This allows authorities to direct law enforcement to poaching hot spots, potentially stops trade before the wildlife is actually killed, prevents countries from denying their poaching problems at home, and thwarts trade before it enters into an increasingly complex web of international criminal activity. Forensic tools have been limited in their ability to determine product origin because the information they can provide typically begins only at the point of shipment. DNA assignment analyses can determine product origin, but its use has been limited by the inability to assign samples to locations where reference samples do not exist. We applied new DNA assignment methods that can determine the geographic origin(s) of wildlife products from anywhere within its range. We used these methods to examine the geographic origin(s) of 2 strings of seizures involving large volumes of elephant ivory, 1 string seized in Singapore and Malawi and the other in Hong Kong and Cameroon. These ivory traffickers may comprise 2 of the largest poaching rings in Africa. In both cases all ivory seized in the string had common origins, which indicates that crime syndicates are targeting specific populations for intense exploitation. This result contradicts the dominant belief that dealers are using a decentralized plan of procuring ivory stocks as they became available across Africa. Large quantities of ivory were then moved, in multiple shipments, through an intermediate country prior to shipment to Asia, as a risk-reduction strategy that distances the dealer from the poaching locale. These smuggling strategies could not have been detected by forensic information, which typically begins only at the shipping source. 相似文献

In the trade and environment debate, the relevance of examining the impact of a location's intra-industry trade (IIT) on environmental quality cannot be overemphasized, in part, due to the increasing prominence of such trade and the paucity of related empirical evidence. Although existing studies largely indicate overall trade to be pro-environment, the consequences of IIT may differ owing to greater varieties of intermediate and final goods, easier technology diffusion via trade in similar goods, productivity gains from within-sector reallocations, and increased innovation. However, identification of the causal effect is plagued by the potential endogeneity of IIT attributable to crucial unobservables and measurement error. In this light, utilizing an instrumental variables strategy and data on multiple environmental indicators from roughly 200 countries over 2000-2005, we investigate IIT's impact on the environment. To measure IIT, we rely on two indexes of within-industry specialization based on changes in and levels of sector-level trade. Regardless of the indicator of IIT or environmental performance, across several sets of instruments, we mostly find (i) IIT to benefit the environment, (ii) overall trade to be less pro-environment than IIT, and (iii) concerns over endogeneity to be relevant. 相似文献

Conservation conflicts are increasing on a global scale and instruments for reconciling competing interests are urgently needed. Multicriteria decision analysis (MCDA) is a structured, decision‐support process that can facilitate dialogue between groups with differing interests and incorporate human and environmental dimensions of conflict. MCDA is a structured and transparent method of breaking down complex problems and incorporating multiple objectives. The value of this process for addressing major challenges in conservation conflict management is that MCDA helps in setting realistic goals; entails a transparent decision‐making process; and addresses mistrust, differing world views, cross‐scale issues, patchy or contested information, and inflexible legislative tools. Overall we believe MCDA provides a valuable decision‐support tool, particularly for increasing awareness of the effects of particular values and choices for working toward negotiated compromise, although an awareness of the effect of methodological choices and the limitations of the method is vital before applying it in conflict situations.

Hudson’s Bay Company records were used to estimate the 1786–1911 annual number of moose (Alces alces andersonii) and caribou (Rangifer tarandus caribou) involved in trade by northern Ojibwa natives to the company post at Osnaburgh House (51°10′N 90°15′W) in northwest Ontario,
Canada. The human population for the early 19th century, and the number and severity of human starvations from 1786 to 1911
were estimated. The extent of forest fires in the region around Osnaburgh was documented using a “fire-day” index computed
from Hudson’s Bay Company journals and using qualitative archival information. It is argued that the human population was
too small to have caused the observed early 19th century moose and caribou population decline solely through predation. Likewise,
severe early 19th century famines were caused by climatic factors rather than by declines in moose and caribou numbers. Habitat
change caused by increased forest fires correlates with the observed decline of caribou, while moose increased and subsequently
collapsed as winter shelter was destroyed. A burgeoning human population, sustained during winter food shortages on potatoes
donated by the Hudson’s Bay Company, then kept ungulate populations to low levels until the late 19th century. Only then did
maturing forests and a new outbreak of fires provide renewed habitat for resurgences of, respectively, caribou and moose. 相似文献
