森林作为陆地上最大的碳库,其碳汇能力俨然成为各国应对全球气候变化不利影响的主要措施,如何准确地估算森林碳汇价格对于森林碳交易市场的完善以及森林碳汇能力的发挥具有重大意义。基于中国1990—2018年林业发展的相关数据,利用超越对数生产函数模型,通过自相关检验与多重共线性检验并结合岭回归分析方法推导出森林碳汇价格的核算方程,运用此价格核算方程估算了中国1990—2018年的森林碳汇价格。研究发现:中国1990年的森林碳汇价格为8.422元,而到了2018年其价格已经上涨到387.282元,年均增长率为14.56%,年均价格为120.294元。森林碳汇价格总体上随着时间以及投入要素的变化呈现出不断上涨的趋势,但也存在一定的波动。 相似文献

黑龙江省发展森林碳汇贸易实证研究 总被引:1,自引:0,他引:1
森林生态系统在全球碳循环与平衡中具有极为重要和不可替代的作用。黑龙江省森林资源丰富,是我国最主要的林区,巨大的"碳汇"既具有重要的生态功能,也蓄藏着潜在的巨大经济利益。本文运用森林蓄积量扩展法,依据黑龙江省《关于加强林业强省建设的决定》中确立的目标,分别计算了黑龙江省2010年和2020年的森林生物量碳汇贸易潜力和森林全部碳汇贸易潜力。计算结果表明黑龙江省森林碳汇贸易潜力巨大。与此同时,本文在实证研究的基础上,为了使黑龙江省的森林碳汇贸易潜力得以更好地发挥,也提出了一些可行性建议,这些建议能否收到实效,还有待实践予以证明。 相似文献

目前,绝大多数碳汇交易成本方面的文献都以经济学成本角度出发,对碳汇交易全过程所发生的成本费用分为不同部分,大多是从宏观层面统计核算角度进行研究,而从微观层面会计核算角度特别是有关确认、计量等深层次问题的研究就更少。其实对于碳汇的购买方和销售方来说,双方碳汇交易过程中考虑的因素不同,各自成本费用也不同,碳汇交易是发达国家出钱向发展中国家购买碳排放指标,通过市场机制实现发展中国家生态价值补偿,允许经营者可以通过森林的可认证减排量和木材收入两个方面获益。中国作为发展中国家,我国林业发展正面临着资金不足的问题,合作造林项目正好提供了该资金,项目完成后,森林具有直接固碳作用,成为碳汇的销售方,通过碳汇交易带来经济补偿,当森林固碳作用消失后,木材也可带来经济收入。林业生产成本的高低直接影响林业生产的经济效益和经营者参与碳汇交易的积极程度。 相似文献

气候变暖是人类社会面临的十大生态问题之首,而人类社会大量排放二氧化碳等温室气体形成的温室效应则是气候变暖的根源。通过对我国开展森林碳汇贸易潜力的理论分析可以发现我国在发展森林碳汇贸易上具有可行性和迫切性,并通过对我国开展森林碳汇贸易潜力的实证分析发现我国开展森林碳汇贸易的潜力是巨大的。我国应当采取适当措施积极参与到国际温室气体减排,将森林碳汇贸易的潜力化为现实,促进中国林业经济的发展。 相似文献

The devastating Sichuan earth- quake is recently estimated to have indirectly caused RMB 30 billion to 60 billion in damage and the total economic losses could be as high as RMB 105 billion to 190 billion,and it will also slow the growth of the nation's economy by 0.15 to 0.2 percentage points during the second to fourth quarter of the year, according to the Southwest Securities research and development center. 相似文献

An updated supply of storage is estimated to reflect recent developments in the literature. This study adds a measure of price variability, specifically implied volatility. It also adds a measure of the call‐option value to sell stocks before the end of the storage period, specifically a measure developed by Heaney (2002). The model is estimated for U.S. soybean stocks carried between crop years. A quadratic relationship is found between stocks to use ratio and implied volatility. A statistically significant, inverse, linear relationship is found between the storage‐cost–adjusted spread and the estimated call‐option value. This finding is consistent with the much debated idea that convenience yield is a return to storage that can offset losses from storage when intertemporal price spreads are negative. © 2006 Wiley Periodicals, Inc.

Not long ago, the National Bureau of Statistics released its 2007 Macro Economy Index. Social consumption retail sales reached RMB 8.9 billion, increased by 16.8 percent over the previous year, or 3.1 percentage points higher; the whole investment in social fixed assets was valued RMB 13.7 billion, a year-on-year increase of 24.8 percent, that is 0.9 percentage points higher; and trade surplus amounted to RMB 24.7 billion, rising by 47.7 percent compared with the same period last year, 26.3 percentage points falling over the increasing speed last year. According to preliminary estimates, GDP for the year was RMB 24.67 trillion, up by 11.4 percent from the previous year, 相似文献

Mould Industry is seen as the "mother" of other industries. In recent years, this industry .in China has had a fast development. From 1996 to 2002, the production value of die and mould industry increased at a rate averaged 14% per year or so. In 2003, the production value increased by 25% from a year ago, to RMB 45.0 billion, amounting to US$5.0 billion and ranking the third in the world. According to the data from CDMIA, 相似文献

2011年我国能源消费快速增长,节能减排工作出现反弹。究其原因,一方面是因为"十一五"末期以行政手段强制完成的减排指标本身含有水分;更主要的是,从工业化、城镇化进程中的产业结构调整滞后带来能耗高居不下,基础设施建设导致"碳存量"积累,生活方式转变导致"碳通量"增加,土地用途转变使得"碳汇"转为"碳源"。因此,经济结构战略性调整势在必行,城镇化必须强调节能减排。 相似文献

While political disputes occur frequently and widely among many countries, their impact on the international trade is unclear and less systematically investigated. Considering the 2012 Diaoyu Islands Dispute, under several premised assumptions, this paper applies the international trade Inoperability Input-Output Model to determine the indirect economic loss and to screen out Chinese industries that are sensitive to the dispute. Results based on Leontief's technical coefficients matrix show that the total indirect economic loss of China's gross trade is between RMB 540.4226 billion and RMB 1023.3068 billion. Industries that are sensitive to the dispute include electrical equipment and machinery, general special equipment manufacturing, metal smelting and rolling processing, manufacture and processing of metals and metal products, and chemical. The empirical findings suggest that China establish an early-warning mechanism and trade assistance system, so that key industries that were damaged could be properly compensated. 相似文献
