太阳能光伏发电在我国经历了快速的推广应用,虽因享受高额财政补贴而备受争议,但太阳能光伏发电逐步摆脱对财政补贴的依赖,已经达到了平价上网的条件。本文回顾了我国光伏发电上网电价下降的历程,探讨了促进上网电价逐步下降的驱动力。建立以内部收益率(IRR)为平价上网光伏发电项目经济性评价的模型,分析了影响平价上网太阳能光伏发电项目经济性评价的“弃光”严重、非技术成本高企、补贴拖欠等因素,通过算例分析计算了其影响程度,并对解决这些障碍因素从政府和企业两方面提出了对策与建议。 相似文献

We examine the pricing difference of Green Bonds (GB) and conventional bonds (CBs) in capital markets worldwide. Credit spread is used to observe whether investors would like to pay a premium for GBs over CBs. This study uses panel data regression with hybrid model to analyse daily observations over the period 2016 to 2017. We employ Option-Adjusted spread (OAS) to measure the credit spreads of bonds while controlling for bond specific, macroeconomic and global factors that influence the spread. With the hybrid model used in the panel data analysis, we were able to capture the fixed-effects of variables in a random effect model. We find that GBs are traded at a premium of 63 basis points (BPS), compared with a comparable corporate bond issue. We find that the green label provides issuers an incentive to raise funds through issuing GBs while providing investors an opportunity to diversify their investments returns. Our findings provide several implications to the major stakeholders driving the GB market to scale up the market to finance the required level of global green investment needs. We stress an urgent need to support the growth of the GB market to achieve sustainable development through mitigating climate change challenges.Abbreviation GB: Green Bond; CB: Conventional Bond; YS: Yield Spread; BPS: Basis Points; OAS: Option-Adjusted Spread; PCSE: Panels Corrected Standard Errors; CPI: Consumer Price Index; GBPs: Green Bond Principles; CBS: Climate Bond Standard 相似文献

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy
cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops
(switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops,
annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural
usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program
lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually
by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually
yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor
the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram
lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually
by US $2.8 billion above baseline. 相似文献

20世纪90年代以来,全球金融体系从严格的分业经营逐渐走向混业经营,由金融机构间跨行业、跨国界收购与合并而形成的金融机构集团化经营逐步成为一种趋势。中国金融业也只有顺应国际金融业发展的潮流,加大金融改革的力度,实现国内外金融市场的接轨,打造世界一流的金融控股公司,才能在国际金融的激烈竞争中立于不败。 相似文献

This paper investigates hybrid inflation‐price‐level targeting (HT), employing a Phillips curve with output persistence. By HT we mean that a central bank targets a weighted average of the optimal inflation rate and its corresponding price level. The analysis shows that if output is persistent to some extent, it is desirable to adopt HT because, relative to the case of alternative regimes such as inflation targeting (IT) and price‐level targeting (PT), it will reduce the variability of inflation and thereby social loss. In addition, it is shown that the optimal hybrid‐type target is uniquely determined according to the degree of persistence in output. 相似文献

基于复杂供应链库存管理策略的系统动力学研究 总被引:4,自引:0,他引:4
在分析了具有不同提前期和加工时间的复杂供应链特点基础上,研究了混合CONWIP/Kanban库存管理思想与同步CONWIP库存管理思想在复杂供应链上的应用。同时借助Vensim建模平台。针对这两种管理思想建立了基于复杂供应链系统的动态仿真模型,并对模拟结果进行了分析。 相似文献
