中日一次能源消耗的碳排放及影响因素对比分析 总被引：3，自引：0，他引：3
中国和日本是一次能源消费大国,煤、石油和天然气消费比例较高,温室气体排放量较大。受国内能源强度、能源消费结构以及能源效率水平等因素的影响,日本国内碳减排成本远高于我国。《京都议定书》规定的国际碳减排机制为日本实现温室气体境外低成本减排提供了平台,也为我国带来了项目融资和引进环境技术的新机遇。但是,中日清洁发展机制环境合作的实践表明,国际碳减排机制对日本等发达国家实现碳减排目标的贡献较大,而对我国碳排放量的控制贡献较小。我国要想从根本上改善能源消费结构、实现碳减排,必须走低碳经济的发展道路。 相似文献

依据CDM项目的开发流程,将湖南在国家发改委获批、执行理事会（EB）注册和GER签发三个阶段数据与其它省市区比较后发现,湖南CDM项目开发虽然发展较快,但仍然存在开发不足、项目规模小、项目类型少等问题。立足于湖南实际,应当从加强宣传和专业人才队伍建设、完善中介服务机构、拓宽项目领域、强化政策支持等方面推进湖南CDM项目的稳健发展。 相似文献

ABSTRACTThis note starts with a retrospective view of the CDM model [Crépon, Bruno, Emmanuel Duguet, and Jacques Mairesse. 1998. “Research, Innovation and Productivity: An Econometric Analysis at the Firm Level.” Economics of Innovation and New Technology 7 (2): 115–158.] as an econometric framework for studying innovation and growth. A narrative interpretation of CDM describes the chain from innovative activity at firms to increases in welfare and makes links to the policy environment. Filling in missing pieces of the innovation to productivity puzzle has a heavy data burden. The paper makes use of the micro moments database (MMD) that allows observing micro-level behavior and macro-level impacts of innovation and production in a large selection of European countries. Two examples are given of research using the MMD. First, we estimate a simplified system of innovation and production equations that can be applied to average firm choices and outcomes, as well as to industry or aggregate outcomes. We find that innovative activity contributes to aggregate productivity even while the average effect at the firm level is insignificant. Next, a cross-country exploration is made that shows heightened productivity effects of combined use by firms of various enterprise-level information and communications technologies. 相似文献

In this article we unpack the ‘black box’ of carbon offsetting through a critical examination of the technologies and techniques that create carbon credits. Drawing on empirical research of compliance (Clean Development Mechanism) and voluntary carbon offset markets, we highlight the diversity of technologies, techniques and devices involved in carbon offsetting, ranging from refrigerant plants to systems of calculation and audit. We suggest that polarised debates for and against offsetting do not adequately reflect the considerable variations between types of offset project and governance practices in the compliance and voluntary offset markets. Using conceptual insights from governmentality theory and science and technology studies we assess the tensions in making standard, fungible carbon credits. In conclusion, we suggest attention to the technologies and materiality of carbon offsetting allows a fresh perspective on somewhat entrenched debates about the advantages and disadvantages of offsetting. 相似文献

CDM (Crépon, Duguet and Mairesse, 1988) is a workhorse model in the economics of innovation, which explains productivity in a three-stage procedure driven initially by R&D and leads to patents and then to productivity improvements. Based on the logic of this model, an increasing number of papers applies it to emerging economies but modifies the original model without being explicit about the nature and implications of this modification. We argue in this paper that, in its original form, CDM does not capture stylized facts of the determinants of productivity in emerging economies and that we need alternative models. Accordingly, we are critical of papers that try to maintain the validity of the model but actually change it. For that purpose, we test the original CDM model and its two alternatives: investment and production capability–driven models. Our research is based on a large sample of firms in Central and Eastern Europe, former Soviet republics and Turkey, and we show that the alternative models are much closer to the stylized facts of innovation activities and technology upgrading in these and other emerging economies. Our conclusions have important policy implications, which we discuss. 相似文献
