This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis
is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals
that the development over time of the cross-country variation in productivity performance differs across sectors as well as
across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation
of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis
that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity.
Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific
steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively.
We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization
play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.

In 2003 Japan proposed a Climate Change Tax to reduce its CO2 emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the
revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and
Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless
the subsidy encourages improvement in energy intensity well beyond Japan’s recent historical experience. Similar demand-management
programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be
to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading.
We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that
when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive
exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount
of the Russian allowance is not available in international markets. 相似文献

在"创新、协调、绿色、开放、共享"五大发展理念中,绿色协调发展成为关系中国可持续发展全局的重要理念,而绿色能源高质量发展是绿色高质量发展中的一个重要有机组成部分。本文构建了涉及绿色能源投资、生产、消费和减排4个系统的9个细化指标,利用熵权TOPSIS法实证测度2017年中国绿色能源高质量发展水平,并深入分析各区域之间的差异。通过研究发现:中国30个省区绿色能源高质量发展的水平在4个子系统和综合水平方面的表现均存在差异,综合水平总体呈现"东中部高且比较接近,而西部中等偏低"的区域分布格局;然后依照绿色能源高质量发展综合水平的高低,把30个省区划分为领先型、中等型和落后型3种类型。进而深入把握中国绿色能源高质量发展水平的区域分布规律,为统筹推进各省区协同提升中国绿色能源高质量发展水平提供较为可靠的依据。 相似文献

我国经济增长一直居于高位,但已有几种伴生现象,主要是商品过剩、资金过剩和失业率上升,正蕴育着一些风险或危机。这三者都是由生产过剩所引起。生产过剩意味着消费相对于生产已严重滞后。因此,要根治生产过剩,化解经济风险,关键是大力促进消费增长,并以消费启动经济运行全过程。坚持以消费带动投资增长,这是消费启动所固有的内涵和基本要求。 相似文献

In this paper we propose a sequential strategy, based on the microeconomic approach of the demand theory, in order to test for separability between private and public consumption. The aim of the present work is to verify, using a conditional almost ideal demand system, whether the different components of public consumption exert conditioning effects on the allocative structure of private spending. The empirical estimation of the model and the separability tests are developed for both a demand system in five functional categories of private spending, and for a demand system in six categories, where the private expenditures on those goods and services which can also be offered by the public sector are enclosed in a single functional category. The results of the separability tests, obtained using UK data for the 1974–2000 period, show that public individual consumption plays an important role in modifying consumer choices, while public collective consumption does not affect private consumption behaviours. The relationships between the different components of private spending and public individual consumption are both of substitutability and complementarity; in particular, we find that public individual consumption and the corresponding private expenditures on ‘Health, education, recreation and social protection’ are complements. 相似文献

从政府责任的角度,提出“完全信息”假设强合理性的观点,从而恢复了新古典经济学关于“完全信息”假设合理性的本来地位。在此基础上,提出政府监管对乳品质量相对完全信息的提供以及对乳品消费拓展具有重要作用。并就政府乳品安全监管机制的选择以及政府在乳品消费习惯形成中的责任进行了探讨。 相似文献

当前中国经济社会处于快速转型期,伴随着改革进程的不确定性风险日趋凸显,成为制约居民消费进一步扩张的重要因素。本文采用2003~2017年中国省级面板数据,考察了商业保险对居民消费行为的影响效应及其作用机制。研究发现,以商业保险密度和保险强度为表征的商业保险发展对居民消费有着显著正向影响,相较于农村居民消费,商业保险对城镇居民呈现更强的消费效应,同时财产保险消费效应明显高于人身保险对居民消费影响,进一步地,中介效应检验发现,不确定性缓解可能是商业保险影响居民消费的一个重要机制。基于此,本文认为,构筑完善的商业保险服务体系对于启动居民消费具有重要意义。 相似文献
