城市公共设施供给中的融资创新——一种基于政府付费或补贴的资产证券化方式

城市政府当期财政难以满足未来城市建设中的公共设施需求,城市发展需要公共融资创新."私人生产、政府付费或补贴、公众消费"模式是城市公共设施融资中一种吸引私人投资的较好模式.在该模式基础上,提出了一种基于政府付费或补贴的资产证券化创新方式,阐述了该方式的运用范围、基本结构和运作流程,并分析了该方式在城市建设中运用的基本条件.

Sectoral Energy- and Labour-Productivity Convergence

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.      

Climate Change Taxes and Energy Efficiency in Japan

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.     

中国绿色能源高质量发展水平测度研究

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。     

中国能源安全现状及其可持续发展

作为世界上第三大能源消费进口国,中国的能源安全问题和能源安全战略的实施是我国保持持续平稳发展所必须认真面对的重要课题和基本任务。本文从能源安全的基本内涵、发展历程、不同类型国家的能源安全战略对比分析以及中国能源安全现实的剖析,以发展的眼光分别在战略上和战术上提出了几大对策,从而使中国能源安全实现可持续发展。     

用能量方法求解一次超静定杆系问题

根据功能原理建立能量补充方程,并利用静力平衡方程,求解一次拉压超静定问题。该方法同时可用于扭转、弯曲等一次超静定问题的求解。     

中国能源战略评价

全球化和加入WTO，有助于中国从更大范围内解决中国的能源问题，从中国能源战略评价的角度来讲，中国能源安全问题的关键是实施石油安全战略。能源工业作为竞争性行业，必将融入到开放型经济体系中，市场化是中国能源工业发展的必然选择，中国未来能源政策的走向是国际化，利用国际，国内两个市场和两种资源，调整能源结构，协调全球和本国发展与能源及环境之间的关系，恰当地处理多种社会集团和人群利益主体与能源资源，生态环境之间错综复杂的关系，使之在良性循环的轨道上运行和发展。
