Thermal upgrades of existing homes in Germany: The building code, subsidies, and economic efficiency

One of the cheapest ways to reduce CO₂ emissions is thermal renovation of existing homes. Germany is a world leader in this project, with a strict building code, generous state subsidies, and an advanced renovation infrastructure. The effects of its policies are here explored in the light of progressive tightening of the building code, and the strict criteria for subsidies. Data on costs and outcomes of residential building renovations are presented from published reports on renovation projects, and cross-checked with projects investigated directly. Comparisons are made in terms of euros invested for every kilowatt hour of heating energy saved over the lifetime of the renovations, for standards ranging from 150 kWh (the lowest standard) to 15 kWh (the highest) of primary energy use per square metre of floor area per year. It is found that the lowest standard is an order of magnitude more cost-effective than the highest, in terms of both energy saved per euro invested, and return on investment over the lifetime of the renovations, regardless of fuel prices. It is argued that this throws into question Germany's policy of progressively regulating for higher renovation standards, and offering subsidies only for projects that go beyond the minimum standard.

国内移动终端市场管制政策变迁的原因分析

从1987年到2007年的二十年间,中国移动终端市场管制政策的变革过程就像一个钟摆,经历了市场失灵、政府管制、管制失灵、放松管制、市场再次失灵、期待重新管制的反复轮回,但无论是管制还是放松管制,都是围绕着达到市场资源合理配置而左右摇摆。推动＂钟摆＂周而复始摆动下去的力量,来自于各方利益的博弈。     

Technological innovations and 3G mobile phone diffusion: Lessons learned from Japan

Technology and innovation become more important determinants of corporate competitiveness, and the telecommunications sector is no exception. A good example is found in the development of the mobile phones. Technological development, embodied in innovative functions developed from the first (1G) to third generation (3G) systems, has played significantly important roles in the growth and upheavals of the Japanese mobile phone market. In addition, development in contents, value-added services which are supplied by related firms formed in the vertical structure, charging systems, handset development; all these have made this small gadget an increasingly important part of daily life.
