基于生态文明观的循环经济发展思路

党的十八大将生态文明建设提到前所未有的高度,提出要着力推进绿色发展、循环发展、低碳发展。循环经济是生态文明建设的重要内容,虽然经过几年的实践,我国的循环经济工作已经取得了一定的效果,但是在新时期生态文明观的指导思想下,仍然需要大力推进循环经济的发展。文章提出基于生态文明观的循环经济发展思路与建议。     

公共财政中的生态补偿模式比较研究

生态补偿机制是解决生态环境问题、实现环境资源有偿利用的重要政策工具,选择合适的生态补偿模式对于我国的生态补偿实践具有重要意义。而我国生态补偿模式过多依赖政府主导,生态补偿的市场化交易模式发展缓慢。为提升生态补偿效率,我国的生态补偿应在优化政府补偿模式的基础上,通过法律制度的完善、管理体制的健全和市场交易机制的激活来促进市场补偿模式的发展,实现生态补偿的政府主导和市场调节相结合。

Has the ‘franc fort’ exchange rate policy affected the inflationary dynamics? Theory and new evidence

Abstract

This paper examines the impact of the ‘franc fort’ policy implemented in France from 1983 on the inflationary dynamics by means of a square root Kalman filter approach. An interesting aspect of the analysis is the evidence that the ‘franc fort’ exchange rate policy had a significant impact on the inflationary dynamics in France through its credibility effects. These results confirm the imported credibility hypothesis according to which the French authorities accelerated the disinflation process by importing the German monetary policy credibility through the ‘hard peg’ of the franc–DM exchange rate. These findings show that inflation dynamics in France began to converge significantly to that in Germany after the implementation of the ‘franc fort’ policy, making more credible the plan for the final transition to the euro. Moreover, this analysis may also reveal much about the nature of potential success of the current initiative of the new member countries now in the process of joining the EU and looking eventually to adopt the euro.

Analysing enterprise architecture maturity models: a learning perspective

In order to aid organisations in the adoption of enterprise architecture (EA) best practices, maturity models have been proposed in the literature. These models offer organisational roadmaps and assessment frameworks for increasing EA maturity. However, key questions concerning the implied meaning of the term maturity in the context of these models have been left unexplored by previous research. This research, aided by the field of organisational learning, offers new insights into the implied assumptions of current EA maturity models and offers initial concepts and constructs to guide the conceptualisation, construction and refinement of enterprise maturity models.     

De Facto Exchange Rate Regime Classifications: An Evaluation

There exist several statistically-based exchange rate regime classifications that disagree with one another to a disappointing degree. To what extent is this a matter of the quality of the design of these schemes, and to what extent does it reflect the need to supplement statistics with other information (as is done in the IMF’s de facto classification)? It is shown that statistical methods are good at the basics (distinguishing some type of peg from some type of float), but less helpful in other respects, such as determining whether a float is managed, particularly for countries that are not very remote from their main trading partners. Different measures of exchange rate volatility have been used but are not primarily responsible for differences between classifications. The theoretical underpinning of particular classification schemes needs to be more explicit.     

中国城镇化与经济增长关系的理论与实证研究

国际经验表明工业化和城镇化是带动一个国家或地区经济增长的双核。中国城镇化远远落后于工业化,可以作为新时期拉动经济增长的重要战略选择。理论层面,经济增长通过收入效应 、规模效应、结构效应推动城镇化进程;城镇化则通过投资拉动机制、消费刺激机制、产业优化机制、创新激励机制促进经济增长。实证层面,选取1978～2012年城镇化率和人均GDP 的时间序列数据,通过协整检验、格兰杰因果检验、脉冲响应和方差分解等计量分析发现, 我国城镇化和经济增长之间存在稳定长期的均衡关系;选取2008～2012年省际面板数据测算全国和东、中、西部省份城镇化水平的泰尔指数,结果显示中国城镇化的省际差异总体呈现缩小趋势。
