中国城市的经济韧性及由来:产业结构多样化视角

面对诸多来自内外部环境的不利因素,中国经济的"韧性"变得尤为重要。本文开创性地将经济韧性引入对中国现实情况的实证研究中,在反事实实验的框架下运用GMM-SL-SAR-RE模型分期测度230个城市的经济韧性,同时构建涵盖工业与服务业44个大类的产业结构多样化指标和产业结构调整指标对城市经济韧性的差异性进行解释。研究结论显示,面对2008年全球金融危机的外部冲击,中国各城市间的经济韧性表现出较大的差异性,拥有多样化产业结构的大城市更能抵御风险。更为重要的是,当经济进入恢复调整期后,越多样化的城市就越具有调整能力,这些城市通过发展"新经济",激励新一轮更高效的生产活动,从而获得长久和坚实的经济韧性。由此可见,多样化的产业结构不仅有助于城市抵御外部冲击,而且能够为冲击后的适应性结构调整提供更大的空间,是中国城市经济韧性的关键所在。     

Excess value and restructurings by diversified firms

We examine whether restructuring decisions by diversified firms are related to their excess values. We find that changes in diversification level, measured as changes in the number of segments or number of industries, are positively and significantly associated with excess values. Further, at lower levels of excess values, firms are significantly more likely to increase focus than maintain their existing levels of diversification and, at higher levels of excess values, they are significantly more likely to diversify further than maintain or reduce their current levels of diversification. These findings indicate that excess value variations are meaningful and predict restructuring decisions.

经济结构调整目标下的财政货币政策协调

财政政策与货币政策在宏观调控中有不同的作用,在经济结构调整目标下两者的协调显得愈加重要。新时期中国的宏观经济面临着诸多的挑战,在此阶段财政政策和货币政策应在宏观经济调控目标指导下,在工具选择、政策时效与政策功能等方面积极协调配合,努力解决当前经济发展中的突出矛盾,优化经济结构,增强可持续发展能力。     

Telecom Market after Restructuring

What happened? A telecom-restructuring plan was announced on May 24, 2008,encouraging the fixed-line operator China Telecom to buy China Unicom's code-division multiple access (CDMA) network (both assets and subscribers).The remnants of China Unicom, mainly its GSM network,are expected to be merged with China Netcom.The fundamental telecom service of China Satcom would be merged into the business of China Telecom;and China     

Structural adjustment in the Latin American and African mobile sectors

In recent times, there has been much discussion about structural changes taking place on the mobile front in Europe and the USA but rather little on developments elsewhere. However, it is in Latin America and Africa where the structure of the mobile sector has recently been undergoing the most rapid and unprecedented change. This paper sets out to explain what has happened in each case covering the period to end-2005, to explain the underlying rationale and to seek finally to answer the question whether there is a common pattern in both cases or whether they are essentially independent.     

On the speed and boundaries of structural adjustment when fiscal policy is tight

Governments of transition economies are subject to fiscal constraints (e.g. credit constraints). However, exaggerated fiscal discipline might feed into the structural adjustment process. The government designs and times the privatisation programme, yet may find itself in a fiscal squeeze because restructuring moves costs from firms to the public budget. This paper models this problem in a simple dynamic set-up. Several distinct reform strategies, which differ in the speed and level of structural adjustment, are identified. Tight fiscal discipline in early stages of transition may delay or halt privatisation. A different sequencing of policy or different taxation, benefits, and privatisation sales rules, can rectify this problem.

Budgeting for Equality: The Australian Experience

Gender budgets have now been introduced in varying forms in more than forty countries throughout the world. These exercises emerged out of feminist practical politics initially in Australia and later in a number of other countries. The idea of gender budgets gathered further momentum when the United Nations Beijing Platform for Action called for the integration of a gender perspective into budgetary decision-making. Most of these experiments share three core goals. They seek to: (1) mainstream gender issues within government policies; (2) promote greater accountability for governments' commitment to gender equality; and (3) change budgets and policies. However, very little research has examined their success in achieving these goals. In discussing the lessons learnt from the Australian experience, this paper adopts a feminist political economy perspective on the state as an analytical starting point for discussing the future of gender budgets elsewhere in the world.
