区域经济发展与城市化

城市化是社会经济发展的必然趋势,也是国家或区域的地域空间系统中的一种复杂的社会过程。改革开放以来,加速城市化进程是我国更为坚定不移的发展目标。众多区域的经济发展是推动城市化进程的主要动力。进入21世纪以来,我国城市化进程取得了重大进展,但长期以来一直受区域经济发展不平衡的制约。基于此,本文从区域经济学角度出发,分析了区域经济发展与城市化进程的关系,并提出了加快城市化进程的相关建议。     

发展环渤海旅游圈的模式选择

区域经济合作是21世纪世界经济的突出特点，尤其是被誉为“朝阳工业”的旅游业正在成为我国各地政府大力扶植的支柱产业。环渤海旅游圈的建立，可以为环渤海区域经济的合作与发展起到支撑与拉动作用。环渤海旅游产业的联合互动和开发适宜区内的旅游新产品是环渤海地区今后旅游经济发展的趋势。     

我国区域经济结构升级的大系统战略及其定位

长期以来,区域经济的发展在我国一直是国民经济和社会发展进程中的一个重大问题。从本质上看,区域经济发展水平和可持续能力的高低,不仅牵涉到国家综合国力在全球竞争的胜负,也影响到本地区乃至全国的政治稳定和社会进步。改革开放以来,我国区域经济虽有很大发展,但东中西三大地带的经济发展仍很不平衡,差距突出。面对这种情况,确立新世纪我国区域经济结构升级的大系统战略及其宏观微观定位,便非常重要和迫切。从我国区域经济发展现状和产业布局的演变走势出发,在21世纪初叶,我国经济结构和产业结构调整的战略必须兼顾系统性、综合性和全局…

依托新亚欧大陆桥促进徐连经济带发展

新亚欧大陆桥作为我国继沿海、沿江经济地带之后的另一经济热点地区，正成为第三大经济地带，发挥承东启西的作用。改变着我国区域经济发展的格局，成为中国21世纪新的经济增长点，徐连经济带则是经济增长点中的重点区域，位于沿海、沿江、沿线（新亚欧大陆桥）的节点位置，如何充分利用区位优势，特别是利用陆桥的交通、流通优势，对促进地区经济的发展尤为重要。     

Privatization when the public firm is as efficient as private firms

The literature on mixed oligopoly shows that when production costs are quadratic the public firm is privatized if the competition in the product market is high enough. Similarly, when the public firm is less efficient than private firms and the marginal costs of production are constant, the government privatizes the public firm if its efficiency is low enough. In this paper we analyze this issue assuming that the public firm maximizes the weighted sum of consumer surplus, private profit and the profit of the public firm. If all firms have the same marginal cost of production we obtain that for some value of parameters the government does not privatize the public firm regardless of how many private firms are competing in the product market. We also obtain that the consumer surplus can be lower in the mixed oligopoly than in the private oligopoly.     

Communism as the unhappy coming

We show that Eastern Orthodox believers are less happy compared to those of Catholic and Protestant faith using data covering more than 100 countries around the world. Consistent with the happiness results, we also find that relative to Catholics, Protestants and non-believers, those of Eastern Orthodox religion have less social capital and prefer old ideas and safe jobs. In addition, Orthodoxy is associated with left-leaning political preferences and stronger support for government involvement in the economy. Compared to non-believers and Orthodox adherents, Catholics and Protestants are less likely to agree that government ownership is a good thing, and Protestants are less likely to agree that getting rich can only happen at the expense of others. These differences in life satisfaction and other attitudes and values persisted despite the fact that communist elites sought to eradicate church-going in Eastern Europe, since communists maintained many aspects of Orthodox theology which were useful for the advancement of the communist doctrine. The findings are consistent with Berdyaev’s (1933, 1937) hypothesis of communism as a successor of Orthodoxy.     

Collateralized Debt as the Optimal Contract

In a multiple-good risk-sharing environment with ex post private information, conditions are found under which collateralized debt is the optimal contract. The necessary and sufficient condition is that the borrower values the collateral good more highly than does the lender; otherwise the optimal contract does not resemble debt. Limited collateral can give rise to an endogenous borrowing constraint, driving a further wedge between the intertemporal marginal rates of substitution of the borrower and the lender.

Public capital in the 21st century: as productive as ever?

The global financial crisis and the euro area sovereign debt crisis that followed induced a rapid deterioration in the fiscal positions of countries across the globe. In the ensuing fiscal adjustment process, public investments were severely reduced in many countries. How harmful is this for growth perspectives? Our main objective is to find out whether the importance of public capital for long run output growth has changed in recent years. To this end, we expand time series on public capital stocks for 20 OECD countries and estimate country-specific recursive vector autoregressive (VAR) models. Results show that the effect of public capital shocks on economic growth has not increased in general, although results differ widely between countries. This suggests that the current level of public investments generally does not pose an immediate threat to potential output. Of course, this could change if low investment levels are sustained for a long time.     

新型城镇化进程中县域创新能力建设重难点与推进对策

提升县域创新能力对我国城镇化建设特别是农村就地就近城镇化建设具有非常重要的推动作用。县域创新能力主要由创新环境、创新条件和创新服务体系等多种因素构成。在新型城镇化建设背景下,推动高新技术成果转化和让企业成为创新主体是县域创新能力建设的难点与重点。推进县域创新能力建设需要营造良好的县域创新环境,整合并充分利用现有的科技资源,建设具有县域特色的产业集群,培育和引进创新科技人才,构建科学、动态的评价指标体系。     

Markets as beneficial constraints on the government

We study the role of anonymous markets in which trades cannot be monitored by the government. We adopt a Mirrlees approach to analyze economies in which agents have private information and a benevolent government controls optimal redistributive tax policy. While unrestricted access to anonymous markets reduces the set of policy instruments available to the government, it also limits the scope of inefficient redistributive policies when the government lacks commitment. Indeed, the restrictions that anonymous markets impose on the optimal fiscal policy, especially on capital taxation and the history-dependence of income taxation, can have positive welfare effects in this case.     

我国成为世界制造中心的思考

20 0 2年 8月 30日至 9月 5日 ,沈阳成功举办首届中国国际装备制造业博览会 ,这次大会共签约利用外资项目 1 2 6项 ,总投资额 2 7 4 4亿美元 ,其中外资额 2 4 78亿美元。这表明 ,我国装备制造业企业正加速与国际接轨。当越来越多的产品打上“中国制造”的字样走向全球时 ,有人惊呼 :中国已成为“世界工厂”。今天的“中国制造”不仅改变着中国的面貌 ,同时也赢得世界的尊重。本文便是我们参考沈阳制博会相关报道而成     

品牌作为进入壁垒的经济学分析

进入壁垒是新厂商进入特定产业（市场）所面临的一系列障碍,它是影响市场结构的重要因素。传统产业经济学研究的进入壁垒一般基于厂商的非对称优势壁垒（如规模经济、产品差异化等）或制度性壁垒（如政策、法律等）。但是,在高度市场化和宏观产业政策一定的条件下,非对称优势和制度性因素都无法真正成为阻碍厂商进入的壁垒。在消费者选择条件下,由品牌构筑起的进入壁垒将成为厂商竞争最重要的壁垒形式之一。
