海洋经济可持续开发目标保证体系的探索

21世纪，人类将运用高科技对海洋资源进一步有效地开发，但在开发利用的同时又存在对海洋资源的破坏、污染问题。应如何建立可持续开发利用海洋资源的产业目标保证体系问题进行了较深入的探究。     

Wage inequality, technology, and trade

The recent widening of wage inequality has been attributed by some to skill-biased-technical-change and by others to trade liberalization. This paper examines the two explanations within a unified model and also presents a new modeling of skill-biased-technical-change, where skilled workers replace unskilled ones. As a result technology adoption is endogenous and does not occur in all countries. Hence, wages for both types of workers, trade patterns and also factor productivities in all countries are endogenously determined. The model sheds light on the relationship between technology and trade, on the reasons for global productivity differences and on the causes for the recent rise in wage inequality.     

Jointness in production and farmers' willingness to supply non-marketed ecosystem services

This paper highlights how farmers' willingness to supply non-marketed ecosystem services (ES) is influenced by whether or not the non-marketed ES are produced jointly with agricultural products. When marketed products and non-marketed ES share some production inputs the production relationships between the two may be complementary, competitive or substitutive. Using a cost minimization framework, it is shown how complementary relationships lead to costless voluntary provision of non-marketed ES (typically the case for ES that are supportive of provisioning ES for marketed farm products). It is also shown how competitive production relationships lead to provision of non-marketed ES at lower cost than when non-marketed ES are direct substitutes for farm products or are produced outside of agriculture. The paper closes by showing how the minimum willingness to accept (WTA) payment for ES that are complementary/competitive is less than or equal to the minimum WTA for the same ES produced in substitute or independent production relationships.     

我国现行环境政策调整与出口产品“环境竞争力”的提升

加入WTO后,我国要在该组织框架下接受贸易自由化与环境保护两股潮流的双重挑战,应对发达国家层出不穷的绿色贸易壁垒。如何合理调整国内现行的一些与WTO规则相矛盾的环境政策,提升出口产品的环境竞争力,促进我国经济与社会的可持续发展,将是我国加入WTO后急需解决的新问题。本文在对环境竞争力概念进行分析的基础上,界定了影响环境竞争力的主要因素。从国际、国内两个方面论述了当前我国环境政策所面临的挑战,及其调整方向。进而,提出今后提高我国出口产品环境竞争力的对策建议。     

Fiscal Shocks and the Current Account in the Redux Model: Evidence from the Italian Economy

The main goal of this paper is to study the effects of fiscal policy on the current account in the Italian economy through the analysis of one of the most innovative intertemporal models of recent years, the Obstfeld–Rogoff Redux model. The author proposes an innovative econometric approach to the model, based on the estimation of the microeconomic parameters that appear in its fundamental equations. The estimated parameters are used to empirically determine the multipliers that, according to the theory, connect permanent and temporary variations in public expenditure to the current account. Estimation is carried out on a dynamic extension of the original model, which has been developed modifying the first order conditions system of the maximization problem. Finally, the author provides a comparison between the results obtained and the actual dynamics of the Italian current account balance.     

技术性贸易壁垒内涵辨正

进入21世纪以来，技术性贸易壁垒替代反倾销成为我国面临的第一大非关税壁垒。但是对于技术性贸易壁垒，世界贸易组织框架下的相关协议，即《技术性贸易壁垒协议》和《实施卫生和植物卫生措施协议》，并没有做出明确的定义。因此，在分析世贸组织相关协议和判例的基础上，提炼出技术性贸易壁垒的内核，以对技术性贸易壁垒的含义加以澄清并重新认识，对于我国具有重大而深远的意义。     

Do exporters have anything to learn from foreign multinationals?

International technology diffusion through FDI has been examined mainly at macro or industry level whereas micro studies have been concerned mostly with spillovers. Using recent data on the UK manufacturing firms, this paper uncovers evidence that acquisition FDI is an important channel of direct technology transfer from foreign multinationals to domestic exporters. This finding accords with the prediction of the internalisation theory of FDI which postulates that multinational firms transfer a range of intangible proprietary assets to their affiliates.     

对马克思按分配原则的反思

马克思的劳动价值论不仅是剩余价值的理论基础和分析资本主义分配的理论依据，同时也是马克思设想的社会主义按劳分配的逻辑起点。只是以往我们对按劳分配原则的最本质的含义理解不够透彻。实质上，应该说马克思设想的按劳分配原则最本质的内容包括三点，即在未来的社会主义社会中，个人消费品的分配以劳动量的大小为依据，等量劳动获取等量报酬，承认能力本位。在社会主义市场经济条件下的按劳分配原则，仍然没有偏离这三点本质的含义，但已经有了新的特点和形式。     

Foreign direct investment, competition and industrial development in the host country

This paper analyses the impact of foreign direct investment (FDI) on the development of local firms. We focus on two likely effects of FDI: A competition effect which deters entry of domestic firms and positive market externalities which foster the development of local industry. Using a simple theoretical model to illustrate how these forces work we show that the number of domestic firms follows a u-shaped curve, where the competition effect first dominates but is gradually outweighed by positive externalities. Evidence for Ireland tends to support this result. Specifically, applying semi-parametric regression techniques on plant level panel data for the manufacturing sector we find that while the competition effect may have initially deterred local firms’ entry, this initial effect has been outpaced by positive externalities making the overall impact of FDI largely positive for the domestic industry.     

中国发展知识经济的空间结构

发展知识经济可以有效解决中国所面临的诸多挑战。文章探讨了经济发展的空间结构理论、城市与现代经济的关系、中国发展知识经济的路径选择,提出中国发展知识经济的空间结构是“升岛成陆”,即以各级有条件的城市特别是大城市为主先行发展知识经济,然后带动其它地区,扩大发展知识经济的区域,从而最终像地球科学中的升岛成陆造地运动一样,实现全国发展知识经济。同时,要通过行政区划制度创新促进这一进程,要将一些大城市升格为直辖市。
