"大沈阳经济区"的构建与辽宁老工业基地的振兴

大沈阳经济区是指沈阳与周边经济社会活动有密切联系的地区所形成的“区域经济共同体”.它的建立对于振兴东北老工业基地具有重要的战略意义.但在建立这一经济区的过程中也不可避免的存在一些问题,这需要通过一体化运作、机制创新等有效途径来加以解决.     

企业变异下的监管困境

股份公司产权的变化使得企业生产目的的两重性矛盾尖锐化,在相关条件的配合下,企业的矛盾就会在证券市场上,通过企业违规和股民投机的方式表现出来。而来自内部和外部的监管,也会由于一些一般性的原因而陷于困境。     

商品流通与产业升级的关系研究：理论与实证

商品流通与产业升级是两个密切联系的概念,商品流通对产业升级的影响主要是通过对社会财富的增量与存量调整来实现的。本文通过建立基于新兴古典经济学的理论模型,分析商品流通的发展所引起的交易效率的提高对产业升级的影响,然后利用我国的经验数据对两者进行协整分析、误差修正模型检验和因果关系检验。结果表明:我国的商品流通与产业升级之间存在长、短期稳定的正向关系,通过G ranger因果关系检验,我国的商品流通的发展是产业升级的G ranger原因,而反之却不成立。     

影响英语教学改革的因素

语言是交流的工具，语言教学起着至关重要的作用。随着社会经济、化以及科学技术的飞速发展，英语教学中旧的教学方式也得随之变化，以适应社会发展的需要。改革势在必行，但受到诸多因素的影响，改革效果不太明显。

Terrorism and its impact on economic growth and technological innovation

Recent terrorist acts, in particular the 9-11 attacks in 2001, have created disruptions in the global economy. The short-term impact had been felt in the global tourism, airline industries, as well as the financial markets. While the global economy has recovered and is adjusting to the new global realities, the longer-term impact of heightened security risk across the world can be felt in the form of higher risk premiums in asset markets, as well as a shift of resources towards dealing with terrorism. Just as World War II had accelerated the development of nuclear energy as well as a major contributing factor in the genesis of Silicon Valley, the current war against terrorism will affect both the pace and trajectory of technology trends, as efforts are focused on developing technologies to combat terrorism. In this paper, we review the effects of the current war on terrorism in terms of its impact on the economy, the allocation of resources to R&D, and the trajectory of future R&D.     

Does Gibrat's Law hold among young,small firms?

According to Gibrat's Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the examined period. Aimed at extending this line of investigation, the present paper uses quantile regression techniques to test whether Gibrat's Law holds for new entrants in a given industry: that is for new small firms in the early stage of their life cycle. The main finding is that for some selected industries in Italian manufacturing Gibrat's Law fails to hold in the years immediately following start-up, when smaller firms have to rush in order to achieve a size large enough to enhance their likelihood of survival. Conversely, in subsequent years the patterns of growth of new smaller firms do not differ significantly from those of larger entrants, and the Law therefore cannot be rejected.JEL Classification: L11, L60Previous versions of this paper were presented at the 27th Annual EARIE Conference (Lausanne, 7-10 September 2000) and at seminars held between 2000 and 2003 at the Economics Department of Harvard University, the Catholic University of Milan, the University of Ferrara, the University of Bologna, the Bank of Italy, and Athens University of Economics & Business.

衰退产业中企业创新战略选择

衰退产业是一种越来越普遍的产业形态。产业创新是衰退产业中企业的生存选择。衰退产业创新有三种基本战略,即进攻型创新战略、防御型创新战略和模仿与依赖型创新战略。     

Endogenous innovation and imitation in a model of equilibrium growth

This paper provides a growth model in which innovation as well as imitation occurs. Economic growth is due to product innovations. Innovators driven by the possibility to appropriate monopoly profits do not remain in their monopolistic position forever. Latecoming imitators get into possession of the private knowledge of production through investments in R & D. Imitated products are marketed in oligopolistic markets. Imitation proves to be profitable despite a single factor market and positive imitation costs. A steady-state equilibrium with positive imitation and innovation rates as well as different market structures can be derived. Finally, the effects of industrial policy measures are discussed.     

地区专业化的度量

在封闭经济假设和地区间需求结构一致假设下,本文构造了地区专业化的度量指标——地区专业化系数;这一度量指标更具一般性,产业结构差异系数、空间分布差异系数、绝对利差及行业分工指数等指标只是作为它的特例而存在。在讨论地区专业化问题时,如果忽略地区的(或行业的)相对规模因素,除了犯有逻辑推理错误外,在实践中还存在着可能得出错误判断的倾向。本文发现:中国工业的地区专业化水平自20世纪80年代中后期以来有了较大程度的提高;如果忽略地区的(或行业的)相对规模因素来讨论中国工业的地区专业化问题,则会高估中国工业的地区专业化水平。
