日元升值对日本进出口贸易的影响及其对我国的启示

20世纪70年代以来日元升值与日本对外贸易的关系表明:从短期看日元剧烈升值对日本对外贸易造成一定的冲击,但日本政府和企业采取相应措施缓解了日元升值对其带来的负面影响,即通过调整产业结构、加强科技创新、发展对外直接投资等措施来化解矛盾;从长期看日元升值并没有给日本对外贸易的增长造成实质性影响。研究日元升值与日本对外贸易间的关系,对同样面临人民币升值压力的我国具有重要的借鉴意义。     

Influence of technological support,skills and competencies,and learning on corporate entrepreneurship in European technology firms

In the today′s changing environment, firms are hardly competing with each other to achieve a competitive advantage that can differentiate them from others and improve their organizational performance. In this sense, it is crucial to develop corporate entrepreneurship and promote strategic variables that foster it.The aim of this paper is to highlight the importance of different technological variables (top management support to technology, technological skills and technological distinctive competencies) and organizational learning on corporate entrepreneurship, and thus analyze the influence of corporate entrepreneurship on organizational performance in the context of technology firms.A sample of 160 European technology firms was selected from the database Amadeus in 2009 with CEOs as our main informants. The hypotheses studied are empirically confirmed by using a hierarchical regression model.     

科技创新竞争力研究

科学创新是企业技术创新和提升竞争力的前提条件，而技术创新是企业提升竞争力的物质载体，竞争力又是企业科学创新和技术创新的表现形式以及在竞争市场中发展壮大的关键，三者是相互作用相互制约的统一体。从三者内在逻辑关系阐述科技创新竞争力的基本内涵及其构成要素，并以此构建科技创新竞争力的理论模型。这为我国企业在全球竞争市场中提高优势地位赋予了理论价值与实践意义。     

亚洲四小技术创新及其启示

科技进步是当代经济增长的基本动力 ,而创新是科技进步的基本形式。亚洲四小龙——韩国、台湾、新加坡、香港 ,特别是前三者在技术创新方面走在了其他发展中国家的前面。本文主要是考察亚洲四小作为技术后来者怎样进行技术创新的 :1 通过技术学习、吸收和获取工业发达国家先进的科技成果作为创新的基础 ;2 把发展外向型经济同技术学习紧密结合在一起 ;3 技术学习和技术创新不断深化和提高 ,从简单到复杂 ,从低级到高级 ;4 沿着逆国际产品生命周期轨迹进行创新等等。亚洲四小技术创新的经验对其他所有发展中国家的经济都有参考意义

Dynamic Factor Demands and Technology Measurement under Arbitrary Expectations

We present a dynamic model of factor demands based on expected discounted costs minimization. While making only very mild assumptions on expectations and technology, we are able to establish a duality relationship between contemporary factor demands and the technology, and we provide formula for easily recovering marginal products, returns to scale, and technological change from estimated factor demands. Parametrization and implementation are illustrated in a detailed example.     

美国对华直接投资对中国技术进步和产业竞争力的影响

20世纪90年代以来美国对华投资发展迅速,投资规模不断扩大,在华子公司引进技术的水平也呈不断提高态势。从美国对华投资的特点来看,其主要集中在技术密集型和资本密集型产业。而且,美国对华投资以市场寻求型为主,研发当地化以适应国内市场的需求就成为其必然选择。本文将在简述美国对华投资企业技术特点的基础上,分析其对中国技术进步以及产业竞争力提升的影响,为中国在引资过程中趋利避害提供理论参考。     

技术外部性、工业集聚与地区经济的非均衡增长

经济增长的空间不平衡和路径依赖特征是近年来中国经济面临的重要问题。基于技术外部性产生的规模报酬递增，这篇文章从理论和经验上分析了技术外部性、工业集聚和地区经济非均衡增长之间的动态相互作用。分析结果表明，在逐渐成长起来的市场力量的作用下，这些因素动态相互作用产生的规模报酬递增延续和放大了地区间不平衡的工业化过程，从而导致了经济增长空间上的不平衡和地区收入差距时间上的持久性和自我增强的特征。     

The future of the mobile phone business

One of the fastest growing technologies of our times is that of mobile phones. In this article we use the assumption that the diffusion of mobile technology, as measured by the number of active mobile accounts, follows the well known S-curve of natural growth in competition systems. The accuracy of the logistic fit is tested against actual data for the whole world, Europe, China and the GSM system. Using the produced models predictions concerning the future of mobile business are deliberated.According to these models active mobile accounts around the globe are expected to grow from 1.7 billion in 2004 to approximately 2 billion in 2008, reaching a peak penetration of 29.2%. Growth barriers, apart from the age of the potential user, are also low income and extreme poverty. Europe, early adopter of mobile technology and leader in active mobile accounts against all other regions in the world, has apparently reached a peak with almost every European, apart from the very young or very old, using a mobile phone. The mobile market in China is anticipated to exceed 500 million active accounts and may increase even further depending on the economic and social reform that is currently under way in that part of the world. GSM will most likely remain the leading mobile technology in the future as it is today.The growth process for the world, Europe, and the GSM system is almost completed and during this stage instabilities may occur before the potential emergence of a new wave of growth.     

科技工作者的审美倾向与其问题发现和解决的相关性分析

采用"中国公民人文素质调查问卷",对全国1089名科技工作者的审美倾向与问题解决进行了相关性分析。结果表明:科学美对于科技工作者具有极为重要的方法论意义,但不具有本体意义;科技工作者的"艺术美"审美倾向与问题解决不具有直接的相关关系,推动科学问题解决的审美倾向是科学美审美倾向,推动科学问题发现的审美倾向是自然美审美倾向,并针对上述结果进行了相应探讨。
