美日技术创新的产业分布及其对贸易竞争优势演变的结构效应

本文借用固定市场份额法,通过实证得出:美日两国从上世纪80年代末开始,技术创新产业选择方向出现了明显的不同,从而产业结构(贸易结构)的转换出现了较大差异,美国结构成功转型,贸易竞争优势得到了明显的提高;而日本产业结构和贸易结构转型一直在摸索阶段,结构升级的缓慢是日本贸易竞争优势有所下降的内在原因。     

农业部门劳动力再配置、农村非农化与中国农村经济增长

文章通过在二元经济增长模型中引入内生经济增长思想的基础上,构建了一个能够较好地对中国农村经济增长进行模拟和解释的理论模型.整个模型将中国农村经济增长划分为传统农业阶段、非农产业发展阶段与"反哺"阶段三个时间段,并着重分析了农业剩余的出现与非农产业的发展,这也是中国农村经济改革之所以成功最为重要的一段时期.文章最终认为,农村经济发展的最终目的应该是促进农业与非农产业的协调发展,以推进社会主义新农村建设、构建社会主义和谐社会.     

提高高新技术企业技术创新能力的对策研究

高新技术企业是属于知识聚集和技术密集的企业,提高企业自身技术创新能力是高新技术企业赢得竞争优势的关键,更是推动高新技术企业走向快速发展的必然途径。本文系统的分析了技术创新对高新技术企业的重要意义,从外部大环境和企业内部自身环境所存在的不足而导致高新技术企业技术创新过程所存在的问题进行了客观的分析,列举了外部环境和内部环境在高新技术企业中所出现的具体问题,同时针对不同的问题提出了相应的解决对策并作出了有益的探讨,为高新技术企业技术创新的研究提供一定的理论研究,为高新技术企业走向高级化发展提供了借鉴经验。     

Endogenous technological progress and the cross-section of stock returns

I study the cross-sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. Technological progress is endogenously driven by research and development (R&D) investment and is composed of two parts. One part is devoted to product innovation; the other, to increasing the productivity of physical investment. The latter is embodied in new tangible capital. The model breaks the symmetry assumed in standard models between tangible and intangible capital, in which the accumulation processes of tangible and intangible capital stock do not affect each other. Qualitatively and, in many cases, quantitatively, the model explains well-documented empirical regularities.     

Organization of innovation and capital markets

This paper develops a theory of the firm scope where not only research but also ordinary production employees can generate inventions. Separating research from production (“specialization”) solves the two-tier agency problem of inducing simultaneously research effort and managerial truthful-reporting but is costly when capital markets are imperfect. Improvements in capital markets, therefore, promote specialization, allowing a greater number of specialized firms to be established and also enabling them to undertake innovative projects with larger potential outcomes. Moreover, this capital market improvement effect is stronger for innovative activities that are less capital-intensive and that have weaker synergies with existing production activities. The model can help us understand the explosion of small company innovation in the U.S. since late 1970s and the contribution of venture capital to this change.     

NPD speed vs. innovativeness: The contingent impact of institutional and market environments

Whereas new product development (NPD) speed and product innovativeness are two critical strategic determinants of firm performance, previous studies show inconclusive findings about their effects. Drawing on institutional and contingency perspectives, this study elucidates value appropriation issues in NPD and examines how the effects of NPD speed and technological radicalness are contingent on institutional frameworks and market conditions. Results from 244 high-tech companies in China show that dysfunctional competition enhances the effect of NPD speed, but legal inadequacy hinders the impact of technological radicalness on firm performance. Market growth strengthens the performance effect of NPD speed but restrains the effect of technological radicalness. In addition, technological radicalness demonstrates stronger effects on firm performance when demand uncertainty is high.     

Identification of technological structures using patent statistics

This paper studies the use of patent statistics in identifying four aspects of technological structure, namely, the potential knowledge pool, cumulativeness, inter-firm homogeneity in technology levels, and the scope of innovations. The firms are sampled from the chemical (CHEM), the computer (COM) and the electrical and electronic (EE) industries worldwide. Using the proxies defined, we find that (i) the contributions of intra-industry spillover are low, at 12%, 10%, and 9% for the three industries respectively; (ii) they can internalize 15%, 19% and 13% of their previous research efforts respectively; and (iii) a positive relationship between knowledge spillover and technology overlap, and between scope of innovation and number of patents being cited in future.     

技术创新与出口:理论与实证研究的发展

从理论阐释和实证分析两个方面述评技术创新与出口关系的主要观点和相关文献。众多相关文献表明,技术创新活动是一国出口表现的主要驱动力之一,在扩大市场、提升国际竞争力以及增加企业利润方面起着积极的促进作用。     

社会结构、市场结构与企业技术创新

本文建立了一个基于社会结构与市场结构的技术创新系统模型,来解释企业的技术创新行为,认为企业是社会网络中的一个行动者,其技术创新行为是一种社会行动,它会受到人际关系和社会结构的影响.作为一种结果,社会结构会影响市场结构,从而两者共同作用于企业的技术创新过程.在这个过程中,对企业的社会资本分析是非常重要的.推动社会结构、市场结构与技术创新活动的协调发展是深化我国经济体制改革进而提升企业技术创新竞争力的重要途径.
