中美战略互信的困境与机遇

目前中美战略互信处于一种低度信任状态。增进中美战略互信,我们应该持有的预期不可能是高度信任,而只能是中度信任,因为中美战略互信存在结构困境、博弈困境和政治文化困境。但同时也应看到,由于中美关系完全失衡的状态正在发生根本性改变,中美经济关系正在朝着前所未有的深度和广度发展,中国的国际形象正处在一个最佳时期,中美之间的相互了解和交流已进入前所未有的高峰期,全球治理的挑战要求中美加强战略互信,中美战略互信进入重要机遇期。

The role of technological catch up and domestic market growth in the genesis of emerging country based multinationals

The paper presents a model that evaluates how upgraded technological capabilities of emerging country based multinationals (EMNCs) and an increase in the domestic market size of large emerging countries affect value chain location choices and the competitiveness of emerging country based firms versus advanced country based ones. The model shows that, even without possessing a competitive advantage in terms of technology and/or brands, EMNCs from large or rapidly technologically advancing countries can become dominant players in the global system. The model highlights the central role of firm level technological intensity and product differentiation in determining the location of value chain activities as well as defining organisational boundaries. Empirical analysis of the location choices of the world's top multinationals from large advanced and emerging countries in 2010 supports the model's predictions.     

Is small actually big? The chaos of technological change

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study the development of electronic displays from 1976 to 2010, using patent data. The results of the chaos model are matched against the profiles of patent citations. Our analysis contributes to the development of a chaotic model of technological change.     

Technological change in U.S. jet fighter aircraft

This paper quantitatively measures technological change in U.S. jet fighter aircraft from 1944 to the present day using the hedonic pricing approach. The technical and performance characteristics of jet fighters have changed dramatically between the time they were first developed at the beginning of the 1940s and the present. Parallel to this technological change there has been a sharp escalation in costs regarding the new generations of jet fighter aircraft. We estimate a measure of price for the performance and technical characteristics of these aircraft. Embodied technological change in jet fighter airframes is measured using quality-adjusted prices. Although the flyaway cost of jet fighter aircraft has soared, on average, by about 12.63% per year, the quality-adjusted aircraft cost has only risen by about 2.6% per year, a figure lower than the average observed general inflation rate for the period (around 4%). This represents an impressive average technological progress ratio of around 10% per year. A revealed preferences argument shows that the characteristic most valued by the government is stealth capability, followed by advanced avionics.     

Light emitting diodes and the lighting revolution: The emergence of a solid-state lighting industry

Emergence of new industries from evolving technologies is critical to the global economy, yet has been relatively understudied due to the paucity of available data. This study draws lessons on industry emergence, by analyzing how a solid-state lighting (SSL) industry grew out of light emitting diode (LED) technologies that evolved for half a century, with participation by tens of thousands of researchers in universities, national laboratories, and firms. Using data on publications, patents, and firms combined with business history we trace the evolution of SSL through a succession of market niches. At times a few researchers with unorthodox research approaches made breakthroughs that greatly advanced particular technology trajectories and pushed LED research in unexpected directions. A succession of LED market niches advanced the technology and provided profits to incentivize continuing research while reducing cost and improving efficacy of LEDs. Innovating firms developed a thicket of patents and captured substantial profit, but were embroiled in extensive litigation that was ultimately resolved through cross-licensing. A major new generation of lighting products is now disrupting the traditional lighting industry. Although the leading incumbent lighting firms all invested early and heavily in SSL, the industry's future leadership is uncertain.

基于科学的创新：研究回顾与展望

基于科学的创新是指强烈依赖于科学进展、由前沿科学知识推动的产业技术创新,包含了新想法的产生、研究、开发、试制、生产制造和首次商业化的全过程。时至今日,基于科学的创新受到了西方学者的重点关注,他们围绕西方情境进行了大量的理论探讨与实证检验。但由于研究比较分散,研究视角、层次、问题的差异,特别是缺乏系统的文献梳理,导致这一创新范式在国内还没有得到足够的关注和讨论。因此,本文采用系统性文献综述法,对国内外相关文献进行检索,共识别出英文文献258篇、中文文献52篇。基于这些文献,本文全面梳理了国内外基于科学的创新的研究脉络,包括相关概念、特征、过程与模式以及创新范式的演进。同时,本文从创新维和企业维梳理了基于科学的创新知识框架。最后,本文提出了未来潜在的研究方向,以期为后续研究提供参考。     

广东基础研究竞争力探究：基础研究产出视角

高水平科研论文是体现基础研究成果的主要载体。为科学把握广东在国内的科技竞争力地位,利用Access、CiteSpace等工具和波士顿矩阵分析方法,从论文产出、卓越论文、国际合作论文和学科优势等维度对2010—2019年广东SCI论文情况进行定量定性分析。结果发现：广东SCI论文数量全国排名第四、增幅居全国首位,论文被引用强度明显提升;但广东在SCI论文数量和质量,以及基础研究产出和学科建设方面,与北京、上海等地存在一定差距,发展仍较为滞后。广东建设更高水平的科技创新强省,要进一步加强对基础研究的重视、引入和培育优秀科技人员、再创学科新优势和打造高水平科技期刊等学术交流平台。
