Context matters: How existing sectors and competing technologies affect the prospects of the Swiss Bio-SNG innovation system

Emerging technological fields are affected by developments in their broader context. This article proposes a differentiation of context structures as a crucial step in the analysis of technological innovation systems. A thorough context analysis, so the argument, is essential for understanding the pace and direction of technology development and the prospects of an emerging technological innovation system. Empirical insights are provided for Bio-SNG, a technology in an early stage of development. The article discusses the conditions under which actors from different sectors (forestry, wood industry, and energy supply) may play a role in the emerging field. It is shown that Bio-SNG is likely to become a victim of the recent boom in wood-to-energy technologies that has favored investments in more mature but technologically inferior alternatives. The case provides lessons for policy making as it highlights how effective support schemes might foster a lock-in into technologies that are readily available.

Innovation,Diffusion and Cumulative Causation: Changes in the Spanish Growth Regime, 1960–2001

This article presents a model of macroeconomic growth that combines in a single formalization two complementary views on innovation and economic growth, the technology‐gap approach and the Kaldorian theory of cumulative causation. The model suggests that what matters for economic growth in the long run is the existence of a good match between the patterns of technological change, income distribution and demand growth. The model is estimated for the Spanish economy during the period 1960–2001, and the econometric results show that important changes have happened in its growth regime over time. Since the 1980s, innovation and diffusion of new technologies provide a greater stimulus to productivity growth, but the technology push on the supply‐side is not sustained by the prevailing patterns of income distribution and demand growth.     

A systematic approach to identify core service technologies

In spite of the importance of service technologies in the service industry, they have not been analysed systematically. In response, this study proposes a new approach to identify core service technologies. At first, the technological interrelationship matrices from the perspectives of intensity, relatedness, and cross-impact are constructed with support, lift, and confidence values calculated by conducting an association rule mining on the co-classification information of business method patent data. The analytic network process is applied to the constructed technological interrelationship matrices in order to produce the importance values of service technologies from each perspective, considering their direct and indirect interrelationships. Data envelopment analysis is then employed to the derived importance values in order to identify core service technologies, putting three perspectives together. The proposed approach can be utilised for both firms’ planning of service technologies and service innovation policy-making of governments.     

新技术进步会阻碍传统技术创新吗——来自汽车产业的实证检验

在新旧技术竞争过程中,传统企业会适时调整研发策略,以应对新技术进步对传统技术造成的冲击。然而,新技术对传统技术的影响究竟表现为创新替代效应还是创新互补效应,至今依然没有得到确切结论。以汽车产业为研究对象,比较传统燃油汽车和电动汽车两种新旧技术的发展路径,并结合产业生命周期理论提出汽车产业的三阶段演化模型。进一步基于1995—2021年省级专利数据和面板向量自回归模型,从产品创新和工艺创新两个维度实证检验各阶段电动汽车技术进步对传统汽车企业创新的影响。结果表明,在电动汽车产业的范式导入期(1995—2008年),新技术通过产品创新和工艺创新两方面促进传统技术发展;在电动汽车产业的范式构建期(2009—2021年),新技术依然对传统技术有显著推动作用,但仅通过工艺创新促进传统技术发展。

低碳经济已经成为国际经济发展的新要求,因此,低碳技术开发日益受到世界各国的重视。太阳能技术是一种典型的低碳技术,我国经过10几年的发展,在太阳能领域取得了举世瞩目的成就,但因缺乏核心技术,目前面临着严峻的挑战。由于专利分析能客观地评价技术创新与合作水平,因此,为更好地促进我国太阳能技术的发展,基于专利分析法,对我国太阳能合作专利数据进行了分析。结果表明:我国太阳能技术的跨机构技术联系较少,"产学研"创新体系尚不成熟;政策扶持对于太阳能这种新兴低碳技术有较大的影响力;国内太阳能专利授权的技术领域主要集中在太阳能热利用,而在光伏领域的合作较少;太阳能合作专利存在较大的区域差异,应该进一步加强区域之间的技术合作和技术转移:应该加强国际技术合作。     

Coping with Technology Divergence Policies and Strategies for India’s Industrial Development

Recent studies on innovation have demonstrated the relationship between technology and growth. However, as most of them are centered on the experience of the highly industrialized nations, a different approach to technology policy must be taken. As late industrializers, developing countries lag in adopting foreign technologies. Institutional factors and economic policy also influence the diffusion process. With decentralized decision making, the coexistence of diverse technologies in a given industrial branch is inevitable. Consequently, social costs tend to be high because of duplication of efforts, reduced learning opportunities, and adoption of inefficient technologies. This article examines the coexistence of diverse technologies leading to technology fragmentation in India’s steel industry. Recent innovative behavior in the Japanese and Korean steel industry indicates that the effects of fragmentation can be contained through a policy of “system integration.” This is an institutional process by which industry-specific applications of scientific knowledge are fused with basic research itself. This demands a forward-looking policy that rejuvenates older industries, such as steel, in socially acceptable ways and organically creates new knowledge for national development and social welfare.     

Effects of re-invention on industry growth and productivity: evidence from steel refining technology in Japan, 1957–1968

This paper examines the economic impact of re-invention – the degree to which an innovation is modified by user – on industry growth and productivity. The paper focuses on two re-inventions made by a Japanese steel company; these inventions improved the productive efficiency of Austrian-made refining technology, namely basic oxygen furnace (BOF). Results obtained from the plant-level production function estimation indicate that re-inventions account for approximately 30% of the total factor productivity of the BOF, substantially promoting the dissemination of the BOF technology. Our simulation analysis indeed reveals that re-inventions contributed to steel output growth by about 14%. This paper also documents that innovating companies played the role of a ‘lead user’ in developing and disseminating their re-invented technologies.     

Unveiling the core technology structure for companies through patent information

Patent information provides an objective and public source to understand core technologies of companies. In this paper, a method is proposed for identifying core technology capabilities for a company in the semiconductor industry. The method is built on the patent similarity and K-means clustering algorithm. The indirect relations among the patents in the complex industry are considered in the method. In addition, the age of the patent is taken into account to avoid identifying aged core patents. The method is demonstrated by exploring the core technology capabilities that support the platform technology portfolio of the Taiwan Semiconductor Manufacturing Company (TSMC).     

Analysis of open innovation communities from the perspective of social network analysis

Open innovation is an emergent paradigm by which organisations make use of their internal and external resources to perform their innovation processes. The growth of information and communication technologies has facilitated the spread of online open innovation communities, where users can share ideas as well as comment on and evaluate ideas posted by other community members. In this work, the behaviour of community members is analysed from the perspective of social network analysis. The final aim is twofold: first, to measure to what extent the different forms of participation are correlated to each other; and, second, how the collective intelligence evaluation schemes can be useful to identify those users posting ideas which are potentially applicable for the organisation. Obtained results can help community managers and organisations to improve the efficiency of the evaluation process when hundreds or thousands of ideas are shared through the online community.     

制造业技术创新策略：技术水平与技术来源选择

制造业技术创新离不开合理的技术来源选择，而选择技术来源必须考虑行业实际技术水平，这样才能更有针对性地促进技术创新。鉴于此，采用2003—2019年我国制造业细分行业面板数据，按照技术水平进行分组回归，实证检验不同技术来源对不同技术水平行业技术创新的影响。研究表明，自主研发对以专利为代表的技术创新存在显著促进作用，且在高技术行业中的作用更突出；对于以发明专利为代表的实质性创新，自主研发仅在非高技术产业样本中存在创新激励作用，在高技术产业样本中，技术引进则发挥显著促进作用。进一步分析不同技术来源对技术创新经济效益的影响发现，国外技术引进和国内技术购买会抑制技术创新经济效益增长，而技术改造和自主研发会促进技术创新经济效益增长，且其作用效果在低技术行业中更为显著。结论可为我国制造业细分行业针对性选择技术来源、优化技术创新策略提供现实依据。

Generic innovation dynamics across the industrial technology life cycle: Platform equation modeling of invention and innovation activity

We describe here a generic approach to innovation dynamics based on an integrated framework for inventions and innovations applied via a platform equation and model across the industrial technology life cycle. We test the model for metals and other materials, and demonstrate that this model correctly describes the production activity for several materials and energy conversion technologies.Innovation activity patterns are shown for several oxides, metals, oil and wind energy and its derivatives. The metals Cu, Al, W, Mo and Pb are particularly studied for the amount produced over time. The total activity for the metals encompasses both the invention and innovation stage for a particular metal. Four major stages and two sub stages are identified for the discovery (invention) and subsequent growth regimes (i.e. the innovation stage). The pattern equation appears to clearly capture all these stages for the metals studied — work is ongoing for similar analyses of energy and other materials. Although the metals studied existed over differing periods (e.g. copper greater than 200 years whereas aluminum, just over 100 years), one single pattern equation appears to capture all the major trends. The use of the model is also shown for productivity analysis, especially for the condition of radical innovation (very rapid growth). For sustained radical innovation, namely, when the output of the produced material per unit time, keeps on increasing with time, there are various factors which may influence growth. For the conditions where thermal activation and plant size are the dominant variables, their impact on the growth may be examined in the context of the pattern equation. A preliminary analysis of oxide production activity also appears to follow this same innovation model.The results suggest a fertile field of future research extending the initial platform equation model to include R&D, Patents, and Performance, as well as Sales, as innovation activity. Further, the model shows promise in combination with the ARI methodology model for analysis and assessment of existing and future industrial technology life cycles involving material, process, product, software and service innovations.

基于K-means与技术生命周期的技术预见方法研究——以水体净化技术为例

预见水体净化技术发展趋势有助于实现“美丽中国”建设目标。已有技术预见方法缺乏定量客观依据,相关评判指标也不够全面。从Innography数据库检索2008-2019年发布的3552个污水处理技术专利,运用多维标度分析和K均值聚类法,基于专利静态指标分析专利技术发展潜力,采用技术生命周期分析法从动态视角判断每类技术的发展前景。研究发现：①污水与污染物双重回收可持续性技术在多个静态评价指标方面均优于其它技术,且处于从引入期到发展期的过渡阶段,具有较大的发展空间;②以去除特定污染物为目标的功能单一技术已被淘汰,市场开始应用污水处理原理不同的多种技术联合处理方式。据此,提出企业应选择污染物回收率高、二次污染物排放少、整体“净效益”为正的污水处理技术,并采取新旧技术联合处理方式降低企业采用新技术的转换成本。     

Cumulative causation in the formation of a technological innovation system: The case of biofuels in the Netherlands

Despite its worldwide success, the innovation systems approach is often criticised for being theoretically underdeveloped. This paper aims to contribute to the conceptual and methodological basis of the (technological) innovation systems approach. We propose an alteration that improves the analysis of dynamics, especially with respect to emerging innovation systems. We do this by expanding on the technological innovation systems and system functions literature, and by employing the method of ‘event history analysis’. By mapping events, the interactions between system functions and their development over time can be analysed. Based on this it becomes possible to identify forms of positive feedback, i.e. cumulative causation. As an illustration of the approach, we assess the biofuels innovation system in The Netherlands as it evolved from 1990 to 2007.     

绿色与非绿色技术对后续创新影响的比较——“厚此薄彼”还是“双赢策略”

尽管绿色技术一直被认为具有广阔的发展前景,但这些技术在企业间的扩散率却很低。企业在非绿色与绿色技术创新关系上存在“厚此薄彼”的现象。基于1992—2019年中国制造业上市公司专利数据研究发现,相较于非绿色技术,绿色技术的前向引用次数更多,且产生了更大的知识溢出效应,对整个社会后续创新具有更大的正向影响力。此外,由于高能耗行业存在转化成本高、自身知识储备不足等问题,随着能耗水平提升,绿色技术对后续创新的正向影响力逐渐减弱。相较于非国有控股企业,国有控股企业绿色技术对后续创新产生了显著正向影响。该结论对政府设计绿色与非绿色创新“双赢策略”,促进企业从“厚此薄彼”转向绿色与非绿色技术双创新具有重要意义。
