A functional approach for studying technological progress: Extension to energy technology

This paper extends a broad functional category approach for the study of technological capability progress recently developed and applied to information technology to a second key case—that of energy based technologies. The approach is applied to the same three functional operations—storage, transportation and transformation—that were used for information technology by first building a 100 plus year database for each of the three energy-based functional categories. In agreement with the results for information technology in the first paper, the energy technology results indicate that the functional approach offers a stable methodology for assessing longer time technological progress trends. Moreover, similar to what was found with information technology in the first study, the functional capability for energy technology shows continual—if not continuous—improvement that is best quantitatively described as exponential with respect to time. The absence of capability discontinuities—even with large technology displacement—and the lack of clear saturation effects are found with energy as it was with information. However, some key differences between energy and information technology are seen and these include:

?

Lower rates of progress for energy technology over the entire period: 19-37% annually for Information Technology and 3-13% for Energy Technology.

?

Substantial variability of progress rates is found within given functional categories for energy compared to relatively small variation within any one category for information technology. The strongest variation is found among capability progress among different energy types.

?

More challenging data recovery and metric definition for energy as compared to information technology.

These findings are interpreted in terms of fundamental differences between energy and information including the losses and efficiency constraints on energy. We apply Whitney's insight that these fundamental differences lead to naturally modular information technology artifacts. The higher progress rates of information-based as opposed to energy-based technologies follows since decomposable systems can progress more rapidly due to the greater ease of independent as opposed to simultaneous development. In addition, the broad implications of our findings to studies of the relationships between technical and social change are briefly discussed.     

Evaluating latecomer growth in information technology: A historical perspective

From a low initial base it is not difficult for developing countries to close the relative digital divide with the developed countries. A more challenging and novel question is whether, because of leapfrogging and other latecomer advantages, developing countries have grown faster than developed from the same initial starting point. Or, is it the case rather that the disadvantages of being a latecomer exceed the advantages? Are there any pronounced outliers among the developing countries and what are their distinguishing characteristics? Using a number of methods and data sources I seek to answer these questions in a tentative but provocative manner.     

技术进步的“体现观”与技术收敛测度指标构建

技术进步在经济增长与区域经济协调发展中的动力作用一直是人们关注的话题。区域间技术收敛是实现区域间经济收敛的必要条件。文章从经济增长理论中技术进步的分类出发,剖析了外生与内生、体现式与非体现式、资本偏向和劳动偏向等概念之间的关系,进一步给出了技术收敛的测度指标体系。文章认为,当前关于技术内生和外生的研究并没有与技术进步的"体现观"结合起来。新古典增长理论中所指的技术进步主要是非体现式的技术进步。内生增长理论中的体现式技术进步主要是体现在资本或劳动力中的技术进步。所以,技术收敛的分析应该在经济收敛分析方法的基础上,充分考虑体现在资本和劳动力中的技术和没有体现在要素中的技术,建立相应的测度指标体系。这种测度技术收敛的方法与一般性的技术收敛测度相比具有明显的优点,对相关的产业技术政策、人力资本流动政策以及产业转移等政策的制定具有重要的指导意义。     

A patent-based cross impact analysis for quantitative estimation of technological impact: The case of information and communication technology

The increasing syntheses and interactions between various technologies increase the usefulness of cross impact analysis (CIA) as a method for forecasting and analyzing them. Conventional CIA depends on an expert's qualitative judgment or intuition and thus it is difficult to evaluate quantitatively the impact of one technology on another. In this study, we employ patent analysis in CIA to examine such impacts between technologies based on multiple patent classifications. Patent information is used for facilitating quantitative and systematic approach in CIA. The distinctive feature and main contribution of the proposed approach is the overcoming of the limitations of conventional CIA, by employing conditional probabilities based on the patent information. The classification of patents, particularly the multiple classifications, is used to evaluate the relationships between technologies. As an illustration, a patent-based CIA with information and communication technologies (ICTs) was conducted. Firstly, the patent-based cross impact among ICTs was calculated. Secondly, the technology pairs were classified based on the cross impact score between ICTs. Thirdly, a cross impact network was constructed to identify the complex relation among ICTs. Finally, the changes in cross impact scores between technologies over time were analyzed. The results of this research are expected to help practitioners to forecast future trends and to develop better R&D strategies.     

The economic contribution of information technology: Towards comparative and user studies

By what process does technical change in information technology (IT) increase economic welfare? How does this process result in increases in welfare at different rates in different countries and regions? This paper considers existing literature on measuring the economic benefits from information technology, emphasizing comparative issues and user studies. Following Bresnahan and Trajtenberg (1995), we call the invention associated with customizing the technological frontier to the unique needs of users in particular regions “co-invention”, placing emphasis on understanding how its determinants vary across users in different regions. We develop a framework for understanding the processes behind value-creation, demand-side heterogeneity and co-inventive activity. Then we discuss why these processes make measuring the welfare benefits from advances in information technology particularly difficult. We highlight the metrics currently available for measuring the economic pay-out of the IT revolution and identify which of these vary meaningfully in a comparative regional context. Finally, we finish with observations about further areas of research.     

Localized technological change, new information technology and the knowledge-based economy: The European evidence

This work analyzes the co-evolution of new information and communication technologies and the knowledge-intensive business industry. New information technology affects the actual conditions of information, its basic characteristics of appropriation and tradability, favouring the role of business services as forces of interaction between knowledge components in the generation of new technology. Empirical analyses, based on input/output statistics of the European economy in the second half of 1980's, demonstrate the existence of a correlation between the usage of business and communication services and confirm their high output elasticity.     

Dynamic technological learning trends in Turkish manufacturing industries

Efficient development of industries requires a broad range of technological capabilities which can be acquired only by a long process of learning. Continuous measuring and monitoring of the ever-changing technological learning would be useful for building technological capability and managing technological policies. Nevertheless, research on how to measure the technological learning over time at macro levels remains largely untouched. In this paper, by adding the experience curve into the multifactor productivity part of Neoclassical production function, we will develop a model which will allow one to estimate the technological learning levels over long periods. This model would allow a user to both estimate the past learning experiences and forecast its future path on a time varying basis. The model has been used and tested in the estimation of the annual technological learning values for 28 Turkish manufacturing industries from 1981 to 2000.     

Diversity of technology acquisition in technological catch-up: an industry-level analysis of Chinese manufacturing

Using panel data analysis for an industry-level sample of Chinese manufacturing industries from 2000 to 2009, the study examines how latecomers dynamically adapt technology acquisition strategy in terms of technology acquisition diversity during the transition process from imitation to innovation. Our research considers technology acquisition as a portfolio of technology channels and thus examines the impact of technology gap between domestic firms and foreign firms on technology acquisition strategy at the industry level. The findings reveal that technology gap positively affects technology acquisition diversity of Chinese manufacturing industries. Further, it shows that technological uncertainty weakens the positive impact of technology gap on diversity of technology acquisition.     

R&D spillovers, information technology and telecommunications, and productivity in ASIA and the OECD

This paper examines the role research and development (R&D) plays in technology progress for a sample of OECD and Asian economies from 1980 to 1995. An empirical model is estimated which relates total factor productivity to domestic and foreign R&D activity, trade, and information technology and telecommunications (ITT). Model estimates confirm a positive relationship between national productivity and R&D activity exists in the long run. Further, the benefits of R&D can spillover countries through trade, in particular, trade in ITT equipment.     

Technological innovation strategy: how do technology life cycles change by technological area

Discussions on the patterns of technological innovation have significant implications in terms of the efficient distribution of national R&D resources and the establishment of corporate managerial strategies. This study is focused on calculating and analysing technology cycle time (TCT) by technological area based on patent data that can be used as easily accessible objective indicators for the purpose of modelling the patterns of technological innovation by period and technological area. The main technological areas handled by the study include medical science, vehicles, metallurgy, and computing. Of the patent data registered with the United States Patent and Trademark Office from 1990 to 2014, International Patent Classification sub-class codes representing each technological area were selected to collect patent data, and to generate TCT statistics every five years. The TCT statistics generated is interpreted as the technological life cycle, to be used in modelling technological innovation patterns individualised by technology and period.     

Globalization of technology: Network analysis of global patents and trademarks

This study explored how the structure of globalization of technology via intellectual property networks has changed longitudinally, and compares the structures of global trademarks and patents. It suggests that network analysis provides useful tools for describing recent trends in the globalization of technology. Network analyses describe which countries have higher technological capabilities, and also how countries are mutually connected for technological collaboration or transfer. In addition, network analysis confirmed that both the trademark and patent networks have become decentralized over time.     

Technological progress and regress in pre-industrial times

This paper offers micro-foundations for the dynamic relationship between technology and population in the pre-industrial world, accounting for both technological progress and the hitherto neglected but common phenomenon of technological regress. A positive feedback between population and the adoption of new techniques that increase the division of labor explains technological progress. A transient shock to productivity or population induces the neglect of some techniques rendered temporarily unprofitable, which are therefore not transmitted to the next generation. Productivity remains constrained by the smaller stock of knowledge and technology has thereby regressed. A slow process of rediscovery is required for the economy to reach its previous level of technological sophistication and population size. The model is employed to analyze specific historical examples of technological regress.

Markets, bureaucracies and groups in the information society : An institutional appraisal of the impacts of information technology

The issue regarding the impact of information technology on organizations is here reconsidered by applying a new analytical framework. Information technology affects the cost of transactions which take place under alternative institutional arrangements, such as markets, bureaucracies and groups; technology can affect the efficiency of the organizations which apply it and the organizational behaviour of their members. Empirical data show how computerization changes organizational patterns according to efficiency considerations. An enlargement of the framework to take into account alternative mechanisms for organizational participation, such as exit, voice and loyalty, allows to examine the impacts of information technology on participation possibilities within organizations.     

Linking technology innovation strategy,intellectual capital and technology innovation performance in manufacturing SMEs

The research interest on Intellectual Capital (IC) has been increasing, adopting different definitions and developing diverse measurement tools. Nonetheless, little research focuses on small and medium-sized enterprises (SMEs) and the relation between IC and innovation management. The purpose of this paper is to investigate the role of technology innovation strategy on the IC development and then on innovation performance in manufacturing SMEs. After conducting a survey, measures of IC for SMEs have been performed and an integrated structural equation model has been created. Results demonstrate that technology innovation strategy affects all IC components, the internal structural capital supports the relational and human capital, and the latter two influence firm technology innovation performance. This study contributes to developing an IC measurement system in SMEs and to emphasise the importance of single IC components in improving technology innovation performance.     

Information and communication technology diffusion and skill upgrading in Korean industries

We examine the relationship between the directly observable indicator of new technology, information and communication technology (ICT) investment intensity, and skill upgrading by analyzing changes in employment and wage structure of 25 Korean industrial sectors over the 1993–1999 period. The estimation results indicate the following implications. First, although ICT expenditure and investment have increased sharply since 1993, it appears that ICT investment has begun to be complementarily combined with skilled labor only since 1996. Second, our results support the ‘limited substitution hypothesis’. ICT has substituted low-skilled non-production workers, whereas the increased demand for high-skilled workers is driven by ICT diffusion in the second sub-period. This asymmetric trend between high-skilled and low-skilled non-production workers in Korea reveals significant differences in comparison with the experiences of other OECD countries. Third, the existence of substitutability between ICT diffusion and low-skilled non-production workers in Korea may cast doubt on the appropriateness of the non-production workers' category, a category regarded as a proxy variable of high-skilled workers in most previous studies.

Technological innovation and knowledge network in Asia: Evidence from comparison of information and communication technologies among six countries

South Korea, Taiwan, Singapore, Hong Kong, China and India have become much larger force in the world economy. Due to the enormous contribution of the use of information and communication technologies (ICT) in economic growth, this study investigates four main issues related to technological innovation and knowledge network in ICT among six countries. First, indicators of technological innovation were evaluated and used to compare capability of technological innovation in ICT between the six countries. Secondly, differences in innovation configurations among six countries were manifested. Thirdly, relative innovation strengths of these six countries were examined in five sub-technological fields. Finally, this study consists of analyzing the interactions into knowledge network among them; moreover, this study manifests the difference of knowledge network in five sub-technological field of ICT. The empirical findings of this study, based on analysis of a patent and citation dataset comprised of all patents granted by the U.S. Patents and Trademark Office (USPTO) to assignees in six countries from 1976 to 2006, are helpful to understand the comparative development of technological innovation of ICT in six countries.     

Technological diversification and assimilation of spillover technology: Canon's scenario for sustainable growth

Under the paradigm shift from an industrial society to an information society in the 1990s, contrary to the decrease of profits in Japan's electrical machinery firms, only Canon demonstrated its increasing trend. This contrasting performance corresponds to Canon's another contrast with respect to increasing technological diversification while reverse trends in other electrical machinery firms. These contrasts suggest us that Canon's technological diversification strategy can be the source of high level of its profits.Prompted by this hypothetical view, this paper analyzes Canon's scenario for sustainable growth and attempts to elucidate its technological diversification dynamism with special attention to its contribution to high level of profits. On the basis of the identification of the correlation between technological diversification and assimilation of spillover technology, comparative empirical analyses are conducted focusing on the consequence of technological diversification and development trajectory in Japan's leading electrical machinery firms over the last two decades.
