As an effort to peek into the black box of large-scale general purpose technologies (GPTs) like biotechnology and information technology, we develop the concept of ‘anchor technologies’. An anchor technology is a core technology of a large-scale GPT (‘mega-GPT’) that opens a new era in the development and diffusion of the mega-GPT. We trace the historical evolution of two process-based, yet otherwise very different, anchor technologies: enterprise resource planning (ERP) software within the mega-GPT of information technology and polymerase chain reaction (PCR) DNA replication within the mega-GPT of biotechnology. The case studies reveal the utility of ‘productisation’ as an important means of commercialising innovations in anchor technologies; more generally, the interplay between improvement in process-based technologies and in complementary product-based technologies provides insight into how ERP and PCR were able to sustain a path of continued improvement within their respective mega-GPT.  相似文献

It is widely recognized that the adoption of energy saving innovations can induce an increase in the usage of the corresponding technologies and thus can possibly increase energy consumption. Among other concerns is that uncertainties regarding the magnitude of this “rebound effect” can deter policy makers from promoting energy efficiency. This paper analyzes the rebound effects of the adoption of energy efficient technologies in commercial buildings. Based upon a structural model of technology adoption and subsequent energy demand at the building level, the empirical results are that energy efficiency can reduce electricity use by about 35 % and natural gas consumption by about 50 %.  相似文献

In this paper, we analyze the consequences of biotechnology innovations in the United States forest sector (logging) by modeling technology transfer embodied in trade flows and its absorption. A seven-region, seven-traded-commodity version of a dynamic computable general equilibrium model is used to achieve this task. A 0.63% Hicks-neutral biotechnological progress in the source region (U.S.) has differential impacts on the productivity of the log-using sectors in the domestic as well as in the recipient regions. Since recipient regions' ability to utilize biotechnology innovations depends on their absorptive capacity (AC) and structural similarity (SS), we construct the AC and SS indices based on multiplicity of factors such as human capital endowments, skill content and social appropriateness of the new innovations. The model results show that biotechnological innovations in the U.S. forest sector result in a significant increase in timber production. Following the productivity improvements and its embodied spillover, wood products and pulp and paper sectors in the U.S. register higher productivity growth. The role of AC and SS in capturing technical change is shown to be evident. In the face of growing regulations on timber production from public forests, increasing productivity through biotechnology may be the most effective way to meet the consumer demand for forest products.  相似文献

The literature on the modeling of diffusion of technologies typically uses historical data to calibrate a model. For cases where data on the diffusion of comparable technologies are not available and where high multi-sector stakes are involved, models that use more specific information may be useful. The potential transition to alternative transportation vehicle technologies and fuels, like fuel-cell vehicles and hydrogen, would be an example of such cases. We propose an integration of theoretical frameworks on the diffusion of innovations with data on stakeholders' opinions, to develop estimates of FCVs' market-share evolution. Our estimates of the time scales required for the market, particularly for the initial stages, are longer than those obtained in other studies.  相似文献

Since the works by the business cycle theorists in the 1930s, no attempts have been made to study empirically the long term evolution paths of individual technologies starting with long time series. This is an empirical exploration and confirmation of the now almost assumed image or metaphor of the way technology develops; that it follows an S-shaped growth path which is commonly associated with a similar shaped diffusion function of entrepreneurial activity. The paper also confirms the diversity of technology dynamics and explores how technological cycle takeoffs appear to be clustered within certain historical epochs. The results have implications for our understanding of the evolution paths of individual technologies, and of the evolution of technological systems and waves of innovation. By use of computational statistics, logistic growth functions are fitted to US patent stocks, 1920–1990, at a detailed level of aggregation, including chemical, electrical/electronic, mechanical, transport and non-industrial technologies. Some practical considerations when developing an empirically testable model of innovation cycles are addressed in the paper as well.  相似文献

By exploiting a rich firm level data-base, this paper presents novel empirical evidence on the effect of process and product innovations on productivity, as well as on the role played by R&D and fixed capital investment in enhancing the likelihood of introducing innovations at the firm level. Our results imply that process innovation has a large impact on productivity. Furthermore, R&D spending is strongly positively associated with the probability of introducing a new product, whereas fixed capital spending increases the likelihood of introducing a process innovation. The latter result might reflect the fact that new technologies are frequently embodied in new capital goods. However, the effect of fixed investment on the probability of introducing a process innovation is magnified by R&D spending internal to the firm. This implies that R&D can affect productivity growth by facilitating the absorption of new technologies.  相似文献

We propose a framework to study the impact of information and communication technology on growth through its impact on organization and innovation. Agents accumulate knowledge to use available technologies and invent new ones. The use of a technology requires the development of organizations to coordinate the work of experts, which takes time. We find that while advances in information technology always increase growth, improvements in communication technology may lead to lower growth and even to stagnation, since the payoff to exploiting available technologies through organizations increases relative to the payoff from developing new innovations.  相似文献

This paper studies intellectual property rights (IPRs) and innovation in developing countries. A model is developed to illustrate the trade-off between imitating foreign technologies and encouraging domestic innovation in a developing country's choice of IPRs. It is shown that innovations in a developing country increase in its IPRs, and a country's IPRs can depend on its level of development non-monotonically, first decreasing and then increasing. Empirical analysis, with a panel of data for 64 developing countries, confirms both the positive impact of IPRs on innovations in developing countries and the presence of a U-shaped relationship between IPRs and economic development.  相似文献

This paper develops a growth model in which product cycles arise endogenously from investment in incremental and breakthrough innovations. Incumbent firms invest in incremental technology improvements with the aim of reducing production costs. Market entrants develop breakthrough product designs in order to capture the market from vintage product lines. The competing objectives of the two types of innovation generate product cycles within an environment of creative destruction, as new products displace old and are then manufactured using production technologies that are continuously refined. Investigating the relationship between innovation incentives and the average length of product cycles, we characterized three stable patterns of product evolution: incremental innovation alone, breakthrough innovation alone, and product cycles with both types of innovation. Numerical examples suggest that when the market exhibits stable product cycles, subsidies to either type of innovation raise the rate of economic growth and improve welfare.  相似文献

If technological roadmapping is important in the process of rapid technology commercialization, and if a method tailored to roadmapping nascent disruptive technologies does not exist, and if these very same disruptive technologies portend to be the future economic engines for firms, countries, and regions, then there is cause for concern. This article seeks to shed some light on the process in industrial disruptive technology roadmapping by focusing on the fundamental differences between sustaining and disruptive technologies. This article investigates the utility of theoretical and practitioner traditional technology roadmapping tools in an international industrial roadmapping effort focusing on microtechnology and top-down nanotechnology. I then modify the traditional technology roadmapping approaches generating a model for an industrial worldwide disruptive technology roadmapping process. I utilize the International Industrial Microsystems and Top-Down Nanosystems Roadmap (IIMTDNR) effort, which included nearly 400 people, from nearly as many firms, from over five continents and was developed over a 5-year period. The IIMTDNR process is used to provide the basis for a model for a commercial disruptive technology roadmapping process.  相似文献

Income inequality and the development of environmental technologies   总被引:1,自引:0,他引:1  
Within rich countries, a large dispersion in the capacity of generating environmental innovations appears correlated to the level of inequality. Previous works analyze the relationship between inequality and environmental quality in a static setting. This paper builds a dynamic model more suitable to analyze technological externalities driven by the emergence of a new demand for green products. Under fairly general assumptions on technology and preferences, we show that: 1. the relationship between inequality and environmental innovation is highly non-linear and crucially depends on per-capita income; 2. an excessive inequality harms the development of environmental technologies especially in rich countries. Key to our results is the fact that externalities generated by pioneer consumers of green products benefit the entire population only for relatively low income distances. The empirical analysis robustly confirms our theoretical results, that is: whereas for rich countries inequality negatively affects the diffusion of innovations, per-capita income is paramount in poorer ones.  相似文献
