This paper examines the process of embodied technology spillovers in terms of supply and demand of technology For the purpose, this paper develops a consistent framework to estimate intersectoral R&D spillovers, and to pinpoint the sectors that are the most important for innovative activities and the sectors that produce most technologically intensive products. Based on an input-output framework, the technology intensity of fourteen sectors and the interaction between the sectors in terms of technology spillovers are measured. The results indicate that knowledge-based service sectors are highly supply-pulling and value-additive, but low in terms of employments. The study found that computer services, telecommunications, technology services, and art-related services are the most technology intensive sectors.

All over the world, the attention on the exploitation of public research, which is mainly implemented by technology transfer, has increased in recent years. Licensing, which is one of representative mechanisms for public-to-private technology transfer, is accompanied by the frequent conflicts in negotiating a license payment between public research institutes (PRIs) and private firms. In spite of the body of literature on technology transfer in a licensing context, it focuses on contracts between private firms. Even the existing literature, which addresses public-to-private technology transfer through licensing, to our knowledge, has not yet formalized an established licensing model. This paper develops a mathematical model of public-to-private licensing, not hitherto tried by academics. The model addresses important issues to be applied comprehensively in licensing practice, such as determining a royalty rate, balancing between an initial payment and a running royalty, designing an inventor's incentive system, and setting a minimum payment as a screening criterion. The paper also provides reasonable management implications to controversial issues in technology transfer from PRIs to private firms, partly employing the comparative analysis between current stylized licensing practice and the one suggested in the model. We hope that study contributes to providing the foundation on which the theory on public-to-private licensing would extend to an in-depth level.

This paper raises two questions about the overall national innovation system (NIS) in Korea, Japan, and Taiwan - (1) what has distinguished the three countries in terms of their NIS in the past and (2) why are the changes that are taking place now, relatively make the NIS in these countries similar to each other\ulcorner At present, the NIS of each country is becoming more privatized and flexible than the pre-financial crisis period. We argue that this assimilation is due to the free flowing technologies readily available in the international technology markets. We argue significant shifts in the NIS of these three countries, notably a move from a manufacturing-based NIS with a high level of protection, piracy, and stability to a venture-based NIS with high levels of flexibility, risk taking, and technological innovation.

This paper investigates the determinants of the firm's decision to carry out innovative activities in terms of the resource-based view(RBV) in strategic management. Two types of resources are distinguished: tangible(financial autonomy, firm size, capital intensity) and intangible(human resource, entrepreneurship, and commercial resource). R&D intensity and patent statistics are used as proxies for innovative activity. Specific hypotheses about their effect on the probability of a firm carrying out innovative activities are derived and tested on a sample of 337 listed firms in Korean manufacturing industry for the year 1999, using the logistic regression model. Empirical findings suggest that firm size and human resource are the main determinants of firm's internal innovative activities. The results show that the hypotheses concerning financial autonomy, debt ratio, capital intensity, entrepreneurship, and commercial resource are rejected.

This paper extends the empirical analysis on R&D based growth model so that the nonstationary panel unit root testing methods can be used to distinguish the exogenous growth model and R&D based growth model for the 1981-1999 period with fourteen OECD economies including Korea. Our results show that first, using U.S. and Group mean as benchmarking, the stochastic R&D productivity convergence to benchmarking is not supported in our data set. Second, the empirical results for stochastic nonconvergence to the U.S. or group mean also are robustness to panel unit root methods. We, therefore, find strong support for the implications for R&D based growth model.

Expansion and enhancement of information and communication infrastructure can create a market closer to an ideal type for a perfect competition, utilizing a cyber space in the network (with the expanded usage of Internet and e-commerce) and it could be a market of a monopolistic form. The government can take one of the two approaches responding to this monopolization of the digital market. First, the government maintains laissez-faire policy since the monopoly cannot be maintained over a long period of time due to an increasing in the production, decrease in the price, profit resulting from this and rapid technology evolution. Second, the government can actively interrupt the monopolization of the digital market. Monopolization in a digital market can lead to a market failure. Unstable market structure and too much frequent merger and acquisition contribute to making the digital market very dynamic. Information goods exchanged in the digital market have the features of very low marginal cost required to copy the original product whereas its initial fixed cost is very high. This explains why the information products are not priced based on the existing marginal price determination principles and why companies producing them have various product sales strategies (price/product differentiation strategy, and other sales strategies).

This paper explores how international political factors influence the role of conventional external factors in the course of technological learning. The research goes on to investigate whether the role of the techno-economic factors has changed due to the involvement of international political factors in the technological learning mechanism. To this end, this paper examines how US political intervention affected Korean technological learning in the back-end of the nuclear fuel cycle. The export policy, prior consent policy and international political influence of the US are employed as international political factors. The empirical findings show that international political factors are very likely to restrain the impact of the techno-economic factors on technological learning process. Accordingly, this paper hypothesizes that the role of techno-economic factors in the technological learning mechanism is weaker when international political intervention is involved.

In order to manage technology transfer properly, it is important to judge whether the technology transfer is successful or not, and to find out the reason of the conclusion. The study aims to find out the relationship between successfulness of technology transfer and reasons or basis of the conclusion. Empirical investigation was carried out for Korean small and medium size firm in machinery and material field with statistical analysis on questionnaire and intensive interview. Result of the analysis is identified and compared with the other. It is shown that Korean firms feel their technology transfer is successful when it meet functional objectives and to get enough knowledge to further utilization from external source. Realization of benefit do not affect much the successfulness of technology transfer even though it is final objectives of technology transfer.

A variety of methods of patent valuation are written in this paper. The typical methods such as scoring method, income approach method, market approach method, DCF method, real option method, are introduced in this paper and each of them is criticized respectively. A new method, so called "GVP Method", is introduced and shows how much effective it is when patent valuation is required. And specially MPEG patent licensing method is introduced in this paper.his paper.
