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).     

A welfare analysis of global patent protection in a model with endogenous innovation and foreign direct investment

This paper constructs a North–South quality-ladder model in which foreign direct investment (FDI) is determined by the endogenous location choice of firms, and examines analytically how strengthening patent protection in the South affects welfare in the South. Strengthening patent protection increases the South's welfare by enhancing innovation and FDI, but it also allows the firms with patents to charge higher prices for their goods, which decreases welfare. However, the model shows that the former positive welfare effect outweighs the latter negative effect. Moreover, introducing the strictest form of patent protection in the South, that is, harmonizing patent protection in the South with that in the North, may maximize welfare in the South as well as in the North. Further, a similar result can also be obtained in a nonscale effect model.     

On the welfare implications of nominal GDP targeting

This paper examines the welfare implications of a nominal GDP growth targeting rule, a nominal GDP level targeting rule, and inflation targeting regime in a New Keynesian model featuring positive trend inflation, two measures of welfare, and both high and low growth environments. The paper finds that (i) in general, nominal GDP growth targeting dominates other rules with changes in all dimensions; (ii) nominal GDP growth targeting framework is superior to the level targeting regime for most scenarios; (iii) inflation targeting is preferred to nominal GDP level targeting regime, but to minimize short-run fluctuations, the latter is advantageous; (iv) nominal GDP level targeting may be desirable only in a low growth environment with both low inflation indexation and consumption equivalence criteria. The simulation results provide solid evidence to policy makers on the desirability of nominal GDP growth targeting.     

国际技术转移与我国技术创新

在经济全球化、一体化的背景下,跨国公司作为国际技术转移主体的作用正在不断增强,FDI的流入的确推动了我国的经济进步,但跨国公司为了维持其在某些领域的垄断地位,还会千方百计地阻挠这种技术的转移和扩散,加上我国自身的经济结构和体制的障碍及吸收学习能力的有限,技术转移的效应可能达不到理想的理论水平.因此,既要注重跨国公司的技术转移,又不能忽视我国的技术创新,这是实现经济可持续增长的根本所在.     

Optimal fiscal decentralization: Redistribution and welfare implications

The literature has been inconclusive regarding the welfare effects of fiscal decentralization (FD), defined here as the extent to which local governments collect and spend local tax revenues. We present an original model to investigate formally the distributional and welfare implications of FD. In contrast to the standard approach that compares the implications of full FD with that of centralization, we consider that the central government chooses the level of FD to maximize welfare in a heterogeneous country. Noncooperatively, local governments choose their tax collection effort to maximize local utility. We show that an increase in the tax rate leads optimal FD to increase so as to compensate for the welfare loss from decreasing optimal local tax effort. Hence, welfare and income distribution improve in FD at its intermediate, rather than extreme, levels. We coin this result as the decentralization-Laffer curve. As regional spillovers increase, FD is less desirable as it deteriorates welfare and income distribution. This finding provides a novel support for the decentralization theorem and contributes to the fiscal policy debate.     

Exploring technology diffusion and classification of business methods: Using the patent citation network

Among the many technology forecasting indicators, patents and patent citations are useful and important indicators. The more frequently a certain patent is cited by subsequent patents, the more the related technology can be said to be diffused, implying that the technology is more widely applied and thus more valuable. This paper analyzes the business methods technology which retrieves patents from the USPTO database. There are two purposes of this paper: 1. establish the indicators for finding basic patents and measure the relationship of these basic patents; 2. classify the basic patents and explain the groups of technology diffusion. Finally, this study identifies the two mainstreams in business method technology: one is focused on marketing technology, and the other one stresses on data security. Both are important for Internet data processes or e-commerce activities.     

Price competition,free entry,and welfare in congested markets

In this paper we study the problem of price competition and free entry in congested markets. In particular, we consider a network with multiple origins and a common destination node, where each link is owned by a firm that sets prices in order to maximize profits, whereas users want to minimize the total cost they face, which is given by the congestion cost plus the prices set by firms. In this environment, we introduce the notion of Markovian Traffic Equilibrium to establish the existence and uniqueness of a pure strategy price equilibrium, without assuming that the demand functions are concave nor imposing particular functional forms for the latency functions. We derive explicit conditions to guarantee existence and uniqueness of equilibria. Given this existence and uniqueness result, we apply our framework to study entry decisions and welfare, and establish that in congested markets with free entry, the number of firms exceeds the social optimum.     

Mapping technological development using patent citation trees: an analysis of bogie technology

We create a generational patent citation tree to reveal the development of bogie technology in the high-speed rail industry. We cull the information in patent citations to reveal the generational development of bogie technology by analysing patent titles, patent publication dates and patent-granting regions. We then measure the development of bogie technology by calculating its technological development on-orbit rate and by mapping the stages of technological development and its regional diffusion. The results show that bogie technologies are in a period of sustained growth and this period of sustained growth will remain. Technological development is accelerating and this acceleration will persist, although the global dispersion of technology lags behind in scope and speed.     

The framework for factors affecting technology transfer for suppliers and buyers of technology in Korea

To gain an ongoing competitive advantage over other firms, a firm must acquire new technology to differentiate itself from others. This paper explores the technology transfer of technology for information technology equipment and establishes a comprehensive framework for the factors which affect on-time completion of technology transfer for suppliers and buyers according to technology transfer agreements. The technology transfer process is divided into the categorical stages that take place. Then, experts’ opinions are analysed through analytic hierarchy process to determine the influential factors affecting on-time completion of technology transfer. The results of this study should provide a basis for firms to evaluate on-time completion of technology transfer and a reference for the technology transfer process for both suppliers and buyers.     

Monitoring the organic structure of technology based on the patent development paths

As the strategic importance of understanding changes in technology for successful business of most firms increases, the ability to analyze and monitor the current stage and history of technology is reckoned as a critical asset both for gaining competitive advantage and identifying promising niches. Patent citation networks have been widely used for systematic and empirical analysis of technology development. Understanding of technology's detailed changes in large patent citation networks, however, is difficult to achieve because of these networks' large and complex structures. To overcome this problem, we suggest an algorithm that identifies patent development paths from a large patent citation network by evaluating the weight of citations between patents. We then apply this algorithm to flash memory patents in an empirical study. Our algorithm is a new methodology that can be used to analyze the dynamic and complex structure of individual technologies.     

A heuristic procedure to identify the most valuable chain of patent priority network

In this study, we provide support for the argument that patents are at their maximum value at those times when they are under litigation. We develop a heuristic procedure to determine the way in which such patents under litigation form a network of patent family members, and then go on to examine the priority patents involved. We subsequently attempt to develop a simple procedure to further identify both the ‘critical’ and ‘significant’ chains within our proposed patent priority network. We suggest that the ‘critical’ and ‘significant’ chains that are created within the above network provide companies with important information which will ultimately provide them with valuable support for the subsequent decision of their patent portfolio strategies.     

Financing technology transfer: assessment of university-oriented proof-of-concept programmes

This study analyses the characteristics of the proof-of-concept (POC) programmes initiated by university and public research organisations in Europe, as a mechanism to address funding gaps and improve the transfer of research-based inventions to markets. We contribute to the literature on investment readiness of new ventures and on financing technology transfer by assessing the structure of such funding instruments and identifying critical success factors for their design and implementation. The analyses rely on seven in-depth case studies of university-oriented POCs in Europe.     

Household-level analysis of the impacts of electricity consumption on welfare and the environment in Cambodia: Empirical evidence and policy implications

Cambodia’s biomass consumption is the most dominant energy source at residential sector, and its use is mainly for cooking and heating which could affect health due to indoor air pollution. The biomass is mainly sourced from wood cutting and forest-encroachment that could impact the environment due to reduction of forest at considerable scale. By using the data 2015 of Cambodia Socio-Economic Survey, the study investigates the impacts of electricity consumption on household welfare, such as earnings and the school performance of children in the households, and further to investigate its impacts on the environment. The study found that household’s access to electricity with ability to spend on electricity consumption contributes to the positive household welfare effects and environment via a reduction of biomass consumption, and the more household spends on biomass, the more they are prone to sickness of lung problem. The study also confirmed the important role of human capital formation for the positive impact on the welfare and the environment. These findings lead to policy implications that would improve affordable access to electricity to ensure that all households can use electricity for their basic needs and productivity, and also to reduce the negative effects on environment.

The impact of technology transfer on agribusiness performance in Kenya

ABSTRACT

This study examines how technology transfer can influence the performance of small businesses in developing countries like Kenya. The theoretical basis of the study is the technology transfer model, which integrates a consideration of the transfer provider with that of the recipient’s capacity. The study’s sample comprises 104 enterprises. Correlation and a regression model are used for content analysis. The results show that technology transfers improve small businesses’ performance and help drive rural development. The effectiveness of transferred technology has a major impact on small businesses’ competitiveness and access to international markets. These findings imply that governments must develop technology transfer strategies for small businesses in order to enhance both their performance and food security. Government policies for technology transfer should incorporate incentives for agricultural technology transfer to boost food security.     

Types of patents and driving forces behind the patent growth in China

As a developing economy, China's unprecedented patenting surge is puzzling. We study China's patent surge and its driving forces using a novel and comprehensive merged dataset on patent applications filed by Chinese firms. We find that R&D investment, FDI, and patent subsidy have different effects on different types of patents. First, R&D investment has a positive and significant impact on patenting activities for all types of patents under different model specifications. Second, the stimulating effect of foreign direct investment on patent applications is only robust for utility model patents and design patents. Third, the patent subsidy only has a positive impact on design patents. The results imply that FDI and patent subsidy may disproportionately spur low-quality patents.     

Foreign capital and technology transfer in a dynamic model

We consider a dynamic three-sector dual-economy model when the technology transfer takes place from the foreign enclave to the labor-intensive domestic enclave. The long-run equilibrium and the comparative steady-state effects are analyzed. It is shown that the policy of subsidization to the foreign enclave may satisfy the conflicting tasks of raising national income and lowering unemployment simulataneously in the long run. Subsidization to a domestic enclave does not satisfy both the objectives.     

The welfare cost of imperfect competition and distortionary taxation

The welfare cost of imperfect competition in the product and labor markets in the United States is quantified in a dynamic general equilibrium model. We find that the welfare cost of imperfect competition in the product market is 3.62 percent while it is 0.58 percent in the labor market, taking the transition path from the distorted to the optimal steady state into account. If we also take into account that the US economy is characterized by distortionary taxation, the welfare cost of the product market distortion increases to 13.51 percent and the labor market distortion to 4.35 percent.     

Factors affecting technology transfer offices' performance in the Italian food context

In recent years, growing attention has been devoted to the commercialisation of knowledge and technologies developed by universities and public research institutions. A central role in this particular process is played by the technology transfer offices (TTOs), which are on the one hand in charge of promoting the transfer of knowledge and technology to external companies, and on the other hand are also responsible for protecting and licensing the intellectual property of the research organisation. This paper is focused on a TTO operating in the food context, with the specific objectives of identifying the performance indicators and the main factors affecting its performance and, finally, analysing the relationships among these factors. Results highlighted the importance of both external and internal factors for the performance of a TTO operating in this context. In addition, we found both direct and indirect relations within these factors.
