What best transfers knowledge? : capital, goods, and innovative labor in East Asia

This paper compares three knowledge carriers—trade, foreign direct investment (FDI), and inventors—as knowledge mediums, and investigates their effects on knowledge flow in East Asia from 1996 to 2010. Using patent citations as a proxy for knowledge flow, this paper shows that FDI and inventor mobility have positive effects on increasing patent citations in East Asia when the technological portfolios of two countries are less similar. While trade shows statistical significance, the effect is inconsistent according to the regression models

The innovation process of a privately-owned enterprise and a state-owned enterprise in China

This study compares the innovation process of a privately-owned enterprise and a state-owned enterprise in China using their patent data. Huawei and ZTE were selected for this study because they experienced the same historical environment in the same industry from the same region in China leaving their owner types as their critical difference. This study investigates the difference in the innovation process in R&D between a privately-owned and a state-owned enterprise by analyzing (1) domestic and international patent application pattern, (2) co-application and co-applicants, (3) knowledge accumulation inside Huawei and ZTE, and (4) knowledge spillover to domestic and foreign firms

PATSTAT revisited

This study provides a comprehensive summary of and guidance for using the EPO Worldwide Patent Statistical Database (PATSTAT), one of the most widely used patent databases for researchers. We highlight the three most important issues that PATSTAT users must consider when performing patent data analyses and suggest ways to deal with those issues. Although PATSTAT is chosen in this study, the issues that we discuss are also applicable to other patent databases

Mobility of highly skilled retirees from Japan to Korea and Taiwan

Attracting highly skilled workers is a major element for the economic development of many countries, especially developing countries. However, the general international mobility of workers is from developing countries to developed ones. Historical evidence has indicated that Korean and Taiwanese firms scout for highly skilled Japanese workers (either retired or soon-to-retire) to accrue knowledge and achieve catch-up. Therefore, this paper investigates how the highly skilled Japanese workers were scouted by firms in Korea and Taiwan. Aiming at producing evidence rather than testing hypotheses, the findings of this paper shed practical information for firms in developing countries to attract highly skilled workers for their growth. In addition, this paper provides insights into the international mobility of highly skilled workers from a developed country to developing countries, which has not been examined in previous literature

Descriptive analysis of the knowledge network formation in East Asia

This paper shows descriptively how the knowledge network in East Asia has been formed. In addition, the correlation between the knowledge network and economic growth is also examined. Evidence is provided to show that plugging into the knowledge network of developed countries could be a key for increasing innovativeness in a country

The impact of import vs. export competition in technology flows between countries

Many countries are interested in strengthening their technological capabilities to achieve high growth rates. Knowledge flow is a key to build technological capabilities. This paper investigates how competition in international trades affects knowledge flow between countries. There are two findings. First, the results in the current paper shows that import is indeed an important avenue for knowledge flow, conforming with the results from the previous literature. Second, what is interesting and new is that export competition in the third market (in our study, the US market) seems to also have a positive impact on the flow of knowledge. The finding from this study contributes to the debate on “learning-by-exporting”

Avoiding the middle income trap : indigenous innovative effort vs foreign innovative effort

This paper investigates how innovation potential of a country contributes to avoid or escape the middle income trap. We measure innovation potentials of 77 countries from 1975 to 2010 from patent data. Then, we test whether indigenous innovative efforts or foreign ones help avoid and escape middle income trap

Pilot study for essentiality assessment of Standard Essential Patents

This study investigates the technical and institutional feasibility of a system that ensures better essentiality scrutiny for Standard Essential Patents (SEPs). We first studied the state of the art on essentiality assessment in literature, court cases involving larger scale essentiality assessments, essentiality assessment in patent pools, and the Japanese Hantei for Essentiality advisory opinion. A patent landscape analysis of SDO declared patents was performed to assess their use as input to essentiality assessment mechanisms. Technical feasibility was assessed in a pilot experiment, in which a variety of assessors evaluated patents for their actual essentiality. Institutional feasibility was, among other means, assessed via a stakeholder workshop. Given (1) the observed interest in transparent data on essentiality of patents for standards, from implementers, patent owners and courts alike, (2) the potential benefits of such data for these parties and for the system as a whole, and (3) our finding that a system for generating such data seems both technically and institutionally feasible, we recommend policy makers to pursue the development and implementation of a system for essentiality assessments.JRC.B.6-Digital Econom
