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.

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 traps

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.

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.

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.
