A Comparison of Technology Firms in Beijing and Shenzhen

Beijing and Shenzhen are both well known for their high-tech industries. This paper compares the financial performance of the two cities＇ technology firms and explores the effects of the firms＇ operating characteristics and strategy choices on their performance. We find that when comparable samples are used, the firms in Beijing performed better than those in Shenzhen. In addition, for firms both in Beijing and Shenzhen, the ratio of current asset to total asset had a significantly positive effect while both short-term and long-term debt-asset ratios had a significantly negative effect on the performance. The strategy variable sales expenses as a fraction of the cost of goods sold had a significantly positive effect on the performance of firms in Beijing, but the positive effect on firms in Shenzhen was not significant. R＆D inputs contributed significantly to the pre-tax profitability of Beijing firms, but bad no significant effect whatsoever on Shenzhen firms.

Modeling the dynamics of firms' technological impact

Recent studies in complexity science have uncovered temporal regularities in the dynamics of impact along scientific and other creative careers, but they did not extend the obtained insights to firms. In this paper, we show that firms' technological impact patterns cannot be captured by the state-of-the-art dynamical models for the evolution of scientists' research impact, such as the Q model. Therefore, we propose a time-varying returns model which integrates the empiricallyobserved relation between patent order and technological impact into the Q model. The proposed model can reproduce the timing pattern of firms' highest-impact patents accurately. Our results shed light on modeling the differences behind the impact dynamics of researchers and firms.

Appropriation of Innovation and Patent Behaviors of Technological Firms in the Yangtze Delta Area

In the transition from ＂made in China＂ to ＂invented in China,＂ what is the motivation of Chinese firms in applying for patents？ Why do some firms bypass patents？ How is patenting developing within Chinese firms？ This paper attempts to answer these questions using data of Chinese firms in the Yangtze River Delta region. Results indicate that, for product innovation, obtaining the lead time for market entry is of top priority in innovation protection, followed by confidentiality and patent protection. As for process innovation, confidentiality ranks first, followed by patent protection and obtaining the lead time. There is a significant and positive relationship between prior experience of patent licensing and possibility of future patent licensing. Firms with painful patent litigation experience tend to avoid it in the future. It is also found that there are great differences in patent behaviors between Chinese enterprises and their foreign counterparts.
