1991- 2005 : FDI来源结构变化的实证分析     

杨永华 《华南师范大学学报(社会科学版)》2006,5(5):43-49,72

1991- 2005, 中国的FDI来源地结构变化如下: 港澳台FDI在90年代前半期大幅度上 升, 1997年开始减少; 港澳台FD I占中国的份额从1991年的67%下滑至2004年的37%。韩国东盟维尔京群岛的FDI迅速增长, 占中国的份额从1991年不到2% 上升到2004年37%。美日英法德意加等发达国家FDI的绝对量有所上升, 占中国的份额稳定在20%左右。其余140多个国家和地区的FD I占中国的份额稳定在10%强。今后一段时期内, 中国FD I的规模及来源结构可能趋于稳定。  相似文献

A man on the inside: Unlocking communities as complementary assets     

Linus Dahlander 《Research Policy》2006,35(8):1243-1259

Since Teece's seminal paper explaining who were the gainers from technological innovation, increased globalization and the information and communication technology revolution have brought new ways for firms to organize and appropriate from innovation. A new more open model of innovation suggests that firms can benefit from sources of innovation that stem from outside the firm. The central theme of this paper is how firms try to unlock communities as complementary assets. These communities exist outside firm boundaries beyond ownership or hierarchical control. Because of practices developed by communities to protect their work, firms need to assign individuals to work in these communities in order to gain access to developments and, to an extent, influence the direction of the community. Using network analysis we show that some software firms sponsor individuals to act strategically within a free and open source software (FOSS) community. Firm sponsored individuals interact with more individuals than interact with them, and also they seek to interact with central individuals in the community. However, we can see differences in how individuals interact, depending on whether their affiliation is with a dedicated FOSS firm or an incumbent in the software industry. Apparently, some firm managers believe they need ‘a man on the inside’ to be able to gain access to communities.  相似文献

Copyright or copyleft?: An analysis of property regimes for software development   总被引：3，自引：0，他引：3  

Paul B. de Laat   《Research Policy》2005,34(10):1511-1532

Two property regimes for software development may be distinguished. Within corporations, on the one hand, a Private Regime obtains which excludes all outsiders from access to a firm's software assets. It is shown how the protective instruments of secrecy and both copyright and patent have been strengthened considerably during the last two decades. On the other, a Public Regime among hackers may be distinguished, initiated by individuals, organizations or firms, in which source code is freely exchanged. It is argued that copyright is put to novel use here: claiming their rights, authors write ‘open source licenses’ that allow public usage of the code, while at the same time regulating the inclusion of users. A ‘regulated commons’ is created. The analysis focuses successively on the most important open source licenses to emerge, the problem of possible incompatibility between them (especially as far as the dominant General Public License is concerned), and the fragmentation into several user communities that may result.  相似文献
