Therefore, different relationships between oligopoly companies will lead to different responses in their decisions on R&D investment. A correlation deduced from different responses of oligopoly companies in R&D investment with the complete information tactic game theory is presented, and the R&D investment of oilfield service companies was analyzed with this correlation. The correlations of Schlumberger's R&D investment, Halliburton's R&D investment and Baker Hughes' R&D investment were established and analyzed. Meanwhile, two regression models were presented. One was composed of Schlumberger's R&D investment in the previous year and Halliburton's R&D investment. The other was composed of Schlumberger's R&D investment and Baker Hughes' R&D investment in the same year. The accuracy of these two models was proved to be good.展开更多

However,negative effect brought by the relationship capital should not be neglected,including distorting the social equity,increasing social transaction cost,and weakening the public trust in government. It is a top priority to effectively evade its negative effect and bring into full play huge potential of the relationship capital.展开更多
