安康翻譯公司關鍵字：technology spillovers. If the downstream firms are monopoly companies, midstream companies will worry about its technology spillovers, then the downstream monopoly firms will increase the growth of monopoly on the market, as buyers of products middle business monopoly. So that one day people will be restricted and, thus, when technology spillovers its reservations, the middle cross-trade business or seeking to explore other markets outside the region upstream and downstream enterprises of other technology spillovers. So for the downstream market, the optimal choice is perfectly competitive market.The above model analysis, in order to analyze the problem of convenience, assume that the upstream business is fully monopoly, oligopoly or monopoly midstream business is competitive, downstream firms are perfectly competitive. That along the chain from upstream to midstream, to downstream manufacturers continue to reduce the degree of monopoly, while competition is increasing. In this industrial structure, as a source of technology spillovers middle enterprises in the strongest preference for technology spillovers, technology spillover effects are the best. Without loss of generality the problem, as long as the chain, the monopoly on the middle and lower reaches along the chain from the sequential decline in the level of competition increased sequentially, we can draw the following conclusions as to promote the source of technology spillovers in oligopoly firms should or monopolistic competition in the market, which helps maintain the source of technology spillover companies use advanced technology. Arrangements in the company, you can choose the strength of domestic enterprises and foreign enterprises to enter the same industry, this technology spillover effect will be better, but with the strength of domestic industrial enterprises in the competition to learn through imitation and innovation of new technologies.
Conclusion 2: upstream raw materials or spare parts business is not necessarily a complete monopolist, but the degree of monopoly is higher than the level of competition is lower than the source of technology spillover business, so that the source of technology spillovers to upstream enterprise technology companies will overflow the strongest. High degree of upstream monopoly, the government invested in the main.
Conclusion Three: downstream firms are not necessarily completely competitive, but below the monopoly level, the level of competition is higher than the source of technology spillover business, so that the source of technology spillovers to downstream enterprise technology companies will overflow the strongest. Strong competitive downstream firms to private capital invested in the main. The resulting extension of the model (see Figure 2). Note: that chain direction; that the direction of
