【摘要】：針對(duì)現(xiàn)代市場(chǎng)中廣泛存在廠商先后進(jìn)入的情況,基于Hotelling模型構(gòu)建了線性市場(chǎng)上二次運(yùn)輸成本下兩廠商水平競(jìng)爭(zhēng)的完全序貫決策模型,其中先進(jìn)入市場(chǎng)的廠商先選址再定價(jià),隨后跟隨者先選址再定價(jià)。兩廠商的博弈分析表明:跟隨者具有后發(fā)優(yōu)勢(shì),將獲得更大的利潤(rùn);先進(jìn)入者將定位在市場(chǎng)端點(diǎn),并采取低價(jià)策略;跟隨者將定位在市場(chǎng)中心,并采取高價(jià)策略。進(jìn)一步對(duì)所建的完全序貫決策模型、兩廠商先后同時(shí)選址與定價(jià)的博弈模型、兩廠商先同時(shí)選址再同時(shí)定價(jià)的博弈模型、兩廠商先同時(shí)選址再先后定價(jià)的博弈模型進(jìn)行了對(duì)比分析,研究結(jié)果表明:完全序貫決策與兩廠商先后同時(shí)選址與定價(jià)的決策一致,且定價(jià)和廠商利潤(rùn)均較低;4種博弈順序下兩廠商水平競(jìng)爭(zhēng)均衡都難以實(shí)現(xiàn)社會(huì)福利最大,需要政府"有形的手"發(fā)揮作用。
[Abstract]:Based on Hotelling model, a complete sequential decision model of horizontal competition between two firms in the linear market under secondary transportation cost is constructed, in which the firms that enter the market are located first and then priced. The follower then selects the site and then sets the price. The game analysis of the two firms shows that the follower has the advantage of late development and will gain more profit; the first entrant will be positioned at the end of the market and will adopt the low price strategy; the follower will be positioned in the market center and will adopt the high price strategy. Furthermore, for the established complete sequential decision model, the game model for the two firms to locate and price at the same time, and the game model for the two firms to locate and then price at the same time. The results show that the complete sequential decision is consistent with the decision of the two firms to locate and price at the same time. Moreover, the equilibrium of horizontal competition between the two firms is difficult to achieve the maximum social welfare under the four kinds of game order of lower price and lower profit, which requires the government's "tangible hand" to play its role.
