Game About Mini Motor Industry Competitions Of Our Country

The motor industry have undergo many changes in the processes of developments in a hundred years. The changes reploued the automobile industry have grown up to big industry of world from the hardicraft profession .The core competition of the automobile enterprises which have undergone the changes. Continously get to promote with the variations of the property environment. The several transforms of the core of the world motor industry since a hundred years, show that no one can be the lead in the competition of this market forever, the techrical innovations bestow the same chances to every country, every region and every enterprise. Everyone who become the tops later have not develop as the predecessors. They explit and create their advantages according to their conditions, and they avoid and trans for their their shortages. They explore their own point of create and research the way to get the superiority of the later. This essay divided into three parts to discuss the competitions and development tendercy of motor industry, and analyze the conditions of the international mini automobile industry. Main of the processes and result as follows:In the first part, I introduce the basical models of the market competition of uniform quality product, under the circumstance which according with every assumption, realize to maximize the profits.The enterprise's profit is a liner function as:Πi(q1,q2)=(P(Q)-C)qiThis assume ption became the base of monopolist model which develop from Bortrand. Bortrand two tops market model described that the business enterprises have the same result under the policy of the price in the market of the same uniform quality products.The profit of the enterprise can be indicated to substract the production cost from profits of the sales, so: Π1(p1,p2)=(p1-c1)q1=(p1-c1)(a1-b1p1+d1p2)Π2(p1,p2)=(p2-c2)q2=(p2-c2)(a2-b2p2+d2p1)As , , so we can get the functions of the prices reflection:So tows points of intersection p1* p2*of the reflection functions is the Nash balance of this playing game model.In the actual it is not have only tow enterprises proceed the price competition of uniform quality products, so we must suppose there are n ent5erprises proceed the price competition in the market. Now the focus of the reflection curve give the Nash balance, it can be gotten to solve the following equations: li=ai+bici i=1,2,3nIn the second part, I analyze the price competitions of the mini automobile industry of our country, applying the spreaded Bortrand model of above. The main copetiters of the mini motor market of our country are Chang-an, He-fei and Wu-ling.Their manufactures and sales volume occupy over 80% of the market. So we can use the Bortrand model of price competition of three enterprises to analyze the competition of the mini automobile market of our country.The profits function of three business enterprises is : Πi(p1,p2,p3)=(pi-ci)qi (I=1,2,3)The price reaction function of three enterprises is : So we can get Nash balarcl price.I the third part, first, introduce the development and present conditions of international mini motor, Now the sales of mini motors is 1/3 of three sales of motor vehicles every year in Japan; In Europe, it is 35%,every year 4.5 millions mini motors have been saled ;In India, mini motor is one of the types which saled best, and many middle classesard petty bourgeoisies are keen on the mini motors; In Korea, for the influerce of the finance storm of Southeast Asia several years ago. Oil's price rising and economic depression, numerous consumers also turn to the mini motors whose prices are cheap.Secondly, I out look end the development thrdercy of the mini motor industry of our country, mainly for Chinese conditions; replacing the motor for agriculture; changing administration management system; shortage of energy; export ext. six aspects, it has vast development prospect. In the mini automobile industry if our country. In the output of 30%of the sum; In 2005, the o...
