Fitness And Market Structure Evolution Under Different Paths Of Technological Acquisition ——Evidence From Chinese SUV Automobile Market

The study of market structure is one of the core problems in the theory of industrial organization,which has been concerned by scholars.Recently,evolutionary economics scholars believe that the market structure is dynamic,who emphasize diversity,selection and development.The driving force of diversity comes from the competition among enterprises,which leads to the efforts of enterprises to realize the differentiation and explore the products which can produce competitive advantage.Therefore,evolution economics comes from a large number of biological metaphors and evolutionary ideas,which formed in practice,imitation,trial and error,limited rationality,path dependence and selection as the core category theory.It emphasizes competition heterogeneity of individuals in the population,market selection mechanism,different individuals have different fitness,which shows the difference of market share growth.Market selection is the process of changing the relative frequency of different individuals in the population.Therefore,evolutionary economics scholars often use market share to measure the evolution of market structure.Fitness on the one hand refers to learning process,on the other hand it refers to the results of competition.in the population.Previous studies on evolution of fitness and market structure are based on the developed countries,the emerging market countries obtain technology from different paths,fitness and market structure evolution mechanism needs further research.Therefore,this paper explores the impact of fitness of emerging market countries on the evolution of market structure under different technological acquisition paths.The main contents of this paper are as follows:（1）Fitness and market structure evolution,acquisition mode and its effect,different technology acquisition mode,respectively from the industry level and enterprise level and product level three aspects summarizes the fitness and the relationship between the market structure,further summarizes the different technology acquisition modes and different technology access mode and influence.（2）The technology acquisition paths are divided into two paths（replicator dynamic path）,we put forward the hypothesis of this study:first,for the whole population,fitness can promote the market share;secondly,different paths of technology acquisition,fitness has a different effect on market share.（3）We select all Chinese SUV as the research object,by using the data envelopment analysis to estimate product efficiency.We make empirical test on the relationship between fitness and market share.（4）The main conclusions of this paper are as follows:firstly,the diversity of innovative behavior leads products show different fitness in population competition,car models with considerably lower fitness than the market average lose additional market shares,whereas models with above-average fitness gain additional market shares.Secondly,for emerging markets,the relationship between fitness and market share are affected by technology acquisition paths,in the initial state the introduction of technology,through the introduction of key technologies,through reverse engineering,R＆D investment,local enterprises constantly improve the absorption capacity.The accumulation of innovation ability can respond quickly to the external environment,therefore,the initial state of the introduction of technology,fitness has a stronger effect on market share.In the initial state of joint,joint ventures only copy the production line,which continue to accumulate the process of the production capacity.Product development ability,innovation ability is limited,which can not respond quickly to the rapid development of new products to meet consumer demand.As a result,fitness has a weaker effect on market share.Due to the existence of path dependence,the different initial states of the two technological acquisition can lead to different accumulation of innovation ability,which leads to different influence.This paper enriched the understanding for competition,which enhanced the explanatory power of the theory of replicator dynamics in emerging market countries and provided advice for the emerging market countries.
