The Relationship Among The Diversification Of Dominant Enterprises,Market Structure And International Competitiveness Of Industry

At present,the competitive landscape of global manufacturing industry has changed,and countries are returning to manufacturing.Manufacturing industry has once again become the frontier of competition among countries,and it is imperative to improve the international competitiveness of the manufacturing industry.During the "new normal" period of China's economy,the manufacturing industry needs to complete transformation and upgrading to enhance its international competitiveness and occupy a place in global competition.With the advancement of transformation and upgrading of China's industry,academia gradually pay attention to the market of "subjective initiative" role is not smaller than the government to promote the industry global competitiveness.Namely,the enterprises behavior is no longer passively accept the influence of industry environment,but can also affect the performance of the industry.Under the special situation in China,the manufacturing enterprise performance very different from western's "refocusing strategy",and show different degree of diversification.Different degree of diversification helps manufacturing enterprises have advantages in resource acquisition,scale economies and market power;and the enterprises will receive different levels of competitive advantage,thus affect industrial international competitiveness.This paper focuses on the diversification of the dominant enterprises is the key factors that affect the international competitiveness of the industry.Two core issues were discussed:(1)what kind of impact will the degree of diversification have in the industry international competitiveness advantage?(2)if the impact exists,how will the diversification of the dominant manufacturing enterprise affect the international competitiveness of the industry?Based on the new industrial organization theory,this paper built theoretical framework,and put forward relevant proposition and inference,and used the quantitative method of the statistical analysis to test hypothesis.On the basis of the theory of "use micro data to the macro forecast",this paper choose the listed companies of electron and communication equipment manufacturing industry,and biological medicine manufacturing as the researchobject,and collected the secondary data to achieve empirical research.The following are the main conclusions:(1)there is a significant U type nonlinear relationship between the degree of diversification and the industry.That means that moderate diversity of advantage enterprises will form the strongest industry international competitiveness,simplified operation or excessive diversification is damaging to the industrial international competitiveness,industrial comparative advantage and competitive advantage are diminished.(2)manufacturing enterprise diversification influence the industry international competitiveness through market concentration.At the same time,the enterprise diversification has a strong u-shaped nonlinear relationship with industry competitiveness.It means that when the manufacturing enterprises are moderate diversity of,the industry market concentration is highest,the industrial structure achieve the best condition;and simplified operation or excessive increase the concentration of diversity,and industry structure can't optimize,industry competitions are more invalid.This paper constructs the relationship between the degree of diversification and the international competitiveness of the industry for the first time,realizes the dialogue between the micro and the macro.In this paper,we find that market concentration is a bridge between micro and macro,which transfers the effect of independent variables' micro behavior to the medium scale's industrial performance,and finally realizes the path of micro to macro.In this paper,we construct the multi-level model of the influence of "low level variables on high level variables",and use the method of "from the micro point of view" to construct the influence path of the diversification degree,market concentration degree and industrial international competitiveness of the superior enterprises.In the theoretical framework,the micro enterprise diversification data is treated as macro data for regression analysis,and finally the conclusion of this paper is drawn.
