A Study On Issue Of Export Diversification And Industry Performance

In this study,we construct the index of export diversification,industry output volatility and performance dispersion.We empirically test how the expert diversification affects industry output volatility and performance dispersion using 2002-2015 multinational enterprises data and trade data,and reach the following conclusions:first,the increasing of export diversification significantly reduced the output volatility of industry,and in the industries with stronger comparative advantage,the greater the degree of trade openness and the higher the competitiveness of the industry,the more obvious the effect of the stabilizing function;second,the increasing of export diversification is conducive to promoting the competition in industry,which effectively reduces the degree of industry performance dispersion and optimizes the allocation of resources.In the industries with comparative advantages,higher capital intensive and the greater the degree of trade openness,the result of optimizing resource allocation is more significant.Moreover,the above conclusions are substantially verified base on different variable selection and construction methods.The research result of this paper provides favorable support for the relationship between export diversification and industry performance at the industry level.
