The Development Effect of Industrial Upgrading and Motive Cause Analysis

Industrial upgrading is one of the major themes in modern economic development. It embodies the evolution trend that industrial frame transforms from the low technique level and the low extra-value state to a higher new technique level and greater extra-value state. The ideas that economic developing rate and benefits come from the industrial frame evolution are the kernel of industrial policies. The traditional economic theories think that the changing in the demand income elasticity and the productivity enhancing are two primary drives of the industrial upgrading. In fact,the demand income elasticity is the result of the market scale expanding while the productive differences among different industries should attribute to the changes of the labor division level. The drives of industrial upgrading should be explained from the angle that knowledge and labor power capitals are integrated to the processes of commercial manufacture in great numbers on the basis of economic entities pursuing the division of labor and the reduction of transaction costs.
