Abstract: In recent years,the major developed countries all over the world have launched many manufacturing strategies,in order to seize the commanding heights of the future competition.In a critical period of economic transformation and upgrading,only by accelerating the pace of industrial upgrading and enhancing the core competitiveness of the industry can China be able to remain invincible in the increasingly fierce international competition.The correct understanding of the factors,which is affecting the industrial upgrading,is of great significance in the process of making scientific and effective industrial upgrading strategies.To explore the combinative effects of several factors on industrial upgrading,we collected data samples from 22 countries and used the qualitative comparative analysis method(QCA) to analyze factors including brand advantage,technological innovation level,human capital,openness to the outside world and intellectual property system.The result shows that:①The comprehensive investment in four aspects including technological innovation,human capital,openness to the outside world and intellectual property system can effectively promote the process of industrial upgrading.②On the premise of weaker technological innovation and weaker human capital,the combination of measures,such as cultivating brand advantage,enhancing the degree of openness to the outside world and strengthening the construction of intellectual property system,has a positive effect on the process of a country's industrial upgrading.③The lower development of technological innovation and intellectual property system will become the constraints of a country's efforts to industrial upgrading.The conclusions indicate that:China should fully invest in these four aspects of scientific and technological innovation,the human capital supply,the openness to the outside world and the intellectual property system,so as to form a policy to make great progress in industrial upgrading.What's more,China should attach great importance to and make efforts to solve the problems restricting scientific and technological innovation Level and the intellectual property system.
