20 10 joined Shandong university and gave lectures in simple terms, which was deeply loved by students and promoted the frontier research of parallel import theory.
Firstly, the influence of parallel imports on manufacturers' innovation activities is strictly demonstrated in theory for the first time. The research shows that the influence of parallel import on manufacturers' innovation behavior depends on the following factors: the type of innovation activities, the form and degree of enterprise competition (price competition or output competition), the number of manufacturers and/or retailers, the legal regulation and transportation cost of parallel import, the type of parallel imported products (new products or original products) and so on. Secondly, it is proved for the first time that under competitive conditions, production enterprises may use parallel imports to increase market share, thus improving enterprise profits. Thirdly, the influence of parallel import on social welfare is strictly demonstrated, which proves that parallel import may not only improve global welfare, but also reduce global welfare.
In view of the universality of parallel import phenomenon and its important influence on the economies of various countries, my research has strong practical significance. Moreover, because the research on parallel imports needs to involve many players at different levels, such as countries, manufacturers and retailers, and because of the hidden characteristics of parallel imports, it is difficult for people to get accurate statistics on the total amount of parallel imports, so the research is difficult and there are different opinions. My research in this field not only provides a strong judgment basis for people's intuitive argument, but also provides some rigorous theoretical analysis frameworks for future research in this field, so it has strong theoretical significance.
Frontier Research on Technology Authorization and Technology Transfer
First of all, combining technology transfer with enterprise merger and acquisition, this paper not only analyzes the motivation of enterprise technology authorization from the micro perspective of technology-owned enterprises pursuing profits, but also compares the advantages and disadvantages of enterprise merger and acquisition with technology authorization from the macro perspective of maximizing social welfare.
Secondly, when studying the optimal contract of enterprise technology authorization, we comprehensively consider three types of technological innovation (technological innovation of reducing cost, technological innovation of developing new products and technological innovation of improving product quality), and bring durable goods into our analysis framework to analyze the optimal contract of enterprise technology authorization. Finally, the selection of old and new technologies in enterprise technology authorization is strictly verified.
Research on Innovation of Enterprise Location and Industrial Agglomeration
Combined with the theory of spatial competition, this paper explains the phenomenon of industrial agglomeration and seeks the equilibrium of competition. Under the assumption that each enterprise has multiple stores and there is mixed competition between state-owned enterprises and private enterprises, I analyzed the optimal location of enterprise stores. The research conclusion shows that, firstly, no matter how many stores owned by state-owned enterprises, the stores of private enterprises will present agglomeration phenomenon. Second, if the state-owned enterprise has only one store, the stores of the state-owned enterprise and the private enterprise will be unevenly distributed, but if the state-owned enterprise has two stores, the stores of the state-owned enterprise and the private enterprise will be unevenly distributed. 1.2007 was listed in the "New Century Excellent Talents Support Plan" of the Ministry of Education;
