Research About Mechanism And Path Of Knowledge Spillover

Knowledge spillover is an externality, which means acceptor of knowledge don't compensate supplier during application of acquired knowledge consciously or unconsciously and amalgamation of other's and own knowledge to tap new knowledge, thus supplier don't acquire all benefit of creating knowledge or compensation less than cost of creating knowledge, the knowledge be acquired by this way and the process of acquiring the knowledge are named knowledge spillover. Romer introduced knowledge spillover into economy theory and made it become an important concept of endogeneose economy growth theory. However, what is essence of knowledge spillover, why and how it produces, these issues don't research deeply and cognitions disagree. The dissertation gives in-depth discussion and not only there is an important science value to deepen new growth thoery and abundant knowledge economy but also there is reality significance to utilize effectively knowledge in economic activity.The paper hackles correlative documents near half century from Mac.Dougall advanced notion of knowledge spillover in 1960, then, analyzes meaning, class, measurement and demonstration of knowledge spillover reached. The paper also agues correlative concept and analyzes character, category, subject, function, periodicity, cause, base and microcosmic influence of knowledge spillover. These shape a basic frame of theory of knowledge spillover.The paper analyzes dynamic mechanism of knowledge spillover from view of dynamics, which indicate a way of linkage of all kinds of factors during corporation absorb outside knowledge. In this mechanism, corporation is carrier whose effect genes interacts and inter-restricts. Genes include cognitive distance, absorption capability, technology gap, space distance and culture distance. Their function leaves each other that cognitive distance is startup, absorption capability is engine, and technology gap is drawer, space distance is roll booster, and culture distance is lubricant. The paper analyzes cognitive distance by topology, verifies absorption capability by region GDP, analyzes technology gap by model of technology gap, analyzes space distance by R&D data of overseas, analyzes culture distance by Hofstede theory for how to affect knowdge spillover.The paper gives a analogy of thermodynamics analyzing the ways of knowledge spillover by different carrier from conduct, convection and radiation three ways. Acquiring spillover through specific carrier such as machine, equipment and erecting manufacture etc calls conduct way, through non-specific carrier such as commodity calls convection way, through learning-by-dong and R&D calls radiation way. The paper analyzes how to acquire knowledge spilloverthrough the three ways in virtue of SPSS software and make use of China Statistics Yearbook and Cob-Douglsa function, moreover, give demonstration analysis and criterion analysis.On the basis of analysis above, the paper advanced how to make decisions to accelerate knowledge spillover and compensate expense of supplier because of knowledge spillover from three aspects, that is, decision optimizing environments of knowledge spillover, decision perfecting mechanism of knowledge spiUover and aim at different ways has different measures.
