The Impact of Multidimensional Proximity on Innovation Spillover:A Life Cycle Perspective
Innovation spillover is an important step to accelerate the realization of high-level sci-tech self-reliance and self-strengthening,and is also a key link in building the new development pattern.The paper divides the innovation life cycle into search period,familiar period,change period,revitalization period,substitution period and silence period.Based on the patent data from 1985 to 2022,using QAP regression analysis method,this paper studies the influence of multidimensional proximity on national innovation spillover in different periods.The results show that:cognitive proximity significantly promotes innovation spillover during innovation life cycle,indicating that cognitive difference was the basis of innovation spillover and significantly affected the spillover demand and cost.Technology,geography and relationship proximity significantly promote innovation spillover in the first five periods,indicating that technology,geography and relationship proximity increase spillover demand and reduce spillover cost.Due to spatial lock-in and crowding effects,geographical proximity significantly inhibits innovation spillover during the silent period.Due to intellectual property protection and institutional lock-in,social proximity significantly inhibits innovation spillover during in the familiar period,change period,the revitalization period and the substitution period.
