Abstract: By adding technology intensity variable and technology gap variable，this paper extended the technology innovation and growth model in a North-South framework to the industry level and discussed the influences of industrial technology characteristics on innovation effect of intellectual property protection. The results showed that heterogeneity of industrial technology characteristics impacts the innovation effect of intellectual property protection. The high technology-intensive industries are more sensitive to the intellectual property protection and as technology gap narrowed, the incentive effect will gradually highlight. Empirical test by using the data of China's 19 subdivided industries of high technology industry from 1995 to 2011 also supports these conclusions. Different from intellectual property protection system following the rule of “one size fits all” now, we divided the 19 industries into four groups and proposed different intellectual property protection policy based on industrial technology characteristics.
