Research on Total Factor Productivity of High-Tech Parks Based on the Perspective of Technology Field: Taking the Zhongguancun Demonstration Zone as an Example

摘要

In order to clarify the economic growth dynamics of high-tech parks and the method of improving total factor productivity, this paper adds dummy variables to the stochastic frontier model method to consider the difference of total factor productivity among different economies, and combines clustering methods to verify The shortcomings of lower-economy economies and recommendations for science policy. This paper takes the six technical fields of Zhongguancun as the empirical object. The calculation results show that from the time axis, since 2002, the growth rate of total factor productivity in various technical fields of Zhongguancun has declined, but there have been signs of recovery in recent years. From the perspective of domain differences, the level of total factor productivity and the quality of economic development in the field of electronic information are the highest.
