Analysis on Innovation Efficiency of High-tech Industries in the Three Coastal Economic Zones in Eastern China

Abstract

The high-tech industry is an important force in promoting the upgrading of traditional industries and the transformation of economic growth mode. Its technological innovation directly affects the innovation efficiency and economic development level of the region. The three major economic zones of Bohai Rim, Yangtze River Delta, and Pan Pearl River Delta are the most active areas for China's economic development and independent innovation, with a level of technological development far exceeding the average level of China, becoming the three growth poles driving China's economic growth. This article first uses the three-stage DEA Windows method to measure the innovation efficiency of high-tech industries in China's Yangtze River Delta, Pan Pearl River Delta, and Bohai Rim economic zones from 2016 to 2022, and considers the dynamic evolution characteristics of innovation efficiency in each region over time. Secondly, the impact of environmental variables on the redundancy of input variables in high-tech industries in the three major economic zones was studied. Finally, the differences of innovation efficiency values among the three major economic zones were examined. Research has found that after controlling for environmental factors and random errors, the overall innovation efficiency values of the three major regions have not reached the forefront of production, and have shown an increasing trend year by year. Low scale efficiency is the main factor affecting the R&D efficiency of the three regions, and further coordinated planning is urgently needed.
