The study analyzed the productivity of China's high-tech industry from 2000 to 2014. They found that productivity growth rates first increased, then declined, and stabilized in recent years. The eastern, central, and western regions of China had different productivity growth rates. Factors like technical progress, scale efficiency, industrial clustering, export trade, and human capital positively influenced productivity. However, technical efficiency had a negative impact. R&D investment and technology introduction also had positive effects, but were not significant.
