Differentiation and Convergence of Technological Innovation Efficiency in China’s Equipment Manufacturing Industry

Technological innovation is the core driving force driving China's equipment manufacturing industry to achieve high-quality development. This paper takes China's equipment manufacturing industry as the research object, based on dividing the technological innovation process into two stages: technological research and development and economic transformation, using the super-efficient DEA-SBM model to measure the technological innovation efficiency of China's equipment manufacturing industry from 2011 to 2020, and analyzing in-depth the evolution law of technological innovation efficiency of China's equipment manufacturing industry. The specific conclusions as: Firstly, China's equipment manufacturing industry technology innovation efficiency is low, the low efficiency of technology research and development is the main reason; Secondly, China's equipment manufacturing industry technology innovation efficiency has a large space for improvement. There are 11 provincial administrative regions with equipment manufacturing industry technology innovation efficiency shows "high and low" characteristics, and 13 provincial administrative regions with equipment manufacturing industry technology innovation efficiency that shows "double low" characteristics; Thirdly, the technological innovation efficiency of China's equipment manufacturing industry shows a spatial distribution pattern of "high in the east and low in the west", and the spatial spillover of technological innovation efficiency is not obvious. Based on the conclusions of the study, specific measures to enhance the technological innovation efficiency of China's equipment manufacturing industry and promote the synergistic development of inter-regional technological innovation efficiency are proposed from the aspects of promoting the synergistic enhancement of technological research and development efficiency and economic transformation efficiency and promoting the synergistic development of inter-regional technological innovation efficiency.
