Dynamic Evaluation on High-Quality Development Level in the Manufacturing Industry

Promoting high-quality development of the manufacturing industry is the key to achieving sustainable economic development. The development of the manufacturing industry is affected by a variety of factors, and it is particularly important to reflect on its level of development from multiple perspectives. This paper built an evaluation indicator system for the manufacturing industry's high-quality development using the structural equation model. An improved TOPSIS evaluation model was constructed based on the combined weighting of the level difference maximization method. The time series arithmetic mean operator was introduced to assign weight to time, and the quadratic weighted integration enabled a dynamic evaluation. The level of high-quality development of China's manufacturing industry from 2018 to 2022 was assessed both statically and dynamically. According to the findings, the overall high-quality development of China's manufacturing industry exhibited a trend of first declining and then increasing when the current status was only element taken into account. Regionally, there was a sequential decline from the east to the central part, followed by the western and northeastern regions. When focusing solely on the degree of growth, it was higher in the northeast and lower in the east. However, the regional characteristics declined when both the current status and the degree of growth were considered. Evaluating the high-quality development level of the manufacturing industry can provide references and lessons for promoting regional coordinated and sustainable development of China's manufacturing industry.
