Evaluation of the high-quality development of China's media industry

Accelerating the in-depth integration of media to achieve high-quality development in the media industry has become important for China's cultural media. We built a high-quality development index system for China's media sector and used financial data from A-share media industry listed companies from 2017 to 2020 to measure the high-quality development index of China's media business using the Global Malmquist-Luenberger production function method with the framework of the SBM model degree. We used the generalised method of moments model and the singlethreshold model to estimate the threshold value of the media convergence degree and its factor distortions. Deep media integration can promote high-quality development in the media sector. However, insufficient and unbalanced development of media integration is the main hindrance to China's high-quality development of its media.
