Innovation Efficiency of Chinese Light and Engineering Industry Based on DEA-Malmquist Index Model

Abstract

Scientific and technical innovation is essential for the continuous growth and advancement of the lighting industry. In this study, we utilized the DEA-Malmquist index method to evaluate the innovation input-output efficiency of listed companies in China’s lighting industry from 2015 to 2022. The findings reveal a positive trend in technological innovation within the industry, characterized by increased technological progress and the scale effect. This trend demonstrates the industry’s ability to adapt to market demands and leverage new technologies, contributing to its overall growth and competitiveness. The industry’s emphasis on research and development investment and the introduction of innovative products and processes play significant roles in fostering this positive trajectory. Furthermore, the scale effect observed highlights the benefits of scaling up operations to achieve efficiency and productivity gains. However, to fully capitalize on technological advancements and scale benefits, companies need to strengthen their management practices. Ultimately, the success of the Chinese lighting industry serves as a source of inspiration for other countries and industries, emphasizing the importance of prioritizing research and development, embracing new technologies, scaling up operations, and improving management practices to drive innovation and enhance competitiveness.
