Comparative Analysis of Input-Output Indicator System Method and DEA Method for Measuring R&D Project Input and Output: An Empirical Study Based on Telecommunication Operators

Measuring R&D efficiency is crucial for enterprises to maintain innovation capabilities and optimize resource allocation in an increasingly competitive market. Effective analysis of R&D input-output not only helps companies identify the effectiveness of resource utilization but also provides a scientific basis for strategic decision-making, thereby promoting technological advancement and economic growth. This paper aims to explore the efficiency evaluation of R&D projects by innovatively combining the input-output indicator system method and Data Envelopment Analysis (DEA) method to balance subjective bias and objective analysis while addressing strategic needs.
