Managerial Ability and R&D Investment: An Empirical Analysis Based on DEA-Tobit Model

DEA is a statistical procedure used to evaluate the relative efficiency of separable entities, termed “decision-making units” (DMUs), where each DMU converts certain inputs into outputs. The methodology can provides an ordinal ranking compared Pareto-efficient frontier, and widely measure require that weights be explicitly set, which more advantageous than conventional measures efficiency. Tobit model dependent variable limited model. Since value measured by truncated discrete distribution between 0 1, effectively avoid problems bias inconsistency in parameter estimation. Based on this, this paper takes Chinese A-share listed companies from 2008 2018 as samples, adopts DEA-Tobit managerial ability, studies impact ability firm innovation investment. It found negatively correlated with R&D Further research shows negative relationship investment significant non-state-owned companies. Transparency accounting information alleviate restraining effect managers input. This study not only enriches literature field input, but also has important enlightenment significance how improve willingness reality further promote behavior.
