Fig. 1: Theoretical framework for the evolution mechanisms of GTIE–CE.
From: Explaining the changes in the green technology innovation efficiency of construction enterprises

(1) The super-SBM was adopted to measure the GTIE–CE according to resource orchestration theory and eco-innovation theory. (2) The spatial variance function and PVAR model were used to reveal the evolution mechanism of GTIE–CE according to asymmetric innovation theory.
