The inhibitory effect of agricultural fiscal expenditure on agricultural green total factor productivity.

The global Malmquist – Luenberger index is expressed as: 3 M L x f + 1 , y f + 1 , b f + 1 , x f , y f , b f = E g x f + 1 , y f + 1 , b f + 1 E g x f , y f , b f = E f + 1 x f + 1 , y f + 1 , b f + 1 E f x f , y f , b f × E g x f + 1 , y f + 1 , b f + 1 E f + 1 x f + 1 , y f + 1 , b f + 1 × E f x f , y f , b f E g x f , y f , b f = T E C × T C Among them, when the ML value is greater than 1, it indicates that the AGTFP has an increasing trend from period f to period f + 1; when the ML value is less than 1, it indicates that the AGTFP has a decreasing trend from period f to period f + 1, and the efficiency has decreased.
