Abstract

Abstract:

Taking the data of 60 counties in Zhejiang Province from 2015 to 2019, this paper empirically analyzed the effects of agricultural science and technology investments on agricultural economic growth by using panel data model. The results showed that by controlling other input variables, on the whole, financial investment in agricultural science and technology was positively correlated with agricultural economic growth, and its positive effect in underdeveloped south-west counties was significantly higher than that in developed north-east counties. The input of agricultural scientific and technological personnel only showed a positive effect on north-east counties, but not on south-west counties. The effects of other control variables on agricultural economic growth also showed some differences, in which the total power of agricultural machinery did not show a positive effect. Therefore, in the “double strong” action of strengthening agriculture through science and technology and machinery in the coming period, Zhejiang should continue to increase financial investment in agricultural science and technology and tilt to the south-west counties of Zhejiang, and actively optimize the allocation of agricultural science and technology personnel. In the south-west counties of Zhejiang Province, we should focus on optimizing the allocation of agricultural science and technology personnel to adapt to agricultural production. In the north-east counties of Zhejiang Province, we should focus on strengthening the introduction and training of agricultural science and technology personnel to build a strong agricultural science and technology team, Furthermore, the renewal of old agricultural machinery and equipment, as well as the development and promotion of new practical agricultural machinery and equipment should also be accelerated.

Key words: investment in agricultural science and technology, agricultural economic growth, panel data model, regional difference, strengthening agriculture through science and technology and machinery
