Efficiency Analysis of Scientific and Technological Innovation in Grain Production Based on Improved Grey Incidence Analysis

Analyzing and evaluating the efficiency of scientific technological innovation in grain production is conducive to rational allocation resources, promoting development providing guarantee for security. By refining elements innovation, an evaluation system constructed. Firstly, combining linear programming together with traditional grey synthetic incidence analysis model, a indicators carried out, key secondary indexes affecting outputs are screened by improved model. Secondly, based on DEA-Malmquist index model taking process as research object, achievement transformation divided into pre-production, in-production post-production indicators. The various cities Henan Province from 2010 2019 used analyze each stage production. results show that: (1) type basic ability achievements major influencing outputs, investment resources most important improve outputs. (2) In addition, study reveals that more efficient than stages. And there gaps performance among Province, progress leading factor gap.
