Analysis on Scientific and Technological Innovation of Grain Production in Henan Province Based on SD-GM Approach

Relying on scientific and technological progress to improve the yield per unit area is the main way to achieve sustained growth of grain output. From the perspective of scientific and technological innovation, taking the grain production process as the research object, and based on the relevant data of Henan Province from 2010 to 2019, a system model of scientific and technological innovation in grain production is constructed. Firstly, the internal mechanism of grain production scientific and technological innovation is explored, and the feedback loop of grain production scientific and technological innovation is then constructed. Secondly, the combination of system dynamics and grey system theory is implemented to construct the table function and logic function, and the model of grain production scientific and technological innovation system is constructed. To prove the stability and feasibility of the model through tests, the medium and long-term simulation and prediction of grain production scientific and technological innovation system in Henan Province are carried out. Thirdly, in order to explore the impact of feasible policy schemes on grain production, seven policy plans are designed to simulate grain production policy scenarios from the perspective of scientific and technological innovation. Finally, from the perspective of the composition of scientific and technological innovation system in Henan Province, this study puts forward countermeasures and suggestions for the implementation of the strategy of “storing grain in technology” in Henan Province.
