Evolutionary decision‐making behaviour among the government, leading enterprises and farmers: Based on the improvement of phaeozem quality in Northeast China

The improvement of phaeozem quality in Northeast China is crucial to China's food security. This study incorporated government, leading enterprises and farmers into an evolutionary game model to explore the ideal state among the government, leading enterprises and farmers with the improvement of the phaeozem quality in Northeast China, thereby contributing to food security. The study includes the government, leading enterprises and farmers in an evolutionary game model to explore game relationship and evolution paths of decision‐making among the three stakeholders, and obtains the conditions for the three parties to evolve to the ideal state by analysing and combining with the actual data. The evolutionary process of the decision‐making behaviour of the three stakeholders to an ideal state is affected by many factors, and the value ranges of the different factors have different impacts on the convergence speed of the three stakeholders to an ideal state; when certain conditions are met, the decision‐making behaviours of the three stakeholders can evolve to an ideal state, which aims to provide beneficial suggestions for the government to supervise the quality of phaeozem, leading enterprises to control green agricultural products and farmers to apply organic fertilizer.
