Based on resource dependence theory and social exchange theory,this paper first builds a theoretical model of “resource dependence——trust,relationship commitment——information sharing”,then selectes the company as the research survey from the “company + farmer household” organization model,and collected 202 samples to analyze the relationship among resource dependence,trust,relationship commitment and information sharing by using structural equation model.The result shows that company’s trust has a significant positive impact on firms` relationship commitment and information sharing between company and farmers.The relationship commitment has a significant positive impact on information sharing.Resource dependence has a significant positive impact on trust and relationship commitment,which does not have a directly significant impact on information sharing.Therefore,this paper suggests that managers of agricultural enterprises may use the investment of complementary assets to increase the dependence of companies on the farmers in order that a high level of trust and relationship commitment with farmers can be established,which will promote farmer to be more willing to share the production information with company so that enterprises can effectively monitor production process of agricultural products and improve the quality and safety of agricultural products.
