As the proportion of non-local farmers among suburban vegetable growers continues to increase and the differentiation among farmers has intensified,it is of great significance to identify the characteristics of vegetable production by local and non-local farmers in order to improve the capacity of vegetable emergency supply in cities.Based on the survey data from 203 households in Beijing,analysed the production characteristics of local and non-local farmers.The results show that the heterogeneity of the vegetable production of local and non-local farmers is evident and manifests itself in three aspects.First,factor inputs,mainly labor and land inputs rather than capital inputs.Second,technology promotion and adoption,mainly technology subsidies,technology training and the adoption of quality and safety-oriented technologies,rather than the adoption of yield-enhancing and environmentally friendly technologies.Third,cost benefits,mainly employment costs,rent costs and costs returns.The technology promotion,adoption and cost benefits of local farmers are higher than those of non-local farmers,while the factor inputs of non-local farmers are significantly higher than those of local farmers.This indicates that non-local farmers'facility vegetable production relies mainly on factor inputs rather than technology adoption,resulting in high costs and low benefits.Therefore,countermeasures were proposed:emphasize the cultivation of New Agricultural Business Entities,strengthen financial support,and accelerate the popularization and application of new technologies,so as to break the constraints of facility vegetable production for both local and non-local farmers,and promote the overall improvement of production capacity.
