Abstract
This paper clarifies the features of large-scale vegetable farms and related industries in California. Vegetable farming in California is remarkable for its concentration on the large-scale farm. As many of the large-scalefarms are supported by vegetable production and marketing-related companies, there are many related companies in the area. Their business features are various: some are large and others are small; some are subsidiaries and others are invested jointly by large-scale farms. This paper discusses the industrial cluster formed by the large-scale vegetable farms and their related companies.
