Abstract

This study identifies the complementarity or substitutability among apple production technology bundles. To identify the production technology bundle relationships, this paper focuses on the 8 most commonly used technology groups, including a high density plant, normal density plant, M9, M26, more than 70% adoption ratio of a medium-maturing variety, the adoption of a new variety, artificial pollination, and low-temperature storage. The results show that M9 has a complementary relationship with a high density plant, yet a substitute relationship with a normal density plant. Meanwhile, M26 has a complementary relationship with both a high and normal density plant. No substitute relationship is found between M9 and M26, yet a complementary relationship is identified between the adoption of artificial pollination and low-temperature storage and M9 or M26.
