Abstract Considering a firm’s citing patents as technology input and its authorized patents as technology output, this paper aims to measure the technological interactions among Apple ecosystems. First, it conceptualizes a theoretical framework including the direct-citation coefficient, co-citation efficient, and coupling coefficient. Then, it estimates the technology influence coefficients and technology sensitivity coefficients. Further, it evaluates the comprehensive technology capabilities of 11 firms in Apple ecosystem, based on the patentee citation networks data from 1998 to 2014. Results show that Intel and AMD are technology leaders in the mobile intelligent terminals industry, Apple has a strong but gradually waning technology influence, and Samsung has a high and rapidly improving technology sensitivity. This method can be applied in other analyses such as industrial technology competence analysis and technology spillover and knowledge flow analysis among firms or regions.
