摘      要：This paper investigates the impact of direct and indirect R and D on the productivity growth of 30 French industries during the period 1978-92. The main aim of this paper is to assess the appropriateness of the Yale Technology Concordance (YTC) as a proxy for indirect R and D flows. The effect on productivity growth of the Yale proxy is compared with the traditional proxy based on goods input-output flows, and assess their suitability for different groups of industries. Results indicate that the indirect YTC proxy performs slighly better than the traditional proxy, as a result of superior performace in the high-tech and service sectors in particular.
