Product Life Cycles and R&D Intensity by Sector (L. Kamran Bilir, 2013)

L. Kamran Bilir (2013),  in an effort to explain how patent law enforcing and product life cycle length affect multinationals’ decision process, created a table (Table below) where the product life cycle length and the R&D Intensity is compared. Normally the product lifecycle is determined by the average retail duration of individual product varieties, however the approach used by Bilir consider the economic durability of an embedded technology. Bilir used the length of time in which a given patent continues to be cited by subsequent patents, considering that if it is still being cited it keeps a certain economic value. Regarding the relationship between the life cycle and the R&D intensity, reasoning would suggest that an industry with a short product cycle length would invest more in R&D in order to be up to date with competition. This R&D intensity and product life cycle length will drive a more complex and dynamic market.  Given the values below, the product life cycle length with Bilir approach and the R&D intensity have a weak correlation (-0.297554). However, its sign is still aligned with the  the inference above; allowing to maintain the initial assumption.

R&D to Production 1991 – 1999 mean (OECD, 2003)

The OECD gathers and analyses information regarding economic growth and international trade among member countries. Since technology is not wide spread across an economy, the study of technology intensity impact on an economy can be challeging. In an effort to contribute to research in this area, the OECD established a classification for the industry (see more). This post presents some of the results used to determine their classification. The following table shows the mean of R&D over production for different industries during the period of 1991 to 1999 for 12 OECD countries. Below the mean for the different levels of Technology Intensity.
