Therefore, this study infers the strategic intention behind firms’ R&D from the following three different types of data. The first data source is surveys conducted by industry associations and research organizations. Laser diodes are classified as optoelectronics in the area which light (optics) and electronics merge. Regarding the trends in optoelectronics, the Optoelectronics and Industry and Technology Development Association (OITDA) in Japan has investigated the trends of firms’ production and technological development. Moreover, in the United States, the Japan Technology Evaluation Center (JTEC) sponsored by the National Science Foundation (NSF) and the Defense Advanced Research Projects Agency (DARPA) provided comprehensive reports on the competitiveness of optoelectronics in Japan and the United States. One of the advantages of these surveys lies in collecting data such as the output of each device classified as optoelectronics for each firm. Optoelectronic devices are classified into various types depending on their technological specifications. As will be described later, laser diodes are also classified into many types depending on their wavelength and structure. With these surveys, it is possible to gather data on production with finely categorized levels. However, it must be noted that the survey of industrial association and governmental research organizations may have bias to overestimate the presence of laser diodes, because it might be used to attract the government’s attention to support the industry.

N2 - This study uses various kinds of data to perform longitudinal analysis. Since these data shed light on an aspect of entangled complex social phenomena respectively, it is important to critically review each data source: how the data are collected, embedded biases in the data, data collection methods, and how the data are used in this study.
