their engagement in OWP activities is negligible. Similarly, we refer to all firms engaged in PV as PV
firms. Thus while a firm may normally be referred to as for instance oil & gas or consultancy firm, we
refer to them as PV or OWP firms given that our primary focus is on their activities in these industries.
Since we could not prior to contacting the respondents know whether the firms had ambitions in OWP
or PV, the original sample totalled 243 firms and included a number of firms that responded that they
were not engaged in these industries. The survey with these firms was not continued, and they were
excluded from the sample. Following this exercise, the total sample consisted of 213 firms (155 OWP
and 58 solar PV). 158 firms responded to the survey (108 OWP and 50 solar PV), with a response rate
of 74
% 1. After cleaning up the data by removing responses that did not meet our selection criteria, we
were left with 151 responses (71 %) for our analysis (102 OWP and 49 PV). In spite of a careful sample
selection process there may exist uncertainties with regards to firms that have not been included in
the sample. This may primarily be because it is difficult to know whether firms with primary activity in
other industries are engaged in OWP or PV. As there may be firms that have ambitions in PV and OWP
that we did not have in our original sample, it is difficult to estimate the exact total number of
Norwegian firms with activities in OWP or PV. We do however believe to have sampled a significant
proportion of relevant firms.
Survey respondents were CEOs or managers of OWP or PV activities. For some firms, these were
owners or directors of the company, whereas for other firms respondents were head of divisions
within a larger organisation. The survey was conducted via telephone and each interview lasted
approximately 20 minutes.
The design of the survey involved multiple steps. First, we identified six key areas of interest based on
the perspectives on industry formation and internationalisation discussed in sectio
n 2:Firm characteristics:
We here used different indicators to capture the relative importance of OWP or
PV within the organisation (importance of OWP or PV to the organisation, number of full-time
equivalents dedicated to OWP or PV, share of total turnover from OWP or PW). Further, based on
the importance of related industries discussed in sectio
n 2.2we included questions about primary
sector and experiences that were relevant for activities in OWP or PV. Answers to questions on
primary sectors and experiences from other sectors were aggregated into main sectors. Where
necessary, ambiguous answers were standardised through additional desk research. Additionally,

7 of these firms responded that they had previously delivered products or services to the OWP or PV industries, but that they no longer had
any ambitions to do so. Consequently, these firms were not asked to complete the survey.
