3. Survey Characteristics
- The questionnaire was initially developed in English and then translated into Chinese by the local partners from the Institute of Applied Ecology (Chinese Academy of Sciences, Shenyang, China). For a pretest, the questionnaire was discussed with some potential interviewees and slightly revised based on their feedback and comments. To verify the translation, the Chinese questionnaire was re-translated again into German by a native Chinese Speaker, who is not involved in the project.
- The distribution of the 120 questionnaires was carried out via email and through on-site visits including direct interviews. Additionally, the distribution was supported by the local government. All of the 120 sent out questionnaires were returned; most were sent back via email (47) or were collected from the local governments (40), while 22 were collected on site.
- Finally, the collected responses were aggregated and documented. Of the 120 questionnaires that were sent out, 11 were returned incomplete, leading to a sample of 109 complete questionnaires. The sample focused on medium to large sized companies. Most are located in Liaoning Province (typical industrial zone located in northeastern China) with 102 returned questionnaires; seven questionnaires were collected from Jiangsu Province and Gansu Province. Fifty-six percent of the companies involved in the survey have more than 250 but less than 1000 employees, 22% employ between 1000 and 2500 people, 6% fewer than 5000 but more than 2500 people and 16% more than 5000 people. The main branches represented in the sample are machine and plant engineering (24%), automotive (22%), information and communication technologies (17%), electronics (15%) and aerospace (12%). Participants in the survey are mainly male (73.4%) and work in the two engineering domains: development (34%) and manufacturing (66%). The sample choice (regional focus, focus on medium and large size companies) was based on the experience and networks of our Chinese partners to increase the probability for good availability and relevance of partners.
