*3.1. Variable Measurement*

A survey of the 512 industry-academic linkage projects was implemented from July 2018 to December 2018, which collected 467 answers from relative technical managers of firms in 17 high-tech industries in China. 398 effective questionnaires were obtained, with a recovery rate of 77.7%. The Cronbach α internal consistency coefficient values of the four main variables are all over 0.8, indicating that the four indicators have high internal consistency, and the questionnaire design meets the reliability requirements (See Table 2 for details).


**Table 2.** Result of variables measurement.

Descriptive statistical findings that (1) the overall level of knowledge exploratory learning ability in industry has reached a high level, but there are still significant differences between individuals. Meanwhile, the level of knowledge sharing ability is generally quite low; (2) although the level of the useful knowledge generation ability in academia is relatively high, the knowledge interpretation ability and knowledge dissemination ability are still very low; (3) compared with academic incentive policy and environmental incentive policy, industrial incentive policy has not been highly recognized; (4) the overall performance of collaborative innovation projects is low, and the differences between individuals are quite large.
