“…In terms of OI classification, three significant schools of thought have been formed based on different perspectives: process [5,6], strategy [7], and characteristics [8]. Related studies mainly focus on closed innovation [9,10], dual innovation [11,12], human resources [13,14], and firm performance [15,16], and use empirical analysis [12], case studies [11], and simulations [10] to analyze the interplay between different factors. In terms of research objects, there are three primary levels: first, the macro level in the region, such as countries [17] and industries [18]; second, the specific middle level, such as enterprises [11,19] and universities [12,20]; and third, the micro level, such as projects [21].…”
