“…Research on technological innovation efficiency (TIE) has always been a hot topic at home and abroad. To date, a large number of studies have focused on different aspects, methods, and perspectives:- Some scholars have studied the TIE among different high-tech industries from the perspective of industry differences [13,14,15], while many others study the TIE of HTI from the perspective of regional differences [16] or compare the TIE of HTI at a provincial level in China [17,18], or focus on a particular province or city [19,20,21,22]. In recent years, however, scholars have paid more attention to the development of regional economies, research on the TIE of HTI in a certain economic zone has increased than ever before, especially for the Yangtze River economic belt and the Silk Road Economic Belt, and research on the TIE of regional HTI has increased [23,24,25].
