They were regarded as exclusive luxuries only available to nobles in ancient times. Luxurious jewelry and jade represented by diamonds have entered the homes of ordinary people since the 1980s as a result of the development of the national economy and the growth of people's income after the continuous implementation of China's reform and opening up. The past studies by Chinese researchers on the diamond industry paid more attention to consumption, processing technology, policy support, and marketing and seldom identified problems in the development of the diamond industry from the perspective of industrial development. Little literature deals with the future demand and development prospects of the diamond industry from the perspective of industry clusters. Moreover, the collaborative innovation activities within industry clusters cannot thrive without financial support. While academia has made some research achievements in this area, a study in depth on the current status and the improvement strategies about the financial efficiency for collaborative innovation by industry clusters has not been conducted yet.Based on a review of the related literatures and theories about the collaborative innovation by industry clusters and financial support, this study conducts empirical analysis on listed companies of the lab-growth diamond industry cluster in Henan, China, with the DEA model that measures the relative efficiency of input, showing that the efficiency of the sample cluster companies has kept improving in general from 2017 to 2021, and the level of collaborative innovation in the cluster was also increasing. However, there is a large room for improvement in terms of the absolute value of efficiency. A typical example is their pure technical efficiency fell behind the improvement in the scale of efficiency. Accordingly, the dissertation proposes appropriate measures and recommendations aimed at accelerating the improvement of financial service system, which is of practical significance for facilitating the dual progress and development of both the industry clusters and the financial sector. The financial needs of industry clusters are different from those of individual enterprise. To promote effective collaborative innovation in industry clusters, it is necessary to provide innovative and targeted financial service products and enhance the quality of financial services for collaborative innovation in industry clusters with various development stages and development focuses.95 pagesengIN COPYRIGHT- This Rights Statement can be used for an Item that is in copyright.
