Research on Collaborative Innovation Evaluation of Intelligent Logistics Park
构建了从智能化、协同能力和创新能力三个维度评价智能物流园区协同创新能力的指标体系，用主成分分析和数据包络分析对长江经济带18个园区进行实证，发现投入产出冗余和区域差距问题。
The collaborative innovation capability of intelligent logistics parks plays a crucial role in promoting their development, but still encounters various problems in terms of progress. On the basis of summarizing the evaluation indexes and methods of collaborative innovation capability in logistics systems, this article constructs an evaluation index system from three dimensions of intelligence, collaboration capabilities, and innovation capabilities using the combined principal component analysis and data envelopment analysis (DEA). In this empirical article, 18 intelligent logistics parks in the upper, middle, and lower reaches of the Yangtze River Economic Belt are taken as the research objects to analyze the key factors influencing collaborative innovation of practical intelligent logistics parks. Results show that, on the one hand, the collaborative innovation process of many intelligent logistics parks have redundant inputs and outputs, which leads to failure of realizing DEA effectively; on the other hand, gaps in the collaborative innovation level leads to failure of realizing the overall coordinated development. The level of economic development cannot completely determine the level of collaborative innovation of the intelligent logistics park.
