西安市科技金融发展效率及动态影响研究

Research on the Efficiency and Influence Factors of Sci-tech Finance in Xi'an

摘要:

西安市被列入国家第二批科技创新试点城市之一，研究其科技金融发展效率和影响因素，对加快科技金融高质量发展具有重要意义。在选取典型投入与产出指标基础上，运用超效率DEA模型测度西安市科技金融投入产出效率，并采用VAR模型分析了投入产出系统之间的相互影响关系。实证分析表明，在2000-2018年期间，西安市科技金融效率得到大幅提升，但仍处于规模收益递增阶段，在加大科技金融投入的同时也要把握投入时机和平衡投入资源，发挥资源最大效用。

Abstract:

Xi 'an was listed as one of the second batches of national pilot cities for sci-tech innovation. To study the efficiency and influence factors of sci-tech finance, it had great significance to accelerate the high-quality development of sci-tech finance. Based on selecting typical input-output indexes, the super-efficiency DEA model was used to measure the input-output efficiency of sci-tech finance in Xi 'an. Then, the VAR model was used to analyze the interaction between input-output systems. The empirical analysis shows that the efficiency of sci-tech finance from 2000 to 2018 had been greatly improved in Xi 'an. However, it was still in the stage of increasing returns to scale. While increasing investment in sci-tech finance, it is necessary to grasp the timing and balance the investment to maximize the utility of resources.
