为全面客观分析不同公司治理机制对企业创新的影响,基于Web of Science数据库2000-2019年463篇公司治理视角下企业创新研究文献,运用CiteSpace软件绘制文献时空分布、双期刊叠加、文献共引及聚类、关键词时区等知识图谱,厘清研究分布情况、脉络轨迹及发展前沿。结果表明,文献数量逐年提高且尚未达到峰值,美国、中国为高产国家,该领域研究存在不同学科期刊间的知识流动。研究视角划分为创新决策动态视角、特定股权背景视角、委托代理视角,形成了以所有权结构、董事会职能及高管治理对企业创新影响为基础的研究主题框架,研究热点和前沿随公司治理主体关注重点变化和创新类别细化发生动态演进。最后,针对研究薄弱环节,提出未来研究方向。
Being a developing country, the evaluation of Chinese circular economy should have its particular crite- rion that suits for specific national conditions. With the growth of economy, Chinese environmental loads should be permitted to increase at an appropriate speed. Based on this concept, this paper divides the process of evaluation into two parts which include evaluation of development level and evaluation of development performance. Firstly, this paper sets up a reference system which includes Zaozhuang City of Shandong Province, Jiaozuo City of Henan province, Shizuishan City of Ningxia Hui Autonomous Region and China that is regarded as a region respectively, analyzes the development level of circular economy of coal resource cities based on the evaluation indicator of ecological efficiency, and puts forward the future direction of circular economy of coal resource cities. Secondly, based on C Model of Circular Economy, this paper constructs the measurement model of development perform- ance in which study regions are analyzed in a particular period that is from 2000 to 2020, and evaluates the de- velopment performance of circular economy for study regions according to the relationship of growth multiples between economic scale and environmental loads. We can draw several main conclusions： firstly, the development pathways of all four study regions belong to type I[ which resource efficiency is preferred. Secondly, the com- prehensive energy consumption efficiencies of coal resource cities were left far behind by China＇s average level. Thirdly, the circular economies of all study regions have achieved remarkable progress. Fourthly, the development level of circular economy can be evaluated from two dimensions which consist of horizontal comparison method and vertical comparison method. Fifthly, C model is an appropriate development model that suits for Chinese na- tional conditions and could be selected as an important method to evaluate regional development performance of circular economy.
