中文摘要: |
基于2011—2020年中国30个省(市、自治区)的大口径统计数据,先利用Super SBM模型测度各地的工业企业创新效率,再利用灰色关联模型,分别计算电信产业和邮政产业与工业企业创新效率的关联系数。结果发现:2011—2020年各地工业企业创新效率值基本呈现出稳定的状态,效率值呈现出明显的东中西部空间分异情况,且东部的优势非常明显。邮政业的灰色关联系数值明显高于电信业,东中西部的灰色关联系数虽没有显现出太大的差别,但仍然可以看到,关联系数与经济发达程度成正比。因此,我国接下来不仅需要大力发展信息通信、移动物联网技术与产业,还要推动区域协调发展,优化省域通信技术与新经济地理的耦合。 |
英文摘要: |
Based on the large diameter statistical data of 30 provinces in China from 2011 to 2020, the Super SBM model is used to measure the innovation efficiency of industrial enterprises in each province, and then the grey correlation model is used to calculate the correlation coefficient between the telecommunications industry and the postal industry and the efficiency value respectively. The results show that from 2011 to 2020, the innovation efficiency value of industrial enterprises in various provinces basically presents a stable state, and the efficiency value shows obvious spatial differentiation in the eastern, central and western regions, and the east has an obvious advantage. The gray correlation coefficient of the postal industry is significantly higher than that of the telecommunications industry. Although the gray correlation coefficient of the eastern, central and western regions does not show much difference, it can still be seen that the correlation coefficient is proportional to the degree of economic development. Therefore, China should not only vigorously develop Information Communication and Mobile Internet of Things technology and industry, but also promote regional coordinated development and optimize the coupling of provincial communication technology and new economic geography. |
