中国城市数字鸿沟时空分异及其影响因素.

The imbalance in the acquisition and use of information and communication technol‐ ogies(ICTs) in cities has become a key problem restricting the construction of Digital China. Therefore, analyzing the differences and influencing factors of urban informatization level has become an important content of narrowing the digital divide. Using the information and commu‐ nication technology development index(IDI) defined by the International Telecommunication Union, this paper uses the location entropy method to measure the difference degree of informati‐ zation level of 275 cities in China since 2005, and then uses the spatial analysis and econometric methods to analyze their spatio-temporal differentiation pattern and influencing factors. It is found that:1)China's ICT Development Index Location Quotient(IDILQ)is still at a low level. Al‐ though the digital divide between regions tends to converge, there are still great differences among the east, middle and west regions. 2)From the perspective of temporal and spatial pat‐ tern, the IDILQ "H-H" agglomeration area has always been located in the Yangtze River Delta and Pearl River Delta along the eastern coast, and the "L-L" agglomeration area has transferred from the western region to the central region. 3)Cities with high IDILQ have a "polarization ef‐ fect" on surrounding cities. However, the higher the proportion of young population, the higher the level of urbanization and the larger the proportion of employees in the information technolo‐ gy industry, the more conducive it is to improve the IDILQ and narrow the digital divide. In the transformation of digital revolution, we should guard against the adverse impact of information‐ ization on the construction of shrinking cities and aging cities. [ABSTRACT FROM AUTHOR]
