such as intelligent manufacturing, e-commerce platform, Internet
finance, and online retail. Based on the above concepts, we define the
statistical standards for digital economy, mainly involving 11
departments, 32 categories, and 188 subcategories.
(II) Characteristics of digital economy
Metcalfe's Law, Moore's Law and Davidow's Law are the three
internationally recognized laws on digital economy, and are constantly
improving. Under this premise, the following five basic understandings or
characteristics can be refined: the construction of information infrastructure
such as the Internet is a necessary support for digital economy development;
convenience and publicity are important characteristics of the rapid
development of digital economy; inclusiveness is the fundamental attribute of
digital economy development; accelerating industrial integration is the path
of digital economy development; promoting the construction of a modern
economic system is one of the purposes of digital economy development.

2. Methodology
At present, National Bureau of Statistics has not yet clarified the statistical
standards of digital economy, nor has it established the statistical reporting
system for digital economy. All municipal statistical departments are in the
stage of exploring and discussing. In order to reflect the digital economy
development in Qingdao, we tried to establish the digital economic index
system and conducted trial evaluation.
(I) Construction and data source of the evaluation index system for digital
economy development
According to the development characteristics of digital economy, we
select the following digital economy evaluation indexes by combining
with the characteristics and rules of Qingdao's digital economy
development:
1. Digital infrastructure: fixed Internet penetration, mobile Internet
penetration, number of mobile phone base stations, number of 4G
base stations, MAN outlet bandwidth, average speed of fixed
broadband ports, and optical cable length per square kilometer.
2. Digital industrialization: the proportion of new generation
information technology to industrial output; the proportion of
information transmission, software and information technology
service industry to GDP; internal expenses in R&D expenditures for
computers, communications and other electronic equipment
manufacturing industries, and software business income.
3. Industrial digitalization: the index for the integration and
development of industrialization and informatization, the growth rate
of transaction volume via e-commerce platform, the proportion of
