According to the "Guide to the Second Half of 2017 Global Expenditures" released by IDC, China's IoT spending is projected to reach $291.22 billion by 2021. Over the next five years, the country’s IoT market is expected to grow at an average annual rate of 11.9%. As more industries embrace smart technologies, the clustering effect of IoT will become increasingly evident in areas like smart cities, intelligent transportation, energy efficiency, and retail.
The report highlights that China’s IoT spending will account for 25.6% of global expenditures by 2021. This growth is driven by government support, improved standards, and rising demand for smart infrastructure and enterprise digital transformation. With the development of 5G, NB-IoT, and eMTC, IoT applications are expanding rapidly across sectors.
In 2017, the Ministry of Industry and Information Technology launched the "13th Five-Year Plan for IoT," setting clear goals for industry development. Major telecom operators also rolled out subsidies for IoT, promoting the adoption of NB-IoT technology. As these technologies mature, IoT platforms and terminals are expected to see sustained growth.
Looking ahead, the industrial impact of IoT will be more visible in sectors such as public safety, logistics, and environmental monitoring. The market potential of IoT is no longer limited to IT or telecommunications but extends into broader economic and social domains.
Smart city platforms are enabling new business models, such as BOT, EMC, and public service procurement, which help drive urban innovation. As IoT networks expand, applications in smart transportation, infrastructure management, and energy conservation will become more widespread.
By 2017, all three major telecom operators had commercialized NB-IoT networks, with base station numbers far exceeding the initial targets. This coverage has accelerated IoT deployment in smart cities, logistics, and agriculture, showcasing its growing commercial value.
As technologies like eMTC, LoRa, and 4G+ continue to evolve, more communication solutions will emerge to meet diverse IoT needs. In logistics and retail, IoT is transforming supply chains and delivery systems, with companies investing more in data integration and analysis to unlock greater value from their operations.
Euroblock, short for "European-style terminal block"; is a combination of a low-voltage disconnect (or pluggable) connector and terminal block commonly used for microphones and line-level audio signals , and for control signals such as RS-232 or RS-485. It is also known as the Phoenix connector and comes from a German Phoenix Electric Company, which was established in 1981 in Harrisburg, Pennsylvania, USA. Also known as "Plug-in Terminal Blocks" or "Two-Piece Terminal Blocks".
