"Tongling is a typical representative of old industrial cities, rich in industrial big data resources, and there is an urgent need to dig deeper into the value behind the data to promote the upgrading of old industrial cities." Recently, in Tongling City Tongdu Innovation town, Anhui Yangtze River Industrial Big Data Technology Company product director Zhou Zhongke said.

On March 28, 2019, Anhui Changjiang Industrial Big Data Technology Co., Ltd. was established. With the "industrial Internet" and "industrial data" as the core, the company is committed to promoting the "Tongling Industrial brain" deep cultivation and localization of results, contributing Tongling wisdom and experience to the industrial big data industry ecology of the Yangtze River Delta Economic Belt and the transformation and upgrading of traditional industrial cities across the country.

Since its establishment, the company's "Yangtze Cloud Industrial Internet Platform" has 11 cooperative ecological enterprises, 105 Tongling enterprises, and 24 typical industrial cases.

"Industrial big data" is only one of the characteristic industries of Tongdu Innovation Town. In this characteristic town, which covers an area of 3.67 square kilometers, emerging industries such as "third-generation semiconductor materials" and "Copper-based new materials" have gathered, which has promoted the construction of an innovative town to become a demonstration template for promoting the development of strategic emerging industry clusters.

In Tongling Economic Development Zone Gallium Special Semiconductor Technology (Tongling) Co., LTD., a third-generation semiconductor material - gallium nitride wafer has begun large-scale production, the enterprise is also the first large-scale production of this material in China.

It is understood that this enterprise aiming to create a new "business card" of Tongling semiconductor industry settled in Tongdu Innovation Town in May 2017, mainly engaged in the research and development, growth, manufacturing and sales of high-quality and low-cost gallium nitride substrate of 4 inches and above, which is a key investment project of Tongling City. The first-phase investment of the project is 500 million yuan, with an annual output of 100,000 gallium nitride wafers, an annual output value of 500 million yuan, an annual profit of 200 million yuan, and an annual tax of 50 million yuan.

"The gallium nitride project has brought Tongling not just a project, but a whole industry." Liu Yi, director of the Merchants Bureau of Tongling Economic Development District, said that previously, Tongling had only related packaging and other supporting industries in the semiconductor industry. The project has advanced technology, mature production process and strong industrial drive, and has broad market prospects, which is of great significance for further accelerating urban industrial transformation and upgrading and cultivating new drivers of economic growth.

The vigorous development of characteristic industries cannot be separated from policy support. In recent years, Tongling City has closely linked leading industries, strengthened investment promotion, and vigorously carried out quasi-investment promotion around the leading industry of Tongdu Innovation Town, with "science and technology" and "innovation" as the primary keywords, focusing on docking new copper-based materials research and development, big data, cloud computing, artificial intelligence and other emerging business projects.

As one of the earliest enterprises to enter the park, Cui Baosheng also witnessed the gradual growth of the town. "My hometown is here, and the government has implemented all the support policies promised to enterprises, and the enterprises are reluctant to leave once they settle down."

The growth of characteristic industries has become a "new engine" for Tongling's high-quality economic development.
