The Cross-Strait Information Appliance Industry Park settled in Huai’an
At the main forum of the 10th Taiwan Business Forum, the Cross-Strait Information Appliance Industry Park was grandly inaugurated and marked The mainland’s first cross-strait information appliance industrial park officially settled in Huai’an. It is understood that in June this year, the Cross-Strait Entrepreneurs Summit formally agreed to establish a Cross-Strait Information Appliance Industrial Park in Huai'an. Its establishment has further boosted Huai’an’s high-end talent gathering, high-tech innovation, and high-value-added electronic information industry chain, promoted the integrated development of cross-strait electronic information industries, and added a new platform for Huai’an to build a Taiwan-funded highland. New momentum. As CCTV special commentator Yang Yu said: “This is another result of the integration and development of the two sides of the strait under the new situation, and it has also injected new connotations into the construction of the Taiwan-funded highland in Huai’an.” In recent years, the development of the information appliance industry in our city has entered. Fast lane. With Foxconn, Zhending Technology, BenQ Darfon Electronics, Minth Electric Vehicles and other leading companies in the world’s top 500 or information appliance industry settled in the development zone, the information appliance industry has gradually emerged, the industrial structure has been continuously upgraded, and the computer has gradually formed The relatively complete information appliance industry chain, such as connectors, displays, keyboards, electronic components, PCB multilayer circuit boards, and smart TV sets, has developed into one of the city's four leading industries.
Huai’an has been rated as a “highly recommended city” for Taiwanese investment by the Taiwan Electric Power Association for 4 consecutive years, and has successfully created the country’s first and only national-level Taiwan-funded enterprise industrial transfer cluster service demonstration zone. It has won the favor of the majority of Taiwanese businessmen. Let storage no longer become an annoyance.
According to the relevant person in charge of the Municipal Taiwan Affairs Office, the development of the information appliance industry in our city will mainly focus on three types of industries: one is to highlight a major core industry, that is, to introduce Foxconn and its computer supporting industries as the core Intelligent information terminal and core component projects, build intelligent terminals and supporting industrial bases and industrial clusters, and form an industrial chain with complete system, reasonable division of labor, and supporting upstream and downstream as soon as possible.
The second is to enhance characteristic industrial clusters, that is, around smart terminals, actively adjust the product structure of electronic components, and promote the development of electronic components to high-end, lighter and thinner, energy-saving and environmentally friendly, and diversified; speed up green energy, Technological upgrades in electrical and mechanical industries such as cables; promote the deep integration of industrialization and informatization, and create applied electronics industry clusters.
The third is to cultivate potential growth industries, namely software and information service industries, relying on LCD TV, smart TV and tablet PC projects, vigorously introduce new display device projects; develop LED epitaxial wafers, chip manufacturing, and LED chips Package applications, etc.; accelerate the development of cloud computing, Internet of Things and Internet + related software and information service industries to create "Smart Huai'an".
The specific implementation process will be divided into four steps, namely, by selecting business and attracting capital, expanding the scale of the information industry; extending the industrial chain, and building an industrial ecology led by large enterprises and coordinated development of small and medium-sized enterprises. System; strengthen technological innovation and business model innovation, seize the commanding heights of the value chain; strive to achieve innovation breakthroughs in some key links of the industrial chain, and control pricing power.
