The Tenth Five-Year Plan of many provinces suggests introducing key words such as industrial chain modernization and digital economy.

Recently, Anhui, Hubei, Jiangxi, Hunan and other central provinces have successively announced suggestions on formulating the 14th Five-Year Plan for national economic and social development and the long-term goals for the year 2035 (hereinafter referred to as the "14th Five-Year Plan" suggestions).

At the level of industrial planning, the central provinces have their own emphases, but they all emphasize the need to strengthen the toughness of the supply chain industry chain, build a long board of the industry chain and build a modern industrial system.

Jiangxi's "14th Five-Year Plan" suggests that we should fight hard to upgrade the industrial base and modernize the industrial chain. Vigorously promote the chain length system of industrial chain, and promote the casting chain to strengthen the chain. We will improve the diversified supply system of core components and key raw materials, and strive to fill the shortcomings of basic components in key areas such as smart sensors, industrial software, rare earth functional materials and integrated circuit silicon wafers.

Anhui proposed to improve the stability and modernization level of the industrial chain supply chain. We will implement the action of supplementing and strengthening the chain, implement the system of long industrial cluster, long industrial chain supply chain and long industrial alliance, forge the long board of industrial chain supply chain, and cultivate and form 1 trillion-level industries, 10 major industries above 100 billion level and "chain-long" enterprises 100.

Strengthening the digital economy, promoting digital industrialization and industrial digitalization have also been written into the "14 th Five-Year Plan" suggestions of the central provinces.

Jiangxi proposed to implement the "No.1 Project" of the digital economy and gather and expand the digital industry. Make good use of the platform of the World VR Industry Conference, accelerate the landing and demonstration application of industrial projects, and strive to build a world-class VR center.

Anhui proposed to build a pioneer area of digital science and technology innovation and a cluster area of digital economy industry. Construction of Hefei National New Generation Artificial Intelligence Innovation and Development Experimental Zone, striving for National Digital Economy Innovation and Development Experimental Zone, China Software Park and China Software City. Make "China Sound Valley" bigger and stronger. Accelerate the construction of Jianghuai Big Data Center and Anhui (Huainan) Big Data Trading Center.

Optimizing regional development layout and strengthening regional cooperation also occupy an important position in the "14 th Five-Year Plan" proposal of central provinces. While making provincial capital cities bigger and stronger, all provinces emphasize the need to speed up the construction and development of urban agglomerations and cultivate regional economic power sources.

Hunan proposed to build a regional economic pattern of "one core, two pairs, three belts and four districts". "Two pairs" refers to the construction of Yueyang and Hengyang, two provincial sub-central cities. Jiangxi proposes to improve the regional development pattern of "one circle leading, two-axis driving and three-zone cooperation", including: strengthening and improving Nanchang metropolitan area; Create the main axis of high-speed rail economic development in Shanghai-Kunming and Beijing-Kowloon; Promote the high-quality development of the former Central Soviet Area such as Gannan. Hubei puts forward the regional development layout of "one leader leading, two wings driving and global coordination", including: giving full play to Wuhan's leading and radiating role as a national central city and a core city in the Yangtze River Economic Belt; Promote the urban agglomeration of "Shixiang following the spirit" and "Yijing Jing En" to develop from a point axis to a sector, and build the north-south "wings" that support the high-quality development of the province.
