To build a modern socialist country in all respects, we must, first and foremost, pursue high-quality development. With strong economic strength, rich innovation resources and developed market economy, the Guangdong–Hong Kong–Macao Greater Bay Area is one of the regions with the highest degree of openness and strongest economic vitality in China. Over the past four years since the issuance of the Outline of the Development Plan for the Guangdong–Hong Kong–Macao Greater Bay Area, the Greater Bay Area has taken the lead in high-quality development and set an example, achieving remarkable results. Significant progress has been made in improving the transportation network and building modern infrastructure in the Greater Bay Area in terms of transportation network connectivity. In terms of rail transit, Guangzhou, Shenzhen and other metropolitan areas accelerated the construction of subway and Inter-city rail; In terms of airport construction, Hong Kong, Guangzhou, and Shenzhen serve as the core international airports in the Greater Bay Area, connecting with the air transportation network nodes in the Greater Bay Area such as Zhuhai and Macau, forming a world-class airport cluster; In terms of shipping hubs, Dawan District has coastal ports such as Hong Kong Port, Port of Guangzhou, Port of Shenzhen, Zhuhai Port, Dongguan Port, and inland ports such as Foshan Port and Zhaoqing Port, leading the country in shipping connectivity and port throughput. Looking ahead, the Greater Bay Area can fully leverage the supporting role of infrastructure to promote high-quality development of the real economy. For example, accelerating the formation of a high-speed rail transit network supported by the "Greater Bay Area on the Rail"; Breaking through logistics transportation bottlenecks and accelerating the construction of modern circulation networks; Improve the transportation system and mechanism, and improve the efficiency of transportation accessibility. At the same time, we will continue to accelerate the construction of "New Infrastructure" such as 5G base stations, Big data centers, artificial intelligence, and industrial Internet in inland cities of the Greater Bay Area, and accelerate the formation of a smooth internal circulation "New Infrastructure" network. Optimize the industrial structure and promote the high-quality development of the manufacturing industry. The Greater Bay Area has initially formed a modern industrial system with international competitiveness. The advanced manufacturing industry has developed rapidly, the electronic information industry belt on the east bank of the the Pearl River with international influence has begun to take shape, and the high-end equipment manufacturing belt on the west bank is under construction; Strategic emerging industries are constantly growing, and industries such as integrated circuits, biopharmaceuticals, and new energy and materials are rapidly emerging. Strategic emerging industry clusters are emerging; The modern service industry is accelerating its development, and the regional productive service industry is developing towards specialization and high-end extension of the value chain; The rapid rise of the marine economy has led to the rapid development of the marine transportation industry and marine equipment manufacturing industry. The manufacturing industry is the main body of the real economy. The Greater Bay Area can expand the scale of advanced manufacturing industry, consolidate the foundation of manufacturing development, continuously cultivate and expand the scale of industrial clusters, accelerate the transformation of development momentum, and promote the intelligent, digital, and green transformation of the manufacturing industry; Optimize industrial layout, promote regional synergy and linkage, and form a reasonable industrial division of labor pattern; Accelerate the pace of high-end manufacturing, promote the two-way integration of manufacturing and service industries, promote the transformation and upgrading of traditional manufacturing and the upgrading of industrial structure, especially improve the Total factor productivity and scientific and technological contribution rate of leading industries. Innovation drives development and leverages the support of the International Science and Technology Innovation Center. Technological innovation is the key to high-quality development in the Greater Bay Area. As of May 2023, the Greater Bay Area has established 34 national and 71 provincial-level international science and technology cooperation bases, 20 Guangdong Hong Kong Macao joint laboratories, Pengcheng Laboratory and Guangzhou Laboratory, and the comprehensive level of scientific and technological innovation has reached a full level
