The recent symposium on promoting regional coordinated development in the province proposed to focus on the construction of the Guangdong Hong Kong Macao Greater Bay Area, strengthen the important driving force for high-quality development, focus on creating innovative sources, accelerate the construction of high-level innovation platforms, gather high-level innovative talents, deepen key core technology research and development, and promote more new quality productivity. At present, we need to deepen cooperation between Guangdong, Hong Kong, and Macao around the new positioning of "one point, two places" in the Guangdong Hong Kong Macao Greater Bay Area, better play the supporting and driving role of the Greater Bay Area, deepen the construction of the "Digital Bay Area", empower the development of new quality productive forces with the "digital engine", and effectively activate the endogenous driving force of high-quality development in Guangdong. 1、 Unleashing innovation potential through the "Digital Bay Area" is different from traditional economic growth methods and productivity development paths. New quality productivity is an advanced productivity that is born from revolutionary technological breakthroughs, innovative allocation of production factors, and deep industrial transformation and upgrading. The Guangdong Hong Kong Macao Greater Bay Area has abundant data resources, complete information infrastructure, and a complete industrial chain, making it a gathering place for innovative elements. Through this, digital technologies such as artificial intelligence and big data can iteratively upgrade and accelerate development. Therefore, seizing the new track of the digital economy and striving to build a "digital bay area" will accelerate the production of more new quality productivity. Promoting high-quality development of the digital economy through technological innovation and promoting the leap of new productive forces. The purpose of building a "Digital Bay Area" is to drive the transformation and upgrading of the economic form of the Greater Bay Area through the digital economy and generate a demonstration effect. As the main engine of the "Digital Bay Area", the digital economy is a new economic form characterized by intelligence, networking, and platformization, with digital technology as the core and technological and institutional innovation as the "dual driving forces". In the context of increasingly fierce competition in the global digital economy, data has become an important production factor to enhance the competitive advantage of the "Digital Bay Area". After data entered the production field, it gave birth to digital technologies such as artificial intelligence and blockchain. On this basis, enterprises in the Greater Bay Area can comprehensively utilize data, information, and technology to achieve digitalization of production processes and intelligent management decisions, optimize the input structure and organizational methods of production factors, and stimulate workers to continuously improve their digital literacy, promote knowledge spillover and specialized division of labor, thereby activating and giving birth to more new quality productivity in the Greater Bay Area. Drive technological innovation with digital technology and unleash the development potential of new productive forces through the integration of data and reality. To build a "digital bay area" and achieve high-quality development of the digital economy, it is necessary to promote the deep integration of digital technology and the real economy, clarify the development path of deepening research and development applications such as big data and artificial intelligence, and building a digital industry cluster with international competitiveness. Specifically, we will focus on strengthening the digital "base connectivity" to provide strong computing resources for the digital economy of the Greater Bay Area. On this basis, efforts will be made to leverage the leading role of the digital economy in transforming production methods and optimizing economic structure. On the one hand, driving technological innovation with digital technology, changing the growth mode of the real economy, and promoting the transformation of traditional manufacturing towards digitization, intelligence, and networking; On the other hand, leveraging the technological support of the digital economy for the transformation and development of the real economy, empowering various fields of the real economy with digital intelligence, promoting the interconnection and mutual promotion of industrial chains, supply chains, and value chains, giving rise to new forms and models of industry, promoting the agglomeration and development of the digital industry, cultivating a number of future industries and strategic emerging industries, and stimulating the continuous emergence of new quality productivity. Promoting the free flow and innovative combination of resource elements through institutional innovation, and giving birth to more new quality productive forces. The three regions of Guangdong, Hong Kong, and Macao have established a joint working mechanism for the "Digital Bay Area", created a comprehensive service platform for "Bay Affairs Communication" to promote the "Cross border Communication" of government services, and accelerated the coordination of systems such as the intelligent construction of cross-border dedicated ports and the Guangdong Hong Kong Macao Information Cooperation Zone. At the same time, we will sign cooperation agreements for smart city clusters, explore a "whitelist" system for cross-border data circulation, strengthen the sharing and utilization of smart city data elements such as economic data, spatial geography, and transportation information, promote the free flow and optimized allocation of human resources, data, technology, and other elements in Guangdong, Hong Kong, and Macao, and use data flow to drive the flow of people, logistics, funds, and technology, promote the integration of the four chains of industry, innovation, talent, and education, continuously improve the transformation and industrialization level of scientific and technological achievements in the Greater Bay Area, and drive the accelerated development of new productive forces. 2、 At present, the development of the digital economy in the Greater Bay Area is still uneven, especially in terms of cross-border data flow, rights confirmation, transactions, cooperation, and supervision in Guangdong, Hong Kong, and Macao, which has led to the transformation of the "Digital Bay Area" from a "construction drawing" to a "real-life painting". There are still institutional obstacles, forming a bottleneck for the "Digital Bay Area" to unleash the potential for the development of new productive forces. Therefore, while drawing the "construction drawings" of the Digital Bay Area, efforts should be made in multiple directions to promote the transformation of the "Digital Bay Area" from "construction drawings" to "real-life paintings". Building a solid foundation for the Digital Bay Area and accelerating the expansion of digital technology application scenarios. Data is a key element in the development of the digital economy. It is necessary to build a new data infrastructure that adapts to the characteristics of data resources, promotes the circulation and use of data, and releases the value of data elements, paving the way for the high-quality development of the digital economy in the Greater Bay Area. Accelerate the broadband expansion of international Internet access, strengthen the interconnection between the network and data in the Greater Bay Area, comprehensively promote the infrastructure construction with information transmission as the core, and transform and upgrade to a new generation of information infrastructure such as integrated perception, computing, processing, etc. At the same time, we will establish a "credible digital space" in accordance with the law, accelerate the coordinated development of supercomputing centers, edge computing centers, and other diversified industries, and help the construction of the "international data port" in the Greater Bay Area. On this basis, by utilizing various security technologies such as trusted data chains, we promote the secure and orderly flow and transactions of cross-border data, empower the leap and high-level application scenarios of digital technologies such as artificial intelligence, and give birth to more new quality productivity. Accelerate the deep integration of industry, academia, research and application, and strengthen the core industries of the digital economy in the Guangdong Hong Kong Macao Greater Bay Area. Give full play to the role of the Greater Bay Area Digital Economy Alliance, link with the governments, enterprises, universities, and research institutions of the three regions in the Greater Bay Area, and build a data empowerment integrated platform through the establishment of modern industrial colleges, talent training demonstration bases, and other methods. Establish and improve intellectual property protection mechanisms and venture capital mechanisms, and comprehensively build a coordinated development system of "politics, industry, academia, research, application, and investment". On this basis, we will increase investment in basic research and promote schools, enterprises, and research and development institutions in the Greater Bay Area to focus on key technologies in fields such as artificial intelligence and life sciences in the form of "unveiling and leading". We will empower various industries in the Greater Bay Area with talent and scientific research advantages to improve their intelligence and efficiency, and use the technology chain to drive the industrial chain and value chain up to the high-end, improving the core competitiveness of the digital industry. At the same time, leveraging the empowering effect of "artificial intelligence+data" elements, we will continue to promote the deep integration of data and reality, constantly give rise to new business models and formats that meet market demand, such as networked collaborative manufacturing, large-scale personalized customization, and remote intelligent services. We will cultivate world-class emerging industries and future industrial clusters, and stimulate the emergence of new quality productivity. Strengthen institutional innovation and smooth the flow channels of innovative elements in the Greater Bay Area. According to the Memorandum of Cooperation on Promoting Cross border Data Flow in the Guangdong Hong Kong Macao Greater Bay Area, we will accelerate the improvement of the national data cross-border security management system, establish rules for cross-border data flow in the Guangdong Hong Kong Macao Greater Bay Area, and refine the standardization process of data collection, processing, storage, and sharing, as well as strengthen the data classification and hierarchical management system. At the same time, leveraging the policy advantages of major cooperation platforms such as Hengqin, Qianhai, Nansha, and Hetao, we will promote institutional innovation in cross-border data flow and cooperation in the Greater Bay Area. On this basis, we will improve the digital literacy and ethical awareness of scientific and technological talents in the Greater Bay Area, establish a trust mechanism for data sharing and utilization in the Greater Bay Area, broaden the institutional space for data flow in the Greater Bay Area, and continuously release benefits for the smooth flow of funds, industrial development, and social governance in the Digital Bay Area. This will greatly improve the efficiency of social resource allocation and effectively promote the accelerated development of new productive forces. (Lai Xin She)
