In addition, Tai Po County is also actively exploring the development mode of combining the processing of agricultural products with cultural tourism, such as the development of rural tourism projects with the theme of honeydew, to further expand the development space of the agricultural products processing industry. 3.1.2. Industry chain structure and links (1) Upstream raw material supply In the industrial chain of Tai Po County, the upstream link mainly involves the supply of raw materials. For the ceramic industry, upstream enterprises are mainly responsible for providing basic raw materials such as clay and glaze. Tai Po County has abundant clay resources, providing a solid 105 foundation for the development of the ceramic industry. However, the mining and supply of raw materials also faces a few challenges, such as the sustainability of the resources, the cost of mining, and environmental requirements. With the increasing awareness of environmental protection and the strict implementation of relevant regulations, enterprises need to pay more attention to environmental protection and the rational use of resources in the mining process. In the agricultural processing industry, the upstream segment includes the cultivation and harvesting of honeydew and tea. Tai Po County is rich in agricultural resources and is the "Hometown of China's Honeydew", with its honeydew cultivation area and output ranking among the top in the country. in 2023, the area planted with honeydew in Tai Po County reached 173,400 acres, with an output of 175,900 tonnes. In addition, the tea planting area in Tai Po County is more than 100,000 mu, mainly planting oolong tea and other varieties. These rich agricultural resources provide sufficient raw materials for the processing industry. However, seasonal fluctuations and quality control of agricultural products are also issues of concern for the upstream segment. (2) Midstream manufacturing The midstream link is the core part of the industry chain in Tai Po County, mainly responsible for processing raw materials provided by the upstream into semi-finished or finished products.

In the agricultural products processing industry, downstream enterprises have promoted products such as honey pomelo and tea to a wider market through co-operation with supermarkets and e-commerce platforms. 3.2. Industrial Strengths and Weaknesses of Tai Po County 3.2.1. Resource endowment and industrial base advantages Tai Po County has significant advantages in terms of resource endowment and industrial foundation. First, Tai Po County has rich natural resources, especially clay resources needed for ceramic industry, which provides a solid foundation for the development of ceramic industry. The clay resources in Tai Po County are not only rich in reserves, but also of excellent quality, with good plasticity and sintering properties, which are very suitable for making a variety of ceramic products. The abundance of these resources gives Tai Po County a natural cost advantage in the production of ceramics, enabling it to obtain high-quality raw materials at a lower cost, thereby increasing the market competitiveness of its products. In addition, Tai Po County's favourable geographical location at the junction of Guangdong, Fujian and Jiangxi provinces and its convenient traffic facilitate the transport of raw materials and the sale of products, further enhancing the development advantages of the ceramic industry. Secondly, Tai Po County is rich in agricultural resources, with a vast area planted with agricultural products such as honey pomelo and tea, providing ample raw materials for the agricultural products processing industry. Tai Po County is known as the "Hometown of China's Honeydew", and the planting area and output of honeydew rank among the top in the country. In 2023, the planting area of honeydew will reach 173,400 mu, and the output will be 175,900 tonnes. These high-quality honeydew resources provide a solid foundation for the development of the honeydew processing industry, and enterprises can take materials locally to produce a variety of honeydew deep-processed products, such as honeydew juice and honeydew preserved fruit. At the same time, the tea plantation area in Tai Po County is also more than 100,000 mu, mainly planting oolong tea and other varieties of tea with excellent quality and unique aroma and taste, providing abundant raw materials for the development of the tea processing industry. 3.2.2. Disadvantages such as small scale of industry and low level of technology Although Tai Po County has advantages in terms of resource endowment and industrial foundation, the problems of its small industrial scale and low technological level are also more prominent. Firstly, the scale of industry in Tai Po County is relatively small, and most enterprises in the ceramic industry and the agricultural products processing industry are small and medium-sized enterprises, with an insignificant scale effect. For example, although the number of ceramic enterprises in Tai Po County is large, but most of the enterprises are small in scale, the lack of large-scale leading enterprises to drive, unable to form a strong industrial cluster effect. This leads to enterprises in the market competition is in an unfavourable position, difficult to compete with large enterprises, in obtaining orders, negotiating prices, brand promotion and other aspects of the lack of advantage. At the same time, the smaller scale also limits the financial strength and risk-resistant ability of enterprises, in the face of market fluctuations and operational difficulties, enterprises are prone to capital chain breakage, poor management and other 106 problems, affecting the stable development of the industry. Secondly, the level of technology is relatively low, especially the lack of technological innovation. Many enterprises still use traditional processes and technologies in the production process and lack the introduction and application of new technologies. For example, in the field of agricultural products processing, key enzyme preparations and ingredients rely on imports, and domestic independent R&D and production capacity is weak, resulting in higher production costs and lower added value of products. There are also shortcomings in the loss-reducing preservation technology and intelligent cold-chain logistics technology for fresh agricultural products, and agricultural products are prone to loss and quality deterioration during transport and storage, affecting the market competitiveness of products and consumer experience. In addition, although the rare earth mining and processing industry has a certain technical foundation, the environmental protection and efficiency of the smelting and separation process still needs to be improved. The traditional smelting and separation process has high energy consumption and heavy pollution, which is not in line with the requirements of modern environmental protection and sustainable development, and the production efficiency is low, which cannot meet the market demand for high-quality rare earth products. The lack of technological level limits the further development and competitiveness of the industry in Tai Po County. It is difficult for enterprises to achieve product upgrading and industrial upgrading through technological innovation, as well as attracting high-end talents and investment, which restricts the sustainable development and high-quality development of the industry. 4.

Conclusions and Outlook 7.1. Conclusions of the Study 7.1.1. The significance of the deep integration of the industrial chain for regional economic development The deep integration of the Guangdong-Hong Kong- Macao Greater Bay Area with the industrial chain of Tai Po County has far-reaching positive impacts on the high-quality development of the regional economy. Firstly, this integration promotes the optimal allocation of resources. The Greater Bay Area possesses rich research resources, advanced technologies and a broad market, while Tai Po County has rich natural resources and a special industrial base. Through the in-depth integration of the industrial chain, the two sides can share resources and complement each other's strengths, improve the efficiency of resource utilisation, reduce production costs and enhance the added value and competitiveness of products. For example, by cooperating with advanced manufacturing enterprises in the Greater Bay Area, the ceramic industry in Tai Po County will not only be able to obtain advanced technology and equipment support, but will also be able to leverage on the market channels of the Greater Bay Area to promote its products to a wider market, thus realising optimal allocation of resources and synergistic development of the industry. Secondly, the deep integration of the industrial chain promotes industrial upgrading. Advanced manufacturing enterprises in the Greater Bay Area have significant advantages in technology research and development, product design, production management, etc. Through cooperation with enterprises in Tai Po County, they can drive technological innovation and product upgrading of industries in Tai Po County. For example, agricultural product processing enterprises in Tai Po County have improved the quality and added value of their products and promoted the upgrading of the agricultural product processing industry through the introduction of advanced processing technologies and equipment from the Greater Bay Area. Meanwhile, ceramic enterprises in Tai Po County have improved the quality and market competitiveness of their ceramic products and promoted the high-end development of the ceramic industry by cooperating with scientific research institutes in the Greater Bay Area to develop new ceramic materials and improve their production processes. In addition, the deep integration of the industrial chain also promotes the coordinated development of the regional 111 economy. Through industrial co-operation and co-ordinated development, Tai Po County can better integrate into the economic system of the Guangdong-Hong Kong-Macao Greater Bay Area, expand its market space, and enhance the overall competitiveness and sustainable development of the regional economy. For example, through docking with the industries in the Greater Bay Area, the industries in Tai Po County are better able to meet the needs of the Greater Bay Area market, while also providing more market opportunities and development space for enterprises in Tai Po County, thus promoting the coordinated development of the regional economy. 7.1.2. Effectiveness of the integration development model In the process of promoting the in-depth integration of the industrial chain between Guangdong, Hong Kong and Macao and Tai Po County, measures such as industrial docking, technological innovation and infrastructure development play an important role. Firstly, industrial docking is the foundation for achieving industrial chain integration. By clarifying the positioning and development direction of the industries of Tai Po County in the industrial chain of the Greater Bay Area, and promoting the docking and synergistic development of the industries of Tai Po County and the industries of the Greater Bay Area, the optimal allocation of resources and the complementary cooperation of industries can be achieved. For example, the ceramic industry in Tai Po County has not only enhanced the added value of its products, but also expanded its market space and realised synergistic development of the industry through cooperation with the home furnishing and decoration industries in the Greater Bay Area.

By guiding scientific research institutions in the Greater Bay Area to carry out technological research and development co- operation with enterprises in Tai Po County, and by upgrading the technological level and innovation capacity of enterprises in Tai Po County, we can promote technological upgrading and product innovation in the industry. For example, through cooperation with scientific research institutions in the Greater Bay Area, ceramic enterprises in Tai Po County have researched and developed new ceramic materials and improved production processes, which have improved the quality and market competitiveness of their products and promoted the high-end development of the ceramic industry. Once again, infrastructure development is an important support for industrial chain integration. By strengthening transport, logistics and other infrastructure construction and upgrading the level of public services, it is possible to create favourable conditions for the in-depth integration of the industrial chain. For example, by improving the transport network, Tai Po County reduces the logistics costs of enterprises, improves the competitiveness of industries, and promotes the synergistic development of industries. At the same time, by upgrading the level of financial services, talent training and other public services, it solves the financing problems of enterprises and cultivates professionals, providing strong support for the deep integration of the industrial chain. 7.2. Future Prospects 7.2.1. Opportunities arising from the accelerated integration process in the Greater Bay Area With the acceleration of the integration process of the Guangdong-Hong Kong-Macao Greater Bay Area, the industrial development of Tai Po County will usher in unprecedented opportunities. Firstly, the market integration of the Greater Bay Area will provide a broader market space for the products of Tai Po County. With the gradual elimination of trade barriers and market unification within the Greater Bay Area, Tai Po County's ceramics, agricultural products and other speciality products can enter the consumer market of the Greater Bay Area more conveniently. For example, ceramic products from Tai Po County can be supplied directly to architectural decoration companies and home renovation companies in the Greater Bay Area to meet their demand for high-quality ceramic products. Agricultural products such as honey pomelo and tea from Tai Po County can also be supplied through supermarkets, e-commerce platforms and other channels in the Greater Bay Area to quickly enter the tables of consumers in the Greater Bay Area to meet their demand for healthy and high-quality agricultural products. This will help increase the market share and brand influence of Tai Po County products and bring more orders and revenue to enterprises. Secondly, the synergistic development of industries in the Greater Bay Area will promote in-depth cooperation between enterprises in Tai Po County and the Greater Bay Area. Through the docking and integration of industrial chains, enterprises in Tai Po County can establish closer cooperation with enterprises in advanced manufacturing and modern service industries in the Greater Bay Area. For example, ceramic enterprises in Tai Po County can co-operate with ceramic design companies and brand operation companies in the Greater Bay Area to jointly carry out design research and development and brand promotion of ceramic products, so as to enhance the added value and market competitiveness of their products; agricultural product processing enterprises in Tai Po County can co-operate with food processing enterprises and catering enterprises in the Greater Bay Area to jointly develop new agricultural product processing products and markets, and to expand the application areas of their products. Such in-depth co-operation will help enterprises in Tai Po County to obtain more resources and technical support, and enhance the overall competitiveness and innovation capacity of the industry. In addition, the infrastructure connectivity in the Greater Bay Area will provide better conditions for industrial development in Tai Po County. With the continuous improvement of transport, logistics, information and other infrastructures, Tai Po County will be more closely connected to the Greater Bay Area. For example, with the construction and renovation of the main transport routes from Tai Po to Meizhou and from Tai Po to Chaozhou, the transport conditions in Tai Po County will be significantly improved, and the transport time for enterprises' products will be shortened and the logistics cost will be reduced, which will help to improve the market responsiveness and competitiveness of enterprises. At the same time, the improvement of information infrastructure will promote the rapid circulation and sharing of information, enterprises can more timely access to market information, technical information and policy information, etc., to provide strong support for enterprise decision-making and innovation. 7.2.2. Continuously deepening the direction of industry chain integration In order to seize the opportunities brought about by the integration process of the Greater Bay Area, Tai Po County 112 needs to continue to deepen the integration of the industrial chain and promote the development of industries towards high-end, green and intelligent development. Firstly, high-end development is the key to enhancing industrial competitiveness. Tai Po County should strengthen technological innovation and product research and development, improve the technological content and add value of products, and advance to the high-end market. For example, in the ceramic industry, develop high-end ceramic products with independent intellectual property rights, such as the use of nanotechnology, biotechnology and other cutting-edge technologies, to develop ceramic products with special functions and artistic value, to meet consumer demand for high-quality, personalised products. At the same time, strengthen the brand building, enhance the brand awareness and reputation of the products, and enhance the market competitiveness and added value of the products. In addition, advanced technology and management experience can be introduced to promote the high-end development of the industry through co-operation with scientific research institutions and enterprises in the Greater Bay Area. Secondly, greening development is an inevitable choice for achieving sustainable development. Tai Po County should strengthen environmental protection and resource conservation, promote green production technologies and techniques, and reduce pollution of the environment and waste of resources. For example, in the agricultural products processing industry, it adopts environmentally friendly processing equipment and processes, such as adopting energy-saving processing equipment and processes that reduce wastewater discharge, to improve the greening level of products. At the same time, the recycling of waste and the recycling of resources should be strengthened, for example, in the ceramic industry, the waste and wastewater generated in the production process should be recycled to reduce the waste of resources and environmental pollution. In addition, the development of green energy, green packaging, etc., can also be used to reduce the carbon emissions and environmental impact of the industry, to achieve the green development of the industry. Finally, intelligent development is an important direction for industrial transformation and upgrading. Tai Po County should accelerate the in-depth integration of information technology and industry, and promote the intelligent transformation and upgrading of industry. For example, in the manufacturing industry, intelligent production equipment and management systems, such as industrial robots, automated production lines, intelligent manufacturing systems, etc., are introduced to improve the automation and intelligence level of production, reduce production costs, and improve production efficiency and product quality. At the same time, the application of information technology such as big data, artificial intelligence and the Internet of Things is strengthened to achieve intelligent management and optimisation of the production process, and to improve the production management level and market response speed of enterprises. In addition, intelligent management and optimisation of the supply chain can be achieved through the establishment of an intelligent supply chain management system to improve the efficiency and responsiveness of the supply chain. By continuing to deepen the integration of industrial chains and promoting the development of industries in the direction of high-end, green and intelligent, Tai Po County will be able to better integrate into the economic system of the Guangdong-Hong Kong-Macao Greater Bay Area, realise the sustainable and high-quality development of industries, and make greater contributions to the development of the regional economy.
