— To promote the construction of Guangdong, Hong Kong and Macao Bay area is a major decision made by the Party Central Committee, a new measure to promote the formation of a new pattern of comprehensive opening-up in the new era, and a new practice to promote the development of the cause of "one country, two systems". Promoting the construction of the Great Bay area of Guangdong, Hong Kong and Macao is conducive to deepening exchanges and cooperation between the mainland and Hong Kong and Macao, and is of great significance for Hong Kong and Macao to participate in national development strategies, enhance competitiveness and maintain long-term prosperity and stability. From the perspective of smart supply chain, this paper proposes to build a smart supply chain system in Guangdong, Hong Kong and Macao to promote high-quality economic development.


Introduction
Promoting the construction of the Great Bay Area in Guangdong, Hong Kong and Macao is a major decision made by the Central Committee of the CPC Central Committee with Comrade Xi Jinping as the core. It is a national strategy of general secretary Xi Jinping himself, who plans, personally deploys and personally promote [1,2]. It is a new measure to promote the formation of a new pattern of comprehensive opening in the new era, and is also a new practice to promote the development of "one country two systems" [3,4]. Promoting the construction of the Great Bay area of Guangdong, Hong Kong and Macao is conducive to deepening exchanges and cooperation between the mainland and Hong Kong and Macao, and is of great significance for Hong Kong and Macao to participate in national development strategies, enhance competitiveness and maintain long-term prosperity and stability [5,6].
At present, the economy of our province has entered a new period of high-quality development from the stage of high-speed growth. Economic development is faced with the problems of insufficient effective demand, low quality and efficiency of supply side system. The supply side structural reform, which focuses on capacity reduction, inventory reduction, leverage reduction, cost reduction, and weakness compensation, is a major strategic measure to enhance the driving force of sustained economic growth, solve deep-seated problems in economic development, and improve the quality of economic development. It has been proved that the smart supply chain has significant effect on promoting the supply side structural reform of our province in the aspects of inventory removal, cost reduction, solution of supply and demand dislocation, and promotion of industrial transformation and upgrading. The CPC Central Committee and the State Council attached great importance to the innovation and application of supply chain. Xi Jinping, general secretary of the CPC and Premier Li Keqiang put forward the optimization and innovation of supply chain on many occasions. According to the report of the 19th National Congress of the Communist Party of China, we should cultivate new growth points and form new momentum in the fields of middle and high-end consumption, innovation leading, green and low-carbon, sharing economy, modern supply chain, human capital service, etc. In October 2017, the guidance on promoting supply chain innovation and application issued by the general office of the State Council proposed that "by 2020, a smart supply chain system covering China's key industries will be basically formed" to accelerate the innovation and application of smart supply chain, which has become an important part of promoting supply side structural reform, cultivating new economic growth points and building a modern economic system. As smart supply chain is still a new theoretical concept, the related research at home and abroad is still in the primary stage [7]. According to the industry research report, the supply chain industry has an important impact on economic development, as shown below: Table 1 impact of supply chain industry   Symbol supply chain industry  Proportion  A  proportion of supply chain  industry in total fiscal revenue  and employment   6%   B impact of supply chain industry on social economy and other industries 12% C competition and innovation capacity of supply chain industry 5% In 2019, the scale of the supply chain industry will reach 240 billion Yuan, and the market speed will remain above 10% from 2011 to 2019.

Research Trends of Foreign Smart Supply Chain
The research of smart supply chain is just 10 years old, and it is still in its infancy. It was first proposed by IBM in 2008 that the smart supply chain is a part of IBM's smart earth. In 2009, IBM pointed out the five problems existing in the current supply chain, including cost control, supply chain visibility, risk management, increased user demand, globalization, etc. through the global chief supply chain officer survey report, and believed that the future supply chain should develop in the direction of advanced, interconnected and intelligent. Through the literature review, it can be seen that the research on smart supply chain in literature mainly focuses on four parts: information management of supply chain, Internet of things based on its technology, process automation and big data analysis, and has not yet formed a complete smart supply chain system. For the information management in the smart supply chain, it is mainly focused on the demand (or order) information management between node enterprises. The research shows that intelligent supply chain manufacturing provides accurate, high-quality and timely information, and has controllability for information supply chain and protection. In the research of it based Internet of things, it is found that smart devices and sensors can greatly improve the visibility of supply chain, improve manufacturing efficiency and efficiency, reduce inventory, prevent out of stock, avoid inventory surplus and improve data accuracy, which is helpful to create unique value for all stakeholders in the supply chain. However, the research of intelligent supply chain in process automation mainly focuses on manufacturing, purchasing, warehouse, distribution and retail (Trebilcock, 2013). Research on big data believes that big data can create great value for the world economy, improve the productivity of companies and public sectors, and create a large amount of economic surplus for consumers. Barton & Court (2012) pointed out that smart supply chain requires enterprises to obtain correct data, establish models to predict and optimize business output, and transform them into organizational processes. Among them, data mining is an important method to discover and interpret data patterns. In addition, some enterprises have tried and explored some ideas of smart supply chain in practice, but most of them are based on the cognition of individual enterprises, which is not universal.

Research Trends of Domestic Smart Supply Chain
The concept of "smart supply" was first proposed by Dr. Luo Gang of Fudan University in 2009 at the Shanghai Conference on integration of informatization and industry. After that, scholars began to pay more and more attention to the intelligent supply chain. Zhai Dufeng (2011) believed that the intelligent supply chain is to embed the intelligent information network technology into the supply chain, realize the high-level integration of information technology, and build a networked, information-based and intelligent supply chain network. Zhang Yuchuan (2012) believes that smart supply chain is to use advanced technologies such as Internet of things and big data to manage all enterprises and their business behaviors in the supply chain by intelligent means, so as to realize the smart operation of the supply chain. Liu Zhigang (2015) believed that "smart supply chain" is an integrated system of intelligence, networking and automation, which is constructed by applying the innovation results of Internet of things and artificial intelligence, combining with the theory, method and technology of modern supply chain management, to better grasp the relevant information of upstream and downstream enterprises, and to realize seamless connection of logistics, information flow and capital flow. Zhou Yongsheng (2015) described the characteristics and development direction of smart supply chain, and proposed to solve the constraints of supply chain from various aspects. Song Hua (2015) explored theoretically the core of "Internet plus", which is to promote the supply chain transformation of the three industries and realize the intelligent supply chain. The innovation of smart supply chain can be reflected in three key elements of Supply Chain Management: Six ability systems formed on the elements; information governance constructed on the structure; intelligent decision-making, operation visualization, Organization Ecology and element integration realized on the process. Based on the above scholars' research, scholars basically believe that intelligent supply chain needs to rely on all kinds of advanced science and technology, so that members of the supply chain can achieve seamless docking in information flow, logistics, capital flow and other aspects, and realize the complete sharing of information, so as to achieve the intellectualization, networking and informatization of the supply chain.

Literature Review
With the extensive and in-depth application of cloud computing, artificial intelligence and other information technologies, the supply chain is deeply integrated with the Internet and the Internet of things, and supply chain management begins to enter a new stage of intelligent supply chain. However, the research of smart supply chain is still in its infancy, and the existing research tends to be fragmented. First, at present, the understanding of smart supply chain from all walks of life is not unified. Compared with the developed countries, our country has no deep understanding of the essence of smart supply chain, some case studies cannot form an effective discipline system and practical guidance, so it is urgent to build a theoretical system.
Second, the construction of smart supply chain system in China and our province is still in the exploratory stage, with weak foundation. From the overall situation of supply chain system construction in China, problems such as inadequate understanding of smart supply chain, lack of smart supply chain strategy, low level of logistics informatization, large number of information islands, lack of professional talents are still outstanding, lack of systematic policy recommendations, and cannot effectively guide the implementation of innovation, development and application of supply chain.
Thirdly, the theoretical research of smart supply chain management is mostly limited to the micro field of a certain industry or a certain link of the supply chain, which has not really combined the supply side reform and the construction of smart supply chain system in China. More literatures use the general theories and tools of "Internet +", big data, artificial intelligence and other information technologies to describe the basic idea of smart supply chain. They do not systematically plan the smart supply chain system and implementation roadmap of key industries, which easily leads to narrow research conclusions that only trees and forests are seen.

Construction Ideas of Smart Supply Chain System
Supply chain is an organization form which is oriented by customer demand, aims at improving quality and efficiency, and integrates resources to realize the whole process of product design, procurement, production, sales, service and other efficient collaboration.
