Throughout the 5,000-year history of Chinese civilization, people often think of the incomparably brilliant inland civilization, and ignore the positive deeds and outstanding achievements of our maritime civilization, and even the famous modern philosopher Hegel once said that China is a country that "does not have a positive relationship" with the sea. In fact, since ancient times, China has been a country with "back land and sea", with both vast land and vast maritime land, creating a brilliant land civilization and an advanced marine civilization at the same time. According to archaeologists, the primitive ancestors who lived in this ancient land tens of thousands of years ago began to contact the ocean, conduct organized exploration of the sea, and obtain food resources from the ocean. Subsequently, ships were built to carry out overseas transportation, and in "Zhou Yi", "Wood for boats, wood for boats, the benefits of boats, to help the impossible, to benefit the world" is a record of the boat-building methods and the value of boats during the period of the Three Emperors and Five Emperors. In the Book of Shang, "Daoyi Hui clothing, Yu Yu weaving shells, Yu Bao orange, pomelo, Xigong." Along the Jianghai River and the Huaisi River" records the transportation and economic ties with overseas "island Yi" countries at that time. In the "History of Goods and Colonies", "Panyu, also a metropolis, pearl, rhinoceros, tortoiseshell, fruit, and cloth" records the overseas trade exchange products of China's early Yin merchants' seaport - "Panyu Port". During the Spring and Autumn and Warring States periods, the coastal princes attached great importance to the exploration of the sea, but also attached great importance to the protection of their own maritime interests, so they developed a sense of sea power and began to organize maritime armed forces. After the Qin and Han dynasties, maritime civilization began to prosper, especially after Emperor Wudi of Han, he opened up water communication routes with the South China Sea countries and the Indian peninsula, and engaged in regular trade, which is the famous "Maritime Silk Road". During the Tang Dynasty, economic and trade exchanges with overseas countries were frequent, large ports were built along the coast, and maritime traffic was more developed, starting from Dengzhou, Yangzhou and other ports, you can reach today's Japan and South Korea, starting from Guangzhou, you can reach the Persian Gulf through the maritime "Silk Road". During the Two Song Dynasty, overseas trade became more prosperous, and ports and maritime traffic were further developed. In the Ming Dynasty, Zheng He led a fleet to the Western Ocean seven times, and its scale, large number, long time, and long voyage created a miracle unique in the world at that time, which not only promoted the national prestige, but also greatly strengthened the political and economic ties with overseas countries. However, that is, the Ming Dynasty began to ban the sea and lock the country, from Zhu Yuanzhang's repeated bans to the "plates are not allowed to enter the sea" after the middle of the Ming Dynasty, and then to the Qing Dynasty's further ban on the sea, the long-prosperous marine civilization of the Chinese nation went into decline, in sharp contrast to the vigorous development of the world's marine civilization in the same period. The implementation of the policy of banning the sea and closing the country has caused China to lose the initiative in foreign trade, hindered the budding development of capitalism, blocked exchanges and docking with advanced civilizations, and attracted continuous aggression by modern powers, and Chinese civilization has since begun to decline in an all-round way. "Realizing the great rejuvenation of the Chinese nation" is the great "Chinese dream". Rejuvenating marine civilization and realizing maritime power can be said to be China's great "ocean dream". The "Ocean Dream" is an important part of realizing the "Chinese Dream" and an important strategy and path for realizing the "Chinese Dream". Focusing on this dream, modern benevolent people have deep thinking, and the most famous representative figure Wei Yuan's book "Picture of the Sea Country" puts forward an ideal blueprint for building a "sea country" as never before. Beginning with Sun Yat-sen, several generations of leaders in modern times have put forward the idea of a maritime power with great foresight with the unique wisdom and strategic vision of great statesmen. Sun Yat-sen advocated the active development of marine industry and fought for China's maritime rights and interests. Mao Zedong attached great importance to naval construction and the development of maritime undertakings, and proposed that a powerful navy must be built. Deng Xiaoping also attached great importance to the building of naval forces, repeatedly stressed "developing maritime undertakings and revitalizing the national economy," and creatively put forward the far-sighted vision of "shelving disputes and jointly developing" to resolve island disputes. The third-generation leader with Comrade Jiang Zemin as the core put forward for the first time at the 16th CPC National Congress the "goal of implementing the marine development strategy." The central leadership with Comrade Hu Jintao as general secretary stressed the need to enhance maritime awareness and publicly declared for the first time that China is a maritime power. In the report of the 18th National Congress of the Communist Party of China, the construction of a maritime power was officially included in the national strategy. On July 30, 2013, General Secretary Xi Jinping presided over the eighth collective study of the Politburo of the CPC Central Committee and stressed that building a maritime power is an important part of the cause of socialism with Chinese characteristics; In October 2013, General Secretary Xi Jinping put forward the major strategic concept of "building the 21st Century Maritime Silk Road" during his visit to ASEAN countries. The maritime ideas of people with lofty ideals and great statesmen constitute the rich connotation of China's "Ocean Dream". How to realize the "Ocean Dream"? The Fifth Plenary Session of the 17th Central Committee of the Communist Party of China adopted the "Twelfth Five-Year Plan" for national economic and social development, which clearly put forward "adhering to the overall planning of land and sea, formulating and implementing marine development strategies, improving the ability of marine development, control and comprehensive management, and promoting the development of the marine economy". Broadly speaking, "land-sea coordination" is based on fully understanding that China has the dual attributes of land power and maritime power, and takes land and sea area as an overall strategic overall planning; In a narrow sense, "land-sea integration" mainly belongs to the category of regional economy, that is, integrating the advantages of land and sea resources in the region to promote regional economic development. "Land-sea economic integration" and "land-sea economic integration" are the mainstream directions of research on "land-sea integration" and "land-sea integration". On January 23, 2013, the State Council officially approved the "Zhejiang Zhoushan Archipelago New Area Development Plan", which clearly requires the new area to actively explore a new path for the scientific development of marine economy, strive to create a new model of comprehensive protection and development of marine islands, constantly innovate the overall planning and coordination mechanism of land and sea, effectively promote the development and opening up of Zhoushan Archipelago New Area, and develop well and rapidly, and become a pioneer area and demonstration area for the coordinated development of land and sea in the country. Shandong, Guangdong and other places have also actively begun similar explorations. Regarding "land-sea economic integration" or "sea-land economic integration", although relevant concepts have been proposed at home and abroad, and relevant research has been carried out, most of the research is scattered and fragmented, this book "Research on Maritime and Land Economic Integration in the South China Sea" aims to carry out a new and systematic exploration in this field, and strive to form its own characteristics and innovations in the following aspects: First, the perspective is unique, starting from the South China Sea issue, and closely linking the national marine strategy and the South China Sea strategy. That is, to study the theory and practice of land and sea economic integration from a new perspective, and at the same time provide new strategic thinking for effectively solving the South China Sea issue and maintaining security and stability in the South China Sea. Second, with the South China Sea as the "central area", according to the degree of development and utilization of the resources of the South China Sea in the South China Sea area, as well as factors such as geographical location, sea and land transportation, sea-land economic linkage capacity and differences in the industrial structure of sea and land, the spatial level of sea-land economic integration in the South China Sea is divided into the central area of the South China Sea, the inland radiation area and the international cooperation zone, and the research is carried out from a broader perspective at home and abroad. The third is theoretical innovation, which conducts more systematic and creative research on the connotation, characteristics, scope, power, mechanism and other basic theories of sea and land economic integration, such as revealing the characteristics of sea and land economic integration from the perspective of location theory, and at the same time, based on the linkage and coordination of marine economic location and land economic location, scientifically define the scope of sea and land economic integration, and research and propose the integration of six aspects such as sea and land economic space, resource industry, production factors, infrastructure, ecological environment and so on and run through the research of the whole book. The fourth is to pay attention to reality, attach importance to theoretical innovation and the high degree of integration of practical concerns, not only study the great strategic significance of land and sea economic integration for maintaining security and stability in the South China Sea, promoting the implementation of the maritime power strategy, promoting the construction of an "upgraded version" of the China-ASEAN Free Trade Area, and deepening cooperation with Hong Kong, Macao and Taiwan, and at the same time taking Guangxi's "maritime power zone" as an example to deeply discuss the specific practice of the maritime power strategy at the local and regional levels. Fifth, method innovation, such as designing the general situation indicator system of land and sea economic integration and the integration situation indicator system of various subsystems within it, and listing the measurement methods of key indicators. In August 2012, Professor Xia Fei led the academic team to apply for the approval of the major project of the National Social Science Foundation of China, "Research on the Evolution of China-ASEAN Economic and Trade Pattern and the Construction of China's Security Strategy in the South China Sea in the Next Decade" (12&ZD041), which follows the relevant spirit of "economic diplomacy" of national leaders and strives to upgrade China-ASEAN economic and trade relations and influence and promote the security and stability of the situation in the South China Sea by further deepening China-ASEAN economic and trade cooperation. The project has published a series of books by China Social Sciences Press, among which "Research on the Integration of Land-Sea Economy in the South China Sea" is a book with a new system created by Professor Xia Fei and his team. Since ancient times, the history of human civilization has been inextricably linked to the vast ocean, and 2,500 years ago, the ancient Greek oceanoist Divestoke said: "Whoever controls the ocean controls everything." "In the 21st century, mankind has entered the century of the ocean. Let us seize the opportunity to jointly study, develop and protect the ocean, promote the "Ocean Dream" and build the great "Chinese Dream" together. is the order.
