The "siphon" in the Pearl River Delta is too fierce, and the "non-pearl" five measures can be effectively solved.

The reform and opening-up policy has made the economy of Guangdong Pearl River Delta grow rapidly, and made the province's manpower and material resources gather in the Pearl River Delta. Matthew effect has further strengthened the Pearl River Delta's "siphon" ability to the western, eastern and northern mountainous areas of Guangdong, and aggravated the imbalance of regional development.

1 Improve the construction of supporting infrastructure.

Increase financial investment in infrastructure in eastern and western Guangdong. For education, medical care, transportation, communication, environmental protection, community and other infrastructure construction, provincial finance should increase policy tilt, set up special funds, and gradually increase investment in infrastructure in backward areas. According to the strategic requirements of "regional integration", the provincial government will coordinate and vigorously promote the modern transportation system and major infrastructure construction of regional integration, promote the construction of a large transportation system, and quickly integrate Guangdong, East and West into the Greater Bay Area transportation circle. Strengthen the network system construction of resources, energy, environmental protection, electric power and information, improve the medical and social security system, increase investment in culture and education, strengthen the basic skills training of workers, vigorously develop vocational and technical colleges and scientific research institutions according to the needs of industrial transfer, cultivate high-quality professional and technical personnel, improve the business and investment environment in eastern, northern and western Guangdong, change ideas, improve administrative efficiency, enhance the awareness of the rule of law and enhance market competitiveness.

2. Improve the guarantee mechanism of talents and human resources.

People are not only producers, but also consumers. Talent and manpower are both important factors to promote economic growth. Therefore, how to attract and retain talents and manpower in backward areas and improve the guarantee mechanism of talents and manpower are important measures to ensure economic development. The key is to take the introduction of urgently needed talents and the retention and cultivation of local talents as long-term goals and important talent strategies. Actively promote the Industry-University-Research combination mechanism of talent exchange and interaction among enterprises, universities and scientific research institutions; Establish an incentive mechanism and management model that is conducive to promoting the growth and development of scientific and technological personnel in enterprises, vigorously promote the innovative management of human resources based on talents, respect and cherish talents, and create a working platform for the development and growth of scientific and technological personnel. Excellent life, education, work, humanities, transportation and medical care are effective means to retain talents. Through industrial transformation and upgrading, we will promote the optimization of labor structure, introduce middle and senior skilled talents, guide the transfer of labor-intensive industries and ordinary labor in the Pearl River Delta to the eastern and western wings and northern mountainous areas through industrial transfer, and at the same time promote the dual transfer of manpower and talents, promote the optimization and upgrading of industrial structure in eastern and western Guangdong, and promote local economic development.

3 adjust the regional industrial structure

In order to realize the coordinated development of regional economy in the whole province, in 2008, the Guangdong provincial government issued a "double transfer" strategy. The goal is to transfer the labor-intensive industries in the Pearl River Delta to the eastern and western wings and mountainous areas of northern Guangdong, and the labor force in the eastern and western wings and mountainous areas of northern Guangdong to the local secondary and tertiary industries. Take the construction of industrial transfer industrial parks in the eastern and western wings of Guangdong and the northern mountainous areas as an important highlight, conscientiously implement the provincial industrial transfer policy, build industrial parks, actively promote local infrastructure and project construction, and focus on planning 1-2 large-scale industrial transfer parks with strong radiation-driven ability. Therefore, Guangdong, North and West should optimize the industrial structure, vigorously develop the secondary and tertiary industries, promote the industrialization and modernization of the eastern and western wings and the northern mountainous areas, form a reasonable regional industrial layout, undertake intensive industries transferred from the Pearl River Delta, form an industrial transfer park network system with complementary advantages with the Pearl River Delta, and realize the coordinated and balanced development goal of the same distribution of industries. The same market, the same transportation management, the same power network, the same information sharing and the same environmental protection management. Accelerate the pace of "double transfer", strengthen the training service of human resources before the transfer of labor force and employment, and promote the transfer of labor force from eastern and western Guangdong to industrial parks and local employment. Under the premise of following the economic laws, enterprises in the Pearl River Delta region are encouraged to transfer intensive production links to the eastern and western regions of Guangdong under the guidance of the government, market-oriented and enterprises-oriented, so as to promote the coordinated and cooperative development of the Pearl River Delta region and the eastern and western regions of Guangdong. At the same time, the eastern and western regions of Guangdong should combine local advantageous industries, support the cultivation of leading enterprises with local characteristics, promote the joint development of newly introduced projects and local original industries, stimulate the development potential of local industries, lead industrial construction to a deeper level and realize high-level transfer. [20] Therefore, it is necessary to organically combine industrial transfer with regional coordinated development, guide the orderly transfer of industries from the overall strategy of regional coordinated development, and rely on industrial transfer to promote regional coordinated development.

4. Improve the coordination mechanism of public finance for regional development.

Realizing the regional public service balance in Guangdong Province is an important way to solve the unbalanced development, and the key lies in narrowing the economic development gap between regions. In a certain period of time, limited by the strength of local economic development in eastern Guangdong and northern Guangdong, it is difficult to rely on local governments to realize the leap-forward development of public services in a short time. Objectively speaking, in order to speed up the pace of local economic development, increase the public finance revenue of local governments, and improve the level of public services in eastern, western and eastern Guangdong, it is necessary for provincial finance to make appropriate public transfer payments in the short term, especially for some major infrastructure projects, which need special support from provincial finance. But at the same time, it is also necessary to formulate a scientific and reasonable implementation plan for equalization of public services, clarify the division of administrative power and financial power, reflect the benefit scope of basic public services in the distribution of administrative power, and realize the unity of rights, responsibilities and interests. Therefore, provincial governments should ensure that the benefit scope of basic public services is consistent with the government's jurisdiction through effective authorization, and encourage local governments to provide and guarantee basic public services within their jurisdiction through policy support. Balancing regional financial resources through fiscal transfer payment system plays an important role in balancing regional public services. The fiscal policy for the coordinated development of regional economy in Guangdong Province should be: on the basis of giving consideration to fairness and efficiency, adjust the allocation of resources between regions mainly through government transfer payment, government investment and tax incentives, so as to maximize the overall efficiency. The policy of coordinating regional development must be implemented, and it cannot stay at the policy level of "talking but not doing".

Give full play to Greater Bay Area's radiation effect on western Guangdong, eastern Guangdong and northern mountainous areas.

In 20 17, the Fifth National People's Congress put forward the blueprint for the urban agglomeration planning of Guangdong, Hong Kong and Macao to deepen cooperation between the Pearl River Delta and Hong Kong and Macao, and the Pearl River Delta ushered in a new round of development opportunities. However, while actively promoting the construction of Guangdong-Hong Kong-Macao Greater Bay Area, in order to avoid the "siphon effect" of Guangdong-Hong Kong-Macao Greater Bay Area on the backward eastern, western and eastern regions of Guangdong, the government should make overall planning, make the eastern, western and eastern regions of Guangdong actively integrate into the construction of Guangdong-Hong Kong-Macao Greater Bay Area, give full play to its own advantages, and make arrangements for industrial transfer and double transfer of Greater Bay Area subprojects and subprojects to the eastern, western and eastern regions of Guangdong, and integrate the eastern and western regions of Guangdong into the development and construction of Greater Bay Area through double transfer. According to the "center-periphery" model of Guangdong's economic development, the farthest distance that the scale economic benefit brought by Greater Bay Area agglomeration is greater than the transportation cost can be defined as the radiation range of the central area, while the eastern, western wings and northern mountainous areas are all within the radiation range of the Pearl River Delta. With the gradual improvement of infrastructure in eastern and western Guangdong and the full opening of high-speed rail lines in the province, the Pearl River Delta urban agglomeration is connected with other cities in Guangdong Province by roads and railways. The cost of personnel exchanges and material transportation has been reduced, and the manufacturing and service centers in the core area of the Pearl River Delta have promoted the development of the eastern and western wings and the northern mountainous areas within the radiation range. The government can establish a regional cooperation and coordination mechanism through industrial policy and financial coordination mechanism to avoid the "siphon effect" of the Pearl River Delta in the construction of Greater Bay Area and give full play to its "radiation effect".
