Read the material and complete the following questions. Material 1 "enclave economy" refers to the break between the governments of developed areas (flying areas) and underdeveloped areas (flying areas).

(1) Sediment deposition in the Yellow River (flowing water deposition).

(2) Abundant land resources. Capital, technology and management experience.

(3) Coastal distribution. * * * Use of infrastructure; Reduce production costs and obtain agglomeration benefits; Strengthen communication and cooperation.

(4) Marine chemical industry, marine new energy, coastal oil, port logistics, etc. Adjust the industrial structure and develop high technology; Effectively strengthen ecological construction; Strengthen environmental protection; Save the use of resources; Develop circular economy, etc.

(1) The newly-added land in the Yellow River Delta refers to the continuous expansion of the delta area, which is formed because the Yellow River carries a large amount of sediment in the estuary. (2) The Yellow River Delta is constantly adding land, which is rich in land resources, providing a broad space for economic development and becoming the most important advantage in developing "enclave economy"; Developed regions can provide the region with capital, technology and advanced management experience.

(3) As can be seen from the figure, the industrial clusters in Shandong Peninsula are mainly distributed in coastal areas, which can expand production scale, reduce production costs and improve agglomeration efficiency.

(4) Reading the map carefully, it is not difficult to see that the dominant industries in the blue economic zone are mainly marine chemicals, marine transportation, marine new energy and so on. The development measures can be analyzed from the aspects of energy saving, environmental protection and the development of high technology.
