According to the relevant management measures, the Yellow River Delta region will set up the Yellow River Delta industrial (equity) investment fund. At the same time, the region will also seek to establish rural commercial banks. The scope of the Yellow Triangle Economic Zone is based on the development plan of the Yellow River Delta Efficient Ecological Economic Zone. The Yellow Triangle Economic Zone mainly includes Dongying City, Binzhou City, Weifang City, Dezhou City, Zibo City and Yantai City in Shandong Province, with a total of *** 19 counties (cities, districts) and a land area of 26,500 square kilometers, accounting for about one-sixth of the total area of Shandong Province. The development planning of the Yellow River Delta mainly focuses on developing efficient ecological economy. The so-called high-efficiency ecological economy refers to an economical and intensive economic development model with typical ecosystem characteristics. In terms of industrial types, a circular economy industrial system composed of clean production enterprises is formed; In terms of industrial layout, an eco-industrial cluster consisting of several eco-industrial parks is formed; To realize no waste or less waste in the production process and realize the recycling of the production process is ultimately manifested in the efficient operation of the whole economic system and the coordinated development of economy, society and ecology. The main economic indicators in this area will increase rapidly. In 2008, the regional GDP was 475.6 billion yuan, which is expected to reach 930 billion yuan in 20 15 and150 billion yuan in 2020. The development planning of the Yellow River Delta will affect the layout framework of "four points", "four areas" and "one belt" in the Yellow River Delta region. "Four Points" refers to Dongying, Binzhou, Weifang Port and Laizhou Port, "Four Districts" refers to four port-facing industrial zones in Dongying, Binzhou, northern Weifang and Laizhou, and "One Belt" refers to the economic agglomeration zone on the south bank of Bohai Sea supported by four ports, with four port-facing industrial zones as the core and economic and technological development zones, characteristic industrial parks and high-efficiency ecological agriculture demonstration zones as the nodes. In April 2008, Shandong Province issued a policy. During the Eleventh Five-Year Plan period, Shandong will plan to invest about 654.38+0.5 trillion yuan in this area, accounting for about 20% of the total investment in the province. However, the plan reviewed and adopted by the State Council this time did not involve specific investment amount. 80 billion yuan Bohai Industrial Fund has been set up for the construction of Tianjin Binhai New Area, and a similar fund will be set up for the development of the Yellow River Delta. After the Pearl River Delta and Yangtze River Delta in the south become the regional centers of China's economic development, the Yellow River Delta in the north will also usher in the key development of trillions of funds.
