In these regional development strategic plans, many of the key issues involved the petroleum and chemical industries. The industry is accelerating its development and optimizing opportunities for development. To highlight the intensive development of the petrochemical industry, it is necessary to scientifically develop petrochemical parks. In the future, chemical plants cannot be built in places without parks. Therefore, the layout of the park determines the layout of the petrochemical industry in this region. The petroleum and chemical industries should take advantage of the strategic economic development of the regional economy, combine local resources, environmental conditions, and industrial economic foundations to define the location of the park, highlight their respective characteristics, and form core competitiveness.
For example, in the "Outline of the Development Plan for the Economic Zone on the West Coast of the Taiwan Straits (Revision)", Fujian Quzhou Gulei Economic Development Zone and Meizhou Bay Petrochemical Base are listed as the Hercynian petrochemical base. As the Gulei District has determined a new functional orientation, it will continue to attract petrochemical upstream industries, especially oil-head projects. Recently, the Taiwan Petrochemical Association decided to build Gu Lei Taiwan Petrochemical Industrial Park. According to the vision of Kang Xishun, director of the Gure Development Management Committee, the Gulei District will use five years to realize the construction of oil and ethylene and downstream auxiliary projects, and strive to achieve an annual output value of RMB 300 billion at the end of the “Twelfth Five-year Plan†period.
The “Regulations for the Adjustment and Revitalization of the Petrochemical Industry in Gansu Province†clearly stated that after three years of adjustment and revitalization, the construction of the Gansu Petrochemical Industrial Park will take shape. This will prompt the province's petrochemical industry to get rid of the disadvantages of low industrial linkage, relatively fragmented layout, and low technical level.
At the same time, Liaoning proposed combining northeast revitalization with coastal openness and building petrochemical industrial clusters and fine chemical industrial clusters; Jiangsu proposed that coastal areas should rely on deepwater port resources, combined with local resources to develop salt chemicals, agrochemicals, etc.; Shanxi proposed to speed up construction New energy industry base.
In the planning of regional chemical industry, it is necessary to consider the combination of industrial chain and industrial agglomeration to change the current number of chemical industry parks, the distribution of which is scattered, the characteristics are not prominent, and the resource conditions are not implemented. At the same time, the development of the park should be characterized by the regional conditions and the distribution of productivity. Yang Ting, deputy director of the China Chemical Industry Development Center, proposed the following types of park development.
Refinery integration park. In regions with resource conditions and industrial bases, it is recommended that refineries, crackers, and aromatics plants be brought loosely and tightly through joint, merger, and reorganization so that the synergies of refining and production integration can be fully realized.
Coal Chemical Industry Park. It is recommended that coal-power generation-chemical integration be used to build large-scale industrial clusters and cultivate world-class coal chemical large-scale industries. At the same time, the construction of coal chemical parks must also consider more factors such as local water resources and the environment.
Fine Chemical Park. At present, the number of fine chemical parks in various parts of the country, especially in the coastal areas, is relatively large and the layout is relatively decentralized. It is necessary to increase the concentration of the enterprises. It is recommended to accelerate the pace of large-scale petrochemical industries entering the fine chemical industry and to make the products serialized and diversified.
Chemical New Material Park. The chemical new material industry has a lot of room for development. New material industrial parks have been built in Jiaxing, Zhejiang, Jinchang, Gansu, and Dalian, Liaoning. New material parks need to increase scientific research and development efforts, prompt enterprises to accelerate the formation of independent intellectual property rights, extend the industrial chain, and increase the added value.
It`s useful for any DIY-er to know how things around the home operate. Understanding the different parts that work together to make a door handle and lock work, can help you fix minor problems on your own.
Regional Economic Revitalization Plan Promotes Scientific Development of Petrochemical Industrial Park
Premier Wen Jiabao pointed out in his "Government Work Report" in 2010 that it is necessary to continue to deepen the development of the western region, fully rejuvenate the old industrial bases in the northeast, vigorously promote the rise of the central region, and actively support the development of the eastern region. Since the financial crisis, China has incorporated key regional development into its national development strategy. Last year, China approved 11 regional revitalization and development plans for the Pearl River Delta region, the economic zone on the west bank of the Taiwan Strait, the Guanzhong-Tianshui Economic Zone, and almost four years ago.
