A large number of heavy industries with an unprecedented investment scale are forming a new industrial cluster in the PRD. The so-called industrial agglomeration refers to a number of similar enterprises that produce certain products within an appropriate large area, and the upstream and downstream enterprises that are equipped with these enterprises and the related service industries are densely clustered together and divided into horizontal agglomeration and Vertical gathering. As its name implies, horizontal agglomeration refers to the spatial concentration of enterprises of the same type and different scales. Vertical agglomeration is often carried out in one area by one or two large leading enterprises and a series of production and service facilities have been established around them Small and medium-sized enterprise cluster, and formed the upstream and downstream, prenatal, birth, post-natal related to the industrial chain. Although the agglomeration of industries in the Pearl River Delta is at the forefront of the whole country, it also exposes many drawbacks. Among them, the lack of vertical agglomeration, the lack of vertical correlation and the incomplete industrial chain are the problems most in need of solution. Encounter environmental bottlenecks The leather industry in Foshan Nanhai Luo Village enjoys a good reputation, but the pollution of water and air caused by heavy metals and waste gas generated during the production process is very serious. Although most of the tanneries have taken certain measures, the discharge of waste water is still difficult to achieve. In accordance with the environmental protection requirements of the state and Guangdong Province and the long-term development of tannery industry, Luocun required that leather enterprises should increase their investment in sewage treatment equipment and take measures to forcefully close, stop, and coordinate the enterprises that fail to meet environmental standards. However, as a result, new problems have emerged. As most of the local leather enterprises are small-scale producers, it is simply impossible to take the cost of high-cost environmental protection equipment and only relocate, shut down or switch to other products. After some control, there is little left in Luocun Tannery. Even the base number can not be guaranteed, let's talk about industrial agglomeration? The ultimate goal of industrial agglomeration is to continue the development, which is actually in line with the purpose of circular economy. At the beginning of this year, the business failures in the Pearl River Delta made an uproar at a time. Although the closure and relocation of enterprises only reflected some disadvantages of the industrial agglomeration in the Pearl River Delta, First, for now, the industrial agglomeration in the Pearl River Delta still stays in the labor-intensive, energy-intensive, low-tech and heavily polluting traditional industries. Second, the government does not guide the planning of industrial agglomeration. As the industries in the Pearl River Delta converge on the road of market-driven development, most of them are spontaneous agglomeration and development. The planning of industrial planning and industrial chain support is clearly inadequate, resulting in a large number of industries being isomorphic with serious duplication. Third, the "head" and "tail" of the enterprises in the Pearl River Delta are all outside. In the strict sense, they can only be considered as factories or production workshops. Therefore, industrial agglomeration only stays in the process of production and processing and the industrial support is inadequate, which severely restricts the exertion of cluster superiority . Many industrial parks known as industrial agglomerations lag behind in their planning and construction of infrastructure facilities. Facilities such as roads, communications, drainage and sewerage are not well-matched and seriously affect the intensive use of land. Environmental pollution is more serious and not conducive to the sustainable economic and social development. Fourth, the vast majority of the Pearl River Delta industrial agglomeration is a small business. These enterprises are subject to the scale and cost of production constraints, the general lack of capacity for independent innovation, industrial support is not perfect, environmental awareness and protection of poor. Vertical agglomeration to be strengthened Industrial agglomeration is a good thing in itself, which is conducive to the formation of a large-scale effect and drives the good operation of the entire industrial chain. However, the agglomeration of the Pearl River Delta industry is still stuck in the primary division of labor stage, which is the horizontal agglomeration mentioned earlier. This kind of agglomeration is only the concentration of industries in space and does not take into account the organic integration. It is easy to produce problems such as the low level of specialized division of labor, the weak links between the upstream and downstream industries, and the short industrial chain. In fact, most of these are just the horizontal agglomerations mentioned above. Such a trend of development is not conducive to the industrial scale and intensification but will only result in more redundant construction And waste of resources, contrary to the original intention of industrial agglomeration. The vertical agglomeration is different. It requires the agglomeration areas to concentrate their limited resources in a few areas for further development. Some large enterprises are appropriately developed in order to divert the division of labor to deeper development, that is, the "leading enterprises" effect. Some prominent industries The park is often used in this mode. Guangzhou Huadu automobile industry cluster is a good example. In a few short years, Huadu almost started from scratch. With the industrial restructuring of Guangzhou and the strategy of building "Beiyou" in industrial satellite cities, a modern integrated auto city rapidly emerged as one of the most competitive international automobiles in southern China city. All the successful automobile cities in the world have a world-famous car factory, Huadu is no exception, which is the main reason for the success of its automotive industry: the Aeolus car settled in Huadu Motor City, the first phase of hundreds of dumping land Soon to be more than 40 plants near the factory set up all over the world aimed at supporting the Nissan Auto Parts Factory a robbery; R & D center settled, but also makes Huadu Motor City officials and developers could not suppress the smile, Matthew Effect in the Automotive Industry: The stronger the supporting capabilities, the more attractive auto parts manufacturers. As a result, a complete automotive industry chain formed. The enthusiasm of private enterprises to expand Despite the soft underbelly of the industrial agglomeration in the Pearl River Delta, the recent dustfall of a large number of heavy industry projects has provided new ideas for industrial agglomeration. In particular, the strong private capital in the Pearl River Delta has also injected fresh blood into the industrial agglomeration in the PRD. Dongguan fashion, the South China Sea aluminum, Jiangmen's "microphone", Zhongshan lights ... ... as long as people who know about the Pearl River Delta will be able to say these local characteristics. It is the industrial agglomeration, the original fragmented private enterprises through the "vertical and horizontal" string together to form a scale effect. According to statistics, of the 404 established towns in the Pearl River Delta, more than 100 are specialized towns characterized by industrial clusters. These include Foshan, Zhongshan and Dongguan, which are mainly concentrated in the textile and clothing industries. They also include Foshan, Chaozhou , Yunfu ceramics and building materials industry-based gathering area. Together with the professional township enterprises, the Pearl River Delta is being built into the country's largest industrial cluster. In fact, the fiery industrial agglomeration actually has the same advantages as the economic planning of the headquarters promoted by major cities in the PRD. The participation of a large number of private-owned enterprises can not only bring together the advantages of small and medium-sized enterprises, establish a complete industrial chain, and form a large-scale operation, but also make up for the disadvantages of individual private-owned capital resources. In recent years, the industrial transfer industrial park in the Pearl River Delta has been vigorously built up. In fact, the starting point is to promote industrial agglomeration and form a "gathering ring." However, the actual operation lacks a clear positioning and planning. The fundamental, but also lies in the lack of vertical extension of industrial agglomeration.
