According to the National Association of Industry and Commerce Stone Industry Chamber of Commerce, China's stone raw material production has now reached the world's No. 1, the processing capacity of the world's first, foreign trade exports in the world. The overall development of the stone industry in China is in a good situation. While maintaining a steady state, it is also tending to rise. It is also a new year in exports. Nowadays, China has not only ranked first in the world in terms of raw materials and production of stone materials, but has also surpassed Italy in the world in terms of processing.
Product structure changes qualitatively
After nearly two decades of development. China's stone production and supply structure and export trade structure have undergone fundamental changes. It is reported that at present, there are nearly 1,000 advanced stone production lines in China. These advanced production lines are the main factors directly leading to the upgrading of the stone industry structure in China. From the raw material, that is, the export of block materials to the absolute advantage of plate and finished materials, the qualitative change process not only reflects the current changes in China's industrial structure and trade structure, but also more prominently reflects the current production of stone industry in China. , improve the level of processing technology and product quality. In the current structure of stone export trade, the export of blocks accounted for less than 10%. It shows that the export structure of China's stone is moving toward optimization. If we add stones such as stone sculptures, the stone exports in China are far more than 3 billion US dollars.
With China's reform and opening up, China's stone industry has also ushered in a period of rapid development. The development of China's economy has increased the demand for stone materials throughout the society. Especially in the past decade, the accelerating development of the construction industry, real estate industry, and transportation industry has directly stimulated the consumption demand of the stone industry in China. The Chinese stone industry has ushered in a booming historical best period. Reshuffle in the industry has shown signs of being in the historical process of industrial development. For quite a while, due to unreasonable industrial structure and disorderly market competition, the Chinese stone industry could not extricate itself from the low cost of quality, directly leading to China's stone faces an unprecedented embarrassing situation in the international market competition. "Apart from the price, what else can I have?" At the International Stone Fair, some domestic stone merchants often laugh at themselves. The continuous decline in stone prices also fell below the EU’s reasonable level of prices. Therefore, a large number of importers of stone-requiring countries flew directly to large and small domestic stone processing plants, directly bargaining with their prices, and finally with extremely high prices. The low price is fully loaded.
In China's vast land, rich stone resources are not inexhaustible. The inefficiency of stone production and processing has caused serious waste of resources and serious environmental pollution problems. Behind the disorderly competition is a serious lack of industry responsibilities. The direct result of the vicious circle has led to an increase in the profit margin of the industry that is lower than the increase in production and sales. It has also caused the Chinese stone industry market space to face severe pressure from international stone brands, and enterprises have become increasingly difficult to survive. The continuous development of China's stone industry is undergoing a test, and China's stone industry is in urgent need of industrial structure optimization and brand upgrading. Fortunately, some companies can clearly realize this. At the end of the last century, in the face of increasingly severe international and domestic competition and the strong growth of the international market, some companies such as Fujian Shishi, Shanghai Tower Star, Guangdong Conley and Global, Shandong Yuze and Yutong, etc., have first stepped up international cooperation in science and technology and introduced foreign countries. The advanced machinery and equipment or learn from foreign advanced technologies and implement sustainable development strategies: from the original pit mining, blasting process transformation to step mining, wire sawing and other machinery cutting advanced technology; eliminate backward production methods, accelerate the construction of modern stone enterprises, Strengthen the market competitiveness of enterprise products and improve enterprise management. After several years of development, it took the lead in becoming an industrial group with modern awareness in the stone processing industry in China, and the pattern of industry reshuffle gradually emerged. Nowadays, China's stone industry structure has entered the "multi-stone" era from the "Three Stones" era. The stone industry has developed into a comprehensive diversified industry integrating granite, marble, artificial stone, stone carving, garden stone, cultural stone, stone machinery, abrasive tools, and diamond tools.
The development of the international market shows that only by strengthening the brand awareness of the stone, and strengthening and improving the technology, development, design, and manufacturing of product processing, can the added value of the products be improved; only by increasing the quality of products and investing in marketing planning and promotion can the company's visibility be improved. And the overall competitiveness of the industry. Only by enhancing the brand awareness of the entire stone industry in China and adapting to the brand needs of the market can the entire industry develop healthily and sustainably, and it will be able to cope with the increasingly severe domestic and international market competition.
