The development of wire and cable industry promotes the development of power transmission and distribution, power transmission and other industries. With the development of China's electric power, data communication, urban rail transit and other industries, the demand for wire and cable products has increased, and the scale of the industry has been promoted. Statistics from the National Bureau of Statistics show that by 2017, China's wire and cable industry has reached 4034 Enterprises above the scale, and the number of enterprises has been reduced by 30 compared with 2016 due to the influence of the state's adjustment of excess capacity. However, from the overall scale of the industry, the overall fluctuation of sales revenue of China's wire and cable industry rose in 2011-2017, with an average compound annual growth rate of 4.02%. By 2017, the industry's sales revenue was 135.304 billion yuan, down 2.95% from the same period last year. With the adjustment of China's wire and cable industry entering a period of deepening development, the elimination of its excess and inferior capacity will have a certain impact on the overall market size of the industry. However, the products gradually change from power cables to special cables, and the sales revenue of China's wire and cable industry will continue to be small in 2018, thanks to the development of domestic related industries and the development strategy of the whole area. The increase was more than 140 billion yuan

        Wire and cable industry products are mainly divided into power cables, electrical equipment cables, winding cables, bare cables and communication cables. Because of the wide range of application of power cables, the income scale of this product accounts for a large proportion. In 2017, the revenue scale of power cable products reached 482.766 billion yuan, a decrease of 2.35 percentage points compared with the previous year. Influenced by the decline in the total scale of the industry, the scale of each sub-area has declined, with the largest proportion of decline in telecommunication cables reaching 3.7%. From the point of view of subdivision products, power cable is still an important field in the industry. In 2017, the output of power cable reached 49.336 million kilometers. In that year, the output of communication cable was about 55 million pairs of kilometers. In 2017, the annual output value of electric equipment cable reached 316.39 billion yuan.

         From the amount of import and export, although the export quantity of wire and cable in China is increasing continuously, compared with the import unit price, the export unit price of wire and cable is less than 100 million US dollars/10,000 tons on average, while the import unit price is about 200 million US dollars/10,000 tons. It can be seen that, although the export capacity of China's wire and cable is constantly improving, the value added of the overall product is lower than that of imported products.

        In recent years, with the improvement of our country's wire and cable production capacity and the increasing number of products exported, the development of our industry has been showing a trade surplus. The trade surplus of domestic wire and cable industry has been over 14 billion US dollars from 2014 to 2017, and the surplus is large. From 2018 to October, the trade surplus of wire and cable reached 12.96 billion US dollars. China's manufacturing industry has experienced the promotion of restructuring and capacity removal, and the wire and cable industry has been more standardized development. It is expected that in 2019, the acquisition, merger and adequacy of China's wire and cable production enterprises will increase, which will promote the continuous improvement of the concentration of the industry, and also promote the transformation and upgrading of the domestic wire and cable industry.
