From January to June 2014, China exported a total of 2.59 billion sets of bearings, earning 2.4 billion U.S. dollars, an increase of 14.23 percent and 6.92 percent over the same period of last year. From the perspective of export regions, Asia is still the major exporter of bearings in China, and foreign exchange earned accounted for the total amount of foreign exchange earned. 46.77, but the growth rate is a slight negative growth of -0.74; Europe is the second largest exporter of bearings in China, accounting for 26.75 of the total foreign exchange earnings, which is an increase of 16.4.

The Americas is the third major export area of ​​bearings in China. Foreign exchange earning accounted for 23.5 of the total foreign exchange earnings, which was a year-on-year increase of 13.03. From the perspective of foreign exchange earned through bearing exports, the demand for bearings in Asia was basically the same as that of the same period of last year, and the demand for bearings in Europe grew stronger. The increase in bearing demand is also a relatively good trend.

From a country point of view, the United States is still the country's largest exporter of bearing exports, with an export value of 360 million U.S. dollars, accounting for 15 percent of total foreign exchange earnings, a year-on-year increase of 15.5. It also shows from the side that there are signs of economic recovery in the United States and Europe.

When the hardware bearing industry was still immersed in the increase in revenue of 30 in 2010, it was faced with a crisis of sharply reduced revenue growth in 2011. This year's operating income growth rate may fall to 12. 2011, the pressure on the bearing industry will further increase, the growth rate of the bearing industry will be somewhat slower, it is worth bearing companies attach great importance to.

The survival, development, and innovation of the fittest will analyze the development information of the hardware bearing industry, and will continue to analyze the development of the situation in light of the company's own situation and make decisions for the development of the enterprise as soon as possible. China Metal Bearing Industry Association hopes that companies in the industry will attach great importance to the 12th five-year development plan for the country, each host industry and the bearing industry, and study the development direction of key products from the country's strategic emerging industries.

We attach great importance to the improvement of management levels, reduce غير مجاز مي باشدts through management, and enhance the competitiveness of enterprises. We should attach great importance to the development of the market and timely adjust the product structure in accordance with market development. We attach great importance to scientific research. While researching the upgrading of old products, we must not only develop new products based on the market in real time, but also develop and reserve some new products in the future in line with market development.

Looking for a way out in the crisis, the principle of survival of the fittest will begin in the bearing industry. The غير مجاز مي باشدt is too high and the competition is too strong. Some people pointed out that last year due to further intensified industry competition and rising raw material prices, unprecedented difficulties were encountered in the production and operation of hardware bearings. The orders for petroleum machinery bearing products for leading products have been substantially reduced, and the product structure has tended to be miniaturized. A large loss occurred throughout the year.

It has been said that in the first half of the year, due to the year-on-year increase in the prices of raw materials, steel, and purchased parts, the automotive industry’s market demand has declined, and thus the total profit of major companies has been relatively reduced.

From the prediction report of the bearing industry's future prospects, it is understood that the development of the hardware bearing industry does face some unfavorable development factors.

(1) The overall exchange rate of *** will show an upward trend, and the competitiveness of ordinary bearings and mid-end bearing products will be further weakened. The pressure on hardware bearing products will gradually increase, and the import of bearing products will also increase.

(B) It is expected that raw material prices and labor غير مجاز مي باشدts will show an upward trend in 2011, which will bring certain pressure on the company's غير مجاز مي باشدts. The fluctuations in the markets of automobiles, agricultural machinery, and household appliances will have a certain impact on the speed of development of the hardware bearing industry.

(3) Affected by the rapid and steady development of China's economy, international multinational hardware bearing companies have accelerated the pace of building and expanding factories in China, and the market competition in high-end and high-end bearings will be fiercer.

A hardware shaft company has disclosed annual reports, claiming that the company had a loss of 156 million yuan last year, a year-on-year decrease of 30.32; a loss of 0.72 yuan per share. According to the announcement, the company's stocks were suspended for one day on April 19, and special treatment for delisting risk warnings was implemented on April 20. The stock abbreviation was changed to ST West axis, and the company's stock price was limited to 5. The loss of hardware bearings made other bearings. The company began to worry about anxiety.

Afterwards, the hardware bearing unit also issued a semi-annual performance forecast on the evening of July 8. It is expected that the company will realize a net profit of 2.55 million yuan in the first half of the year, a year-on-year drop of 69. The crisis is full of misfortunes. In early 2011, it was still a hidden crisis. Now The child surfaced. Ears have gradually spread all kinds of unsatisfactory news.

In addition to focusing on quality and pursuing innovation, today's hardware lock companies must also devote their efforts to marketing strategies in order to be invincible in the market. To do a good job in corporate marketing, it is really necessary to rack its brains, to make it work, and to do full-scale marketing! Understand the market demand Marketing must have its own personality, use its own characteristics to create a demand to attract consumers; the other is to meet the customer's intrinsic needs in all directions, that is to say, the company must develop a natural, rich and colorful alternative. The products, in order to break through the conventional and aggressive marketing, excavate, guide, create and meet the market demand, in line with the personalized consumer tide of today's people seeking new, different, and change.

Companies must use marketing skills that compete with competitors to intentionally lead the market and consumer groups to grow in a direction that is beneficial to themselves, make potential markets a real market, and gradually widen their distance from competitors to make themselves more For the unique, in order to eventually reach the market, occupy the market, have a marketing purpose for a marketing idea. To satisfy personal requirements to the utmost, the so-called "customer is God", everything must start from the customer, and establish a good relationship with each customer to carry out the difference. After knowing the needs of customers, the greatest limit meets the individual needs of consumers. In the nature of marketing, consumers are completely self-centered when they purchase merchandise, and existing products can not meet the demand, they can put forward specific requirements to enterprises, and enterprises can customize the ideal products of consumers. With the king's product, the market competitiveness of the company is virtually enhanced.

In an increasingly competitive market, who's products can best meet the needs of customers, who will eventually win the market. Hardware locks companies can understand the changes in market demand in a timely manner, develop a natural marketing strategy, the company's market competitiveness has increased, the company's economic benefits will also rise, and further promote the expansion of the company's growth! The expansion of all these functions makes it an important component of the building and, at the same time, greatly enhances the market competitiveness of hardware locks. Whoever can grasp the market will be able to achieve success.
