The status of industrial pillars
According to the statistics of the Ministry of Industry and Information Technology, in 2011, the added value and investment growth of electronic information manufacturing enterprises above designated size were higher than the industrial average of 2.0 and nearly 20 percentage points respectively. Industry revenue and profits accounted for 8.9% and 6.1% of the country's industrial share respectively. The leading and pillar role of the electronics manufacturing industry in the overall industry is increasingly prominent.
In 2011, China's electronic information industry realized sales revenue of 9.3 trillion yuan, an increase of more than 20%; among them, the manufacturing industry above designated size achieved a revenue of 7490.9 billion yuan, a year-on-year increase of 17.1%; the software industry realized a revenue of 1,846.8 billion yuan (Express data). The previous year increased 35.9%. Electronic information manufacturing industry above designated size realized sales value of 7544.5 billion yuan, a year-on-year increase of 21.1%.
In 2011, electronic information manufacturing industry above designated size achieved a total profit of 330 billion yuan, a year-on-year increase of 16.8%. The industry's sales margin was 4.4%, which was basically the same as in 2010; the profit for the six months of the year was declining and the fluctuation was more obvious.
Increased penetration of major products
As of the end of 2011, China's mobile phone penetration rate reached 73.6 units/hundred, up 9.2 units/hundred more than in 2010; 3G network penetration rate reached 13.0%, which was 7.5 percentage points higher than that in 2010. China’s Internet penetration rate has reached 38.3%, which is 4 percentage points higher than the previous year. Among them, mobile internet users account for 69.4% of the total number of Internet users, which is 3.2% higher than the previous year. The number of color TV sets and computers owned by urban residents exceeded 135 units/hundred and 70 units/100, which were both higher than the previous year.
In terms of import and export, in 2011, the growth rate of the import and export of electronic information products was high and low. The total import and export volume reached 1,129.23 billion U.S. dollars, an increase of 11.5% year-on-year, accounting for 31% of the country's total foreign trade volume. The top three export products were: notebook computer 105.88 billion US dollars, an increase of 11.1%; mobile phone 62.76 billion US dollars, an increase of 34.3%; integrated circuits 32.57 billion US dollars, an increase of 11.4%.
What is Industrial DTU? Industrial DTU characteristics and application field analysis
What is DTU?
A Data Transfer unit (DTU) is a wireless terminal device that converts serial port data into IP data or IP data into serial port data over a wireless communication network.
Second, industrial DTU characteristics?
