In 2013, China's high-tech industry experienced remarkable growth. The national technology contract turnover reached 746.9 billion yuan, with an annual increase of 16%. The main revenue of the national high-tech industry is expected to exceed 11 trillion yuan, rising by 10%. Additionally, the total revenue of 105 national high-tech zones is projected to surpass 19.5 trillion yuan, reflecting a growth of around 18%. There are nearly 60,000 high-tech enterprises operating effectively across the country, and among the 355 companies listed on the Growth Enterprise Market (GEM), 93% are high-tech firms. These figures were shared at the 2014 National Science and Technology Work Conference.
China is now actively participating in global innovation competitions. For years, it was often viewed as a manufacturing hub producing electronic devices for international brands. Many high-tech products lacked core technologies and struggled to compete globally. However, this trend has changed due to years of independent innovation and market experience.
In 2013, several Chinese high-tech companies made significant strides in the international arena. According to IDC and Gartner, Lenovo overtook HP to become the world’s largest PC supplier, marking its first time as the undisputed leader in the global PC industry. Tencent’s stock price nearly doubled in one year, reaching a market capitalization of $123 billion, close to Facebook’s $140 billion valuation. Meanwhile, Huawei signed a $700 million contract with TDC, Denmark’s largest telecom operator, to replace Ericsson’s equipment and services.
Beyond established players, emerging tech startups also began expanding internationally. Companies like 58.com, Qunar.com, and Tianxia Map went public in the U.S. and Hong Kong toward the end of 2013.
Chinese technological standards are also gaining global recognition. In 2013, China's fourth-generation mobile communication standard, TD-LTE, which is independently developed, entered commercial use. So far, 23 TD-LTE networks have been deployed in 18 countries worldwide. The TD-LTE Global Development Initiative (GTI) has brought together 80 operators and 63 industry partners, forming a strong platform for collaboration. This marks a matured industry chain for TD-LTE.
Experts in the communications field note that in the 1G era, China relied entirely on imported equipment. In the 2G era, it was just a passive participant. By the 3G era, China gained a seat at the table, but still depended on foreign standards like WCDMA and CDMA2000. However, in the 4G era, with TD-LTE becoming one of the two major global standards, China is now on equal footing and has achieved leapfrog development.
According to a PwC executive, Chinese tech companies are increasingly challenging global leaders and showing promising trends in telecommunications, mobile devices, and online services. While they once followed quickly, real innovation is now emerging.
The rapid growth of China's high-tech sector is supported by increased investment in science and technology and favorable policies. In 2013, total social R&D expenditure reached 1.18 trillion yuan, accounting for 2% of GDP, with more than 76% coming from enterprises. In 2012, tax deductions for R&D expenses exceeded 43 billion yuan, while high-tech enterprises saved 85 billion yuan in income tax, totaling 310.9 billion yuan over five years.
As key drivers of high-tech development, the 105 national high-tech zones implemented an innovation-driven strategy in 2013, significantly enhancing their independent innovation capabilities. Their total revenue is expected to exceed 19.5 trillion yuan. The national independent innovation demonstration zones continued to grow and became models for economic transformation. For example, Zhongguancun’s enterprises contributed over 25% to Beijing’s economic growth, while Zhangjiang and Wuhan’s zones reported revenues of 1068.1 billion and 465.2 billion yuan respectively in the first three quarters of 2013.
These achievements were made despite the global economic downturn, highlighting the effectiveness of policy support, improved innovation efficiency, and successful technology transfer and industrialization.
Ball Valve
Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.
Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.
