The 2015 International Big Data Industry Expo and the Global Summit on the Era of Big Data were held from May 26 to 29 in Guiyang. At a time when the concept of big data has taken root in people's hearts, elites from all walks of life have extensively launched "brainstorming" through the Guiyang Digital Expo, an international platform, which is conducive to the whole society to establish a deeper understanding of big data, making it an important boost to China's economic transformation and development.

After three industrial revolutions, including the application of the steam engine, large-scale production, and electronic information technology, the global economic development model is entering the fourth industrial revolution based on the information-physical fusion system (CPS), and marked by a high degree of digitization, networking, and automation of production, the so-called "Industry 4.0" era. The so-called "Industry 4.0" era. Since the concept was put forward, it has been widely emphasized around the world. Global industry into the "Industry 4.0" era, is in the Internet after the full development of the road of necessity, through the "Internet +" mode, more and more emerging industries have been developed, more and more traditional industries have been given a new life. At present, China's various industries for the "Internet +" mode of operation are actively involved, the state will also be an important way to stabilize economic growth and policy support. In this process, the use of big data will make the "Internet +" receive twice the result with half the effort.

The information processing mode of big data, whether it is for the government's economic management and control or business decision-making, is an important tool, which allows the government and enterprises to build up a stronger insight into the market information and decision-making power. As a simple example, taxi software, which has appeared in many cities since last year, utilizes a big data model to enable a more precise match between supply and demand for cabs, thus demonstrating a strong market life and shaking up the traditional cab operation model. Although there are still some opposing views between the government and the private sector on this novel cab service, this example vividly illustrates that big data, when utilized well, can not only bring new life to the industry, but also provide a new impetus to economic growth. It cannot be ignored that government departments in some cities are currently taking a severely restrictive countermeasure against the new cab industry in the form of Uber and other special cars, which, in addition to demonstrating the inertia of government departments in suppressing market innovations by administrative means, also shows that they lack a deep understanding of the market changes brought about by big data, and are unable to adapt to them well.

Big data will also play an important role in boosting domestic demand. In the process of China's economic transformation, although the government launched a lot of preferential policies, but the domestic demand has not been active, dragging the leg of the transformation, so that the promotion of stable growth has to still rely on investment expansion and monetary expansion. In fact, China's consumer market is far from saturated, only due to information asymmetry, the distance between the production of enterprises and consumer demand, so that more and more consumers because the domestic market can not meet the turn to buy overseas goods, so that the loss of domestic purchasing power in the country outside the door. A laughable example is that during the Spring Festival this year, many Chinese people traveling to Japan are keen to use the performance of the more comfortable toilet seat in Japan to buy, but later rumors are that this toilet seat is a domestic enterprise exported to Japan, just due to the market information is not open, which led to the "export to domestic sales" of this kind of The thing happened. If big data is more widely used, through the analysis of the user evaluation of big data mining, enterprises will be able to more targeted to improve the user experience, enterprise products and market demand can be realized "seamless docking", so as to effectively stimulate domestic demand.

The use of big data technology in China has just begun, both business and government are still exploring. In the future socio-economic development, China must seize the new opportunities brought by the big data era, so as to promote China to successfully realize the near-term goal of steady economic growth, improve quality and efficiency, and the long-term goal of building a moderately prosperous society in all aspects. Whoever occupies the windfall of big data will be able to grasp the "golden key" for future development. The Guiyang Digital Expo is an important opportunity to promote the popularization and promotion of big data technology in China, and to establish a new mode of thinking and economic regulation in line with the "Industry 4.0" era.

To make big data popular and a new driving force for China's economic growth, it is especially important to change the mindset of government departments. From the current situation, the government for the big data technology spawned by the new mode of operation can not be well adapted, so that often in order to maintain the interests of traditional industries and the industrial changes brought about by big data technology to suppress. Both companies and governments must take the initiative to adapt to the opportunities and challenges of the big data era in order to seize the opportunities for development in the future.
