China’s private investment growth rate of 34% in the first seven months of this year needs to eliminate hidden barriers.
At present, the macro economy is in a critical period of stabilization and stability. While various statistics show that positive factors in economic operations are increasing, more people are focusing on the sustainability of economic recovery. One of the big question marks. Is the private investment able to follow up in time? Zhang Ping, director of the National Development and Reform Commission, said in a report to the Standing Committee of the National People's Congress on the implementation of the national economic and social development plan this year. In the first seven months, the growth rate of urban fixed assets investment reached 32.9%, of which private investment growth rate reached 34. %.
According to the statistics of the State Administration for Industry and Commerce, as of the end of June, there were 6,923,500 private enterprises in the country, with a registered capital of 12.81 trillion yuan, up 5.31% and 9.11% respectively from the end of last year. The increase in the number of private enterprise registrations and registered capital confirms that private investment is picking up.
The flow and structure of private capital are changing. While private investment is gradually picking up, the flow and structure of private capital are also changing.
The coal char industry was once the main “output†and “inflow†of Shanxi's private capital. In the face of the international financial crisis and the integration policy of Shanxi's coal resources, many private capitals began to flow out.
Do not dry coal char, what? Li Qiuyi, who has been a "coal boss" for more than 10 years, found that the edible fungus market is almost blank in Shanxi, and the market space is huge. Therefore, Li Qiuyu invested another 180 million yuan, determined to build his own edible mushroom kingdom. In fact, the "coal boss" who thinks about this issue is not limited to Li Qiuyi. To this end, in July this year, Shanxi Province issued the "Opinions on Promoting Private Capital to Enter the Province's Encouragement Areas" to guide the flow of private capital.
According to statistics from the Taiyuan Center Sub-branch, from October last year to February this year, a total of 2.916 billion yuan of private capital was transferred from energy industries such as coal, coking, smelting and chemical industries to non-energy sources such as agriculture, education, real estate, tourism and finance. In addition to the decline in the total amount of private investment in the energy industry, the amount of other investments and their share have increased.
In Zhejiang and other places, more and more private capital is flowing to new energy industries such as photovoltaics. In May of this year, three new energy projects, including Longjing Technology, Longchi Curtain Wall and CIGS Solar, were signed in Hangzhou Economic and Technological Development Zone. Together with Tianyu Solar Energy, which has already settled in, the new energy project focusing on photovoltaic industry has become this. The key direction of industrial transformation in a development zone. In the past, Shangyu City, which is a pillar industry with electromechanical, chemical, printing and dyeing, has also been involved in or ready to enter the new energy industry.
This is not unrelated to Zhejiang Province's vigorous encouragement and guidance of social investment into the new energy industry. Relevant departments of Zhejiang Province encourage social funds to participate in the construction of new energy projects, and support enterprises to invest in new energy industry through various forms such as guarantees and venture capital.
There is still a need to eliminate hidden barriers and stimulate the vitality of private investment. In the exchanges with private entrepreneurs in Guangdong, there is a lack of investment opportunities.
In the central garbage collection processing base of Zhongshan City, the whole process is non-emission, pollution-free and odorless, and the technology and equipment are world-class. The core of this environmental protection processing base is a BOT waste incineration power plant project invested by the private enterprise Changqing Group with a total investment of 320 million yuan.
Yuan Furong, the person in charge of the project, said that the project handled more than 1,000 tons of garbage per day, accounting for about one-third of the total waste disposal in Zhongshan. The government pays a total of more than 20 million yuan in processing fees per year, which basically maintains the normal operation of the two units of the power plant. The basic investment is amortized annually in the generation income. Yuan Fuliang said that the waste incineration power plant is a good project for Changqing, a private enterprise. The government can open up to private enterprises and reflect the fairness of the government.
But at present, not every local private enterprise can enjoy such fair investment opportunities.
Statistics from Guangdong Province show that the current industry distribution of private enterprise investment is too concentrated, and 96.8% of individual industrial and commercial households and 76.4% of private enterprises are concentrated in manufacturing, wholesale and retail, accommodation and catering, transportation and residential services. Most of these industries tend to be saturated and the competition is fierce, which has inhibited the development of the private economy to a certain extent. If we can further relax market access and encourage private enterprises to develop into service industries and infrastructure, it will be more conducive to enhancing the enthusiasm of private enterprises.
It is mainly made of a material with high pyroelectric coefficient, such as lead zirconate titanate ceramics, lithium tantalate, triglyceride titanium sulfate, etc. to make the detection element with a size of 2*1mm. Install one or two detection elements in each detector, and connect the two detection elements in series with reverse polarity to suppress the interference caused by the rise of their own temperature. The detection element converts the detected and received infrared radiation into a weak voltage signal, which is amplified by the field effect tube installed in the probe and output outward. In order to improve the detection sensitivity of the detector and increase the detection distance, a Fresnel lens is generally installed in front of the detector. The lens is made of transparent plastic. The upper and lower parts of the lens are divided into several equal parts. It is a kind of lens with a special optical system. It can amplify the signal by more than 70 decibels in cooperation with the amplifying circuit, so that the movement of people within 20 meters can be measured.
The Fresnel lens uses the special optical principle of the lens to produce an alternating "blind zone" and "high-sensitivity zone" in front of the detector to improve its detection and reception sensitivity. When someone walks in front of the lens, the infrared rays emitted by the human body will alternate from the "blind area" to the "high sensitive area", so that the received infrared signal is input in the form of sudden strong and weak pulses, thereby strengthening its energy amplitude .
The central wavelength of infrared radiation radiated by the human body is 9~10--um, and the wavelength sensitivity of the detection element is almost stable in the range of 0.2~20--um. A window equipped with a filter lens is opened at the top of the sensor. The wavelength range of light that this filter can pass is 7~10--um, which is suitable for the detection of human infrared radiation, and other wavelengths of infrared rays are filtered. The sheet is absorbed, thus forming an infrared sensor specially used to detect human body radiation.
