Major obstacles to entry into the industry

1.Technical barriers
    Special refrigeration equipment R & D, production process needs to be applied to knowledge of many discipline fields of fundamental physics, materials, mechanical, automation and control, etc., with high technical content; coupled with new application market continue to emerge, the product development to has relatively strong technical reserves as the basis, so as to shorten the development cycle, the rapid introduction of adapt to the market demand for new products, in order to occupy new market. This has raised the high demand for the technical accumulation of the manufacturer, and the new entrants in this industry also formed a higher technical threshold.
     The advantages of the company: the company in the domestic counterparts in the first with the international first-class enterprise cooperation, the introduction of foreign advanced technology, at the same time, industry technology and process is not rely on simple introduction can be achieved, need long time digestion absorption, secondary development to grasp. In addition, customer demand increasingly diversified and high standardization, we as an industry leading enterprises, with strong technical innovation and product promotion ability, can according to the market changes and customer needs to rapidly develop products meeting the market demand, this new entrants to constitute certain technical barriers.

2.Technological barriers
    Special refrigeration equipment is multiple components of system integration of the whole product, assembly, debugging, testing through in the whole production process, the need to have installed experience rich, master process know-how of mature craftsmen. More important, the use of special refrigeration equipment, the use of harsh environment, must be widely used in the product unique process, the new entrants with a higher technological barriers.
3.Talent barriers
   Special refrigeration equipment research and development, production of comprehensive technical requirements of manufacturers need to have areas of talent pool, such as special refrigeration system design, the design of automation control personnel, highly efficient heat exchange and heat exchanger design personnel, the whole system design personnel. The overall number of R & D personnel in the domestic related technology is relatively small, and the new entrants to obtain the relevant talents in all fields are quite difficult.. In addition to its aggregation, running in, the formation of team strength and the development of new products will also go through many years of practice. At the same time, some key technology positions also need to experience the skilled workers to do. Therefore, this industry has a high talent barriers to new entrants.
4.Qualification barriers
    In order to establish long-term cooperative relations with large and first-class enterprises, special refrigeration equipment manufacturers need to obtain the national industrial production license, but also through strict supplier qualification. Large, first-class enterprise for the recognition of the requirements of high, long time. For example, macro and company in Japan before the formal purchase, usually need to target supplier for a period of 2 years of products test and third party certification, special refrigeration equipment manufacturers only through the quality identification and project auditing, in order to become its suppliers. In order to ensure the quality and supply of the stability of the product, machine tool manufacturing, ship manufacturing and other enterprises will not easily change suppliers. This strict supplier qualification, as well as the formation of stable customer relationship based on long-term cooperation, the new entrants to the special refrigeration equipment industry constitutes a strong qualification barriers.
5.Customer loyalty barriers
   Special refrigeration equipment users mainly distributed in machinery manufacturing, shipbuilding, metallurgy field, over the field of units from the safety and reliability of often requires that the supplier has a strong product development capabilities, high level of detection, and good after-sale tracking service, so generally do not easily replaced has been used and stable quality, reliable products, will not give up easily with existing suppliers cooperation.

Favorable and unfavorable factors for the development of the industry
Favorable factor

1.Policy support
   Ordinary policies such as: cut even the abolition of tariffs and other trade barriers, improve business environment. The tax system and tax policy adjustment, including the implementation of increase and reduction of tax policy; in accordance with the principle of national treatment of foreign enterprises income tax, according to broaden the tax base and principles for reducing tax, reduce the tax burden of domestic enterprises, the abolition of foreign-invested enterprises preferential tax will make our country commercial central air conditioning enterprises obtain a fair competition environment.
Technical aspects of the policy such as: efficient, environmentally friendly, energy-efficient central air-conditioning host by government industry policy support. In December 1997, the State Science and Technology Commission promulgated the catalogue of national high and new technology products, the new high efficiency compressor and efficient refrigeration machine included, to encourage their development. 'in August 2001, the State General Administration of Customs released "China's high-tech products export directory", encourage the efficient refrigeration machine and Macao rasp refrigerator export.
Support of various policies will be very conducive to the development of the industry.
2.Capital market support
   With the domestic capital market for private enterprises gradually open, strength, development prospects, management more standardized, central air conditioning production enterprises to get listed opportunities, through financing, a lot of money, to lay the foundation for the further development. To get the support of the capital market, the industry will develop faster and better, improve enterprise strength.

Unfavorable factor

1.The impact of the economic cycle
  Central air conditioning products and real estate, medicine, textiles, iron and steel, petrochemical, electronic communications and other industries are closely related, China's central air-conditioning industry is nearly a decade of rapid development to a large extent thanks to the great development of the industry investment in fixed assets. Because of the industry investment in fixed assets is directly affected by the impact of the economic cycle, coupled with central air conditioning as a large mechanical products by the restriction of social consumption and investment ability, when the economic cycle fluctuations, central air-conditioning market will be indirect effects. In view of the economic cycle, the central air-conditioning production enterprises should strengthen the research and forecast of the central air conditioner market, grasp the market trend in time, adopt the flexible production system..
2.Energy, environmental protection policies for some products
  Electric energy tension so that part of the local government to introduce rationing policy will direct inhibition of people the purchase of electric refrigerating central air conditioner. At the same time because of the steam type refrigeration machine some coal as the fuel, will produce the waste gas, the waste residue and the dust and so on the pollutant. Increasingly stringent environmental protection policies will also make the market space for the class of products to shrink.
