（1）cold chain equipment industry development overview and trend:
Cold chain equipment industry closely related to the development of cold chain industry. Cold chain logistics mainly applied in food (including agricultural products), medicine, chemicals, electronics fields, among which food cold chain and pharmaceutical cold chain occupy a larger proportion. Compared with developed countries, China's cold chain logistics development is still at an early stage, characterized by low refrigerated transport rate, high perishable product spoilage rate and imperfect infrastructure. With the gradual maturity of cold-chain business models, China's cold-chain service market scale has been maintaining continuous expansion since 2011-2013 year average growth rate was 24.30%. According to Roland Berger forecasted data due to macro policies and market demand pull effect Chinese cold-chain logistics industry will maintain a year-on-year growth of 25% until the market size reaches approximately 4.7 billion yuan in 2017-2018.
（2）Bus air conditioning equipment industry development overview and trend:
Benefiting from sustained economic growth in China, improvement of highway infrastructure construction level increase urban construction projects public transportation services levels etc., the bus market steady growth coupled with new energy buses school buses tourism vehicles increasing trends , according to CAAM data shows that domestic production volume from 2005 increased from 26360 units to reached up to $59 million units in 2015 The annual compound growth rate reached up to $7/65%.
3、Sub-market developments overview & Trend
Currently main focus on commercial display cabinet series products belong end-use cooling devices for retail sales terminal application.
Commercial Display Cabinets are more professional than household refrigerators or ice cabinets; they not only have better freezing function but also serve as important advertising tools for manufacturers promoting their products through these cabinets.
Accordingly commercial display cabinet product is a customized differentiated cooling device downstream equipment whose market scale directly relates national consumption demand fast-moving consumer goods producers channel promotion efforts.
China Commercial Display Cabinet Market Scale Prediction: As urbanization continues steadily upward income levels rise changing consumer habits demands for safety enhancement through government support Commercial Display Cabinet Market Scale will continue growing rapidly.
