Analysis of Development Trend of Building Materials Home Industry in 2015
2015 building materials home industry throughout the year's core word: change
“Change†can be understood as a change, and it can be understood as a change. In 2015, China's building materials industry will be the first year of industry subversion, and the trend of change has been irreversible. If the enterprises with traditional advantages in some industries still wait and see in 2014, and even resist the irritating touch brought about by the Internet, mobile Internet, and e-commerce, then most of the building materials home companies will start the Internet in 2015. The strategic layout of the first year. This view is based on the following three basic facts.
Analysis of Development Trend of Building Materials Home Industry in 2015
First: The in-depth analysis report of the building materials home industry shows that in the past 10 years, the leading brands in the various industries of building materials have made the offline terminal the ultimate. From the perspective of channel layout, industry leaders such as Icon, Nobel, Op, and Nippon All of them have more than 3,000 national stores, and their terminal layout has entered the four-tier market and even some townships. Although the growth of traditional channel layout and terminal precision cultivation still exists, the future can already be foreseen.
However, first and second-tier cities are being hit by the Internet and e-commerce, so it is inevitable that companies with traditional strong channels will begin to pay attention to new environmental changes in cities of grades one to three.
Second: In the past, the sales characteristics of Jin Jiuyin, the salesman of building materials and home furnishing, and sales that accounted for more than 60% of the sales volume in the second half of the year were completely broken in 2014. In the second half of the year, the market suddenly became cold, with the exception of a small number of industry leaders whose brands have spurred their advancement through rival markets. The remaining three or four line brands have undoubtedly felt the pressure.
With the lack of market growth and the year-round sales pattern tending to be stable, how do companies respond?
Third: industry leader brand cross-border business, price war, large-scale sports warfare This industry reshuffle in 2014 all began to highlight, so that we feel the atmosphere of the home appliance industry reshuffle.
Industry consolidation and reshuffling is an unavoidable topic for the next five years. Each market segmentation of each industry can have up to 3-5 brands that can survive. This cruel reality has been far away in the past and is now accelerating. Some second-tier and third-tier companies have already begun regional intensive cultivation in order to cope with future integration competition. In this environment, companies still have to change.
Therefore, although this is an old tune, the word “changing†will be particularly apparent in 2015. From 2015 to the next three to five years, the building materials home industry will completely establish a new market structure.
