In order to understand the current living conditions of large and complete enterprises and small and specialized enterprises, the thematic planning team divided into two groups and designed a questionnaire for manufacturers and distributors respectively. the investigation task was completed through customer visits and market visits. As mentioned above, the objects of this research refer to those enterprises that focus on subdivision fields and whose products are more professional in Subdivision fields, and those enterprises that are large and full refer to those enterprises that are large in scale. enterprises with complete product lines but more or less defects in product cost performance and channels. According to the data of this market survey and recovery questionnaire, 40 of the respondents belong to the large and full category, and 60 of the respondents belong to the fine and specialized category. Through the investigation, the reporter found that the number of dealers who specialize in a brand has a tendency to decrease. In the same batch of dealers, there were 74 dealers specially acting for one brand in the past, and now there are only 63 dealers specially acting for one brand. Thus it can be seen that the loyalty of dealers to brands has declined. if the big and the whole enterprise does not accelerate the improvement in cost performance, the number of loyal customers will probably gradually decrease. According to the survey results of dealers, according to the survey results, dealers now have a variety of main products, and there is no excessive centralized sales of certain types of products. However, from their main products, it can be seen that most of the products sold by distributors are common and popular products in the market, and those non-mainstream products account for a small share. There are many reasons for dealers to choose a certain brand product, but the speed of new products on the brand is fast, the product is the brand's fist product, and the high cost performance of the product is the main reason why dealers make the final choice. Distributors said that these three main reasons have a great impact on the sales of products. As distributors, they will certainly choose products that sell better. Most of the products purchased by distributors now are specially agents of a brand, and only 40% of the products of different categories choose different brands. Many dealers said that they started to represent a certain brand before, and they have been acting for the brand for a long time. A kind of trust has formed between the two sides and they are too lazy to change other brands. Compared with the present, the former distributors chose to specialize in the products of a brand, and the distributors who chose to buy separately only accounted for about 20. The dealer said that he did not think so much before, but only saw which brand's products were sold well and represented which brand. Even if other brands that did not sell well had good products, they would not act as agents. According to the survey results of manufacturers, according to the survey of product categories selected by customers, 35 of the 12 categories were bought. there are 20,35 categories purchased in the whole category, which is the choice of most customers when purchasing products, with a ratio of 45; Judging from the profit point of the product, the profit is 5 to 40, and the profit can reach more than 20. So far, only a few enterprises can do it. In the investigation, the reporter found that the proportion of LED tubes/spotlights and LED ceiling lamps produced by lighting enterprises as fist products is large, followed by LED ceiling lamps. The above three products have become necessities for lighting enterprises. Modern people's demands for the living environment at home are constantly improving. Most of them advocate that the living environment can create a simple and warm atmosphere, while LED overall home lighting has sprung up in recent years. LED products began to break into thousands of lights with their simple appearance and energy saving advantages. What followed was that enterprises seized the opportunity to vigorously develop and produce to meet the needs of consumers. When visiting the market survey, the reporter also found a phenomenon: the more comprehensive the enterprise produces, the more his fist products may not be. One of them has a comprehensive product range. there are also 4 kinds of fist products. This is the one that the reporter saw in the survey, and it stands out in the market survey questionnaire. One kind of fist product is the current situation of most enterprises, followed by three kinds of fist products. According to statistics, the products with high sales volume, LED tube/spotlights, LED Sky lamps and LED ceiling lamps are three pillars, which are far away from other varieties of products, reflecting the great potential of the overall home market in the future.
