Investigation and Analysis of Lighting Consumption Status of Urban and Rural Residents in China
/China Green Lighting Project "is a key energy-saving demonstration project currently being implemented in China. In order to grasp the marketing information of high-efficiency lighting products in time, understand the development of China's high-efficiency lighting industry and market, and consumers' understanding of efficient lighting. At the beginning of 2002, China Green Lighting Project Promotion Project Office and Beijing Huatong People Market Information Co., Ltd. and China Lighting Electrical Appliances Association jointly organized the first national survey on lighting power and lighting electrical products market. The survey was a national survey. Sexual sampling survey, including lighting electrical industry and lighting electricity survey, lighting electrical products manufacturers, sellers, units of large users, household users survey five parts. This article focuses on the survey related to home lighting The investigation of electricity. 2 Purpose and content of the survey A comprehensive understanding of the level of electricity consumption and electricity consumption of urban and rural residents in China, especially the awareness and consumption behavior of high-efficiency lighting products by consumers. As this survey is an activity of the China Green Lighting Project Promotion Project, the survey also includes consumer understanding and opinions on China's green lighting project. The main contents of the survey include: lighting consumption of urban and rural residents, proportion of high-efficiency lighting products; purchase of lighting appliances habits and needs; understanding and use of high-efficiency lighting products; market barriers to efficient lighting. 3 Survey Method 31 Sample Selection This survey uses a scientific probability sampling method. Due to the use of high-efficiency lighting electrical products and people's income levels, the principles and methods of selecting samples according to the above are used to investigate the regional and quantitative distribution of the final selected sample points. As shown in Table 1. To verify the regional distribution of the sample sample of the sample 1 sample, the second-order sampling frame, the second-order sampling frame, the third-order sampling frame, the urban sample size, the urban sample size, the sample size of the city, the name of the sample, and the name (a), Beijing 54 Zhumadian 56 Luancheng County, Jingjing County 54 Wuhan 54 Xiangtan 56 Nong'an County, Shuangyang District 54 Lanzhou 54 Linghai 56 Chang'an County, Lantian County 54 Harbin 54 Shuangliu County 56 Changle County, Minhou County 54 Kunming 54 Fenghua County 56 Dali Town, Salt Step Town 54 Subtotal 270 Subtotal 280 Subtotal 270 Total 820 Economic development factors and accessibility of the operation, the home user adoption is multi-level stratified sampling. The approach is to select three orders in accordance with the characteristics of the administrative region. The first order is the provincial capital city and the large-scale large-scale secondary city. The second order is small and medium-sized secondary cities, counties and county-level cities, and the third order is rural areas under the county and county levels. And then pumping the countryside). The first-order sampling frame is the residents of 28 provincial capitals and municipalities directly under the Central Government and large secondary cities; the second-order sampling frame is the national small and medium-sized secondary cities and county and county-level city residents: the third-order sampling frame is 2000 counties across the country. Rural areas near the county and county level cities. In order to ensure the representativeness of the sample, 820 samples were uniformly quotad. The total sample size of the first-order sampling frame was 270, the second-order sampling frame was 280, and the third-order sampling frame was 270. In the first-stage sampling frame, 28 provincial capital cities, municipalities directly under the central government and large-scale secondary cities are divided into five layers according to the clustering principle, taking into account the economic development level and geographical distribution factors, and randomly selecting one city in each layer, and then The number of samples is evenly distributed among the five extracted cities. In the second sampling frame, the national small and medium-sized secondary cities and county and county-level cities are divided into five layers according to the clustering principle, taking into account the economic development level and geographical distribution factors, and randomly selecting one county-level city in each floor. Then, the number of samples is evenly distributed among the five extracted county-level cities. In the third sampling frame, divide the county and county-level cities in the country into five layers according to the level of economic development, and then randomly select one county and county-level city in each floor, so that 5 counties and county-level cities are randomly selected. City, draw 1 to 2 rural areas under each county and county level city. The number of samples was evenly distributed among the five rural areas extracted. 3.2 The rationality of the distribution of the sample distribution, especially comparing the family structure of the sample with the actual family structure of the country, showing that the selected sample is roughly consistent with the distribution of the national family structure. Therefore, the representativeness of the sample can be considered good. Painting 7% Note: The inner circle is the distribution of the family structure in the country; the outer circle is the distribution of the family structure of the survey sample. Comparison of the family structure of the survey sample with the actual family structure in the country. This survey takes the form of household visits. In the actual interview, the total number of valid samples obtained was 856. 4 Survey results The following is a brief summary of the analysis results obtained from the survey data. Degree, in which the proportion of electricity consumption and residential electricity consumption in the first, second and third industries is 4%, 71%, 11% and 14% respectively. The total electricity consumption of residents in China is about 200 billion kWh, among which residents use lighting. Electricity is 67.1 billion degrees, urban residents consume 26.2 billion degrees, and township residents consume 40.9 billion degrees. The proportion of electricity used by urban and township residents to their total household electricity consumption was 25.4% and 38.2%, respectively. 42 The survey found that more than half of household users started using high-efficiency electric light sources. In 1995 and 1999, various high-efficiency electric light sources were reused. The rate is above 50%, and the use of thin tube straight tube fluorescent lamps is the highest, reaching 58.8%. The three main reasons for users to repurchase high-efficiency electric light sources are: high-efficiency electric light source, good lighting effect, power saving and easy installation; There are three main reasons for the lack of confidence in purchasing high-efficiency electric light sources: high-efficiency electric light sources have low service life, high price and fast light decay (). 4|11 The overall satisfaction evaluation of household s high-efficiency electric light source products and electronic ballasts is between “general†and “satisfactory†(Table 2) Annual total electricity consumption (100 million degrees) Average annual electricity consumption per household (degrees) Household households (10,000 households) Lighting electricity consumption as a percentage of total electricity consumption Household households (10,000 households) National urban and rural areas ( Note: 1 means very unimportant, 2 means not important, 3 means general, 4 means important, 5 means very important) evaluation of factors affecting the purchase of high-efficiency lighting electrical products by family users 4.5 Recognition of "China Green Lighting Project" by ordinary households in China The perception is still relatively low, with only 11.2% of households hearing it. The survey found that the biggest impact of the “China Green Lighting Project†on household users is to increase environmental awareness. Their suggestions for the "China Green Lighting Project" are "promoting manufacturers to improve product quality", "strengthening product quality supervision, combating counterfeit goods" and "enhancing publicity efforts". 4.4 Resident users of various high-efficiency electric light source products and The overall satisfaction evaluation of electronic ballasts is between “general†and “satisfactory.†In the analysis of many factors affecting consumers' purchase of high-efficiency lighting electrical products, the scoring method (1 means very important, 2 It means not important, 3 means general, 4 means important, 5 means very important. Evaluation, residents give priority to product safety and quality, score is 4.5, followed by brightness score 4.2, energy consumption score 4 points; lowest score It is the product brand. It is inferred that the brand effect of high-efficiency lighting products has not yet formed in the minds of consumers.
