Comparative analysis of electricity consumption levels in various cities in Zhejiang
Shaoxing connects with Ningbo City in the east, Taizhou City and Jinhua City in the south, and Hangzhou City in the west. In 2019, Shaoxing's gross product (GDP) was 578.1 billion yuan, an increase of 7.2% over the previous year at comparable prices. The province has an average of 0.4%, ranking fifth in the province and 37 in the country. From the perspective of the total electricity consumption of the whole society in the past three years, Shaoxing ranks fourth in the province after Hangzhou, Ningbo and Jiaxing. Shaoxing's private economy is active, and the local economy is characterized by its textile industry and related industrial chains. In terms of industrial electricity consumption in the past three years, it ranks 4th in the province after Hangzhou, Ningbo and Jiaxing. The city has an area of 8,279 square kilometers. At the end of 2019, Shaoxing has a permanent population of 5.057 million and an urbanization rate of 68.4%. It is a small and medium-sized city as a whole. Judging from the electricity consumption of residents in various cities in Zhejiang Province in the past three years, it ranks 6th in the province after Hangzhou, Wenzhou, Ningbo, Taizhou, and Jinhua. Residents' electricity demand needs to be further tapped.

Comparative analysis of electricity consumption level and growth rate of Shaoxing
Compared with the electricity consumption and growth rate of the whole country and Zhejiang Province, the change trend is relatively similar. In addition to the 8.98% growth rate of electricity consumption in Zhejiang Province in 2016, which was significantly higher than the 2.25% in Shaoxing and 4.94% in the country, the growth rate of electricity consumption in Shaoxing over the years showed a high degree of synergy with the country and Zhejiang Province. Excluding 2016 Influenced by the annual electricity growth rate, the correlation coefficient between Shaoxing s electricity consumption growth rate and Zhejiang s electricity consumption growth rate is 0.958, and the correlation coefficient with the national electricity consumption growth rate is 0.897. The electricity growth trend is closer to that of Zhejiang Province. slight upward trend, while the proportion of electricity consumption in Shaoxing continues to drop below 10%, and the growth of electricity consumption in Shaoxing slightly lags behind The provincial average.

Comparative analysis of industrial electricity consumption structure
In terms of industrial structure, Shaoxing, under the correct leadership of the Zhejiang Provincial Party Committee and Government, has focused on cultivating industrial development, speeding up project construction, and forming two leading industries dominated by modern service industries and manufacturing. In terms of electricity consumption structure, Shaoxing's secondary industry accounts for the largest proportion of electricity consumption. Over the years, the proportion of secondary industry electricity consumption has exceeded 78%, which is about 7 percentage points higher than Zhejiang Province and about 9 percentage points higher than the national level. Industrial power consumption accounts for the smallest proportion, while tertiary industry power consumption and residential power consumption account for the middle.    Electricity consumption in agricultural production is mainly concentrated in water conservancy irrigation and primary processing of agricultural products. The characteristics of electricity consumption in agricultural production are relatively strong seasonality and relatively large fluctuations. From 2010 to 2019, the proportion of electricity consumed by the primary industry in Shaoxing increased from 0.65% to 0.70%, showing a slow increasing trend. The proportion of electricity consumed by the primary industry in Zhejiang Province decreased from 0.61% to 0.44%, first slowly After increasing and decreasing, the proportion of electricity consumption in the country s primary industry decreased from 2.35% to 1.08%, showing a decreasing trend. Although Shaoxing's agricultural electricity consumption accounts for a relatively low proportion of the total electricity consumption in the whole society, it accounts for a relatively high proportion compared with the change in the average electricity consumption of the primary industry in Zhejiang Province. The change trend is significantly different from that of the whole country and Zhejiang Province. As a large agricultural city, although this part of the demand accounts for a small proportion, it still deserves sufficient attention.
In recent years, through optimizing the environment and attracting investment, Shaoxing has successively introduced many large enterprises to settle in, which has greatly promoted the growth of regional electricity demand. Shaoxing, Zhejiang Province, and the country's secondary industry electricity consumption ratio decreased from 84.24%, 78.22%, 74.70% in 2010 to 78.23%, 70.71%, and 68.32% in 2019, all showing a decreasing trend. Shaoxing has the smallest decline, Zhejiang Province has the largest decline. The change trend of the electricity consumption of the secondary industry in Shaoxing is consistent with that of the whole country and Zhejiang Province, but the proportion of industrial electricity consumption is higher than the average level of the country and Zhejiang Province.
Shaoxing is a famous tourist city. The tourism industry will drive the development of catering, accommodation, commerce and other industries, and the electricity consumption of the tertiary industry will inevitably increase significantly. Shaoxing, Zhejiang Province, and the national tertiary industry accounted for electricity consumption increased from 6.71%, 9. smallest increase and the country has the largest increase. The electricity consumption of the tertiary industry in Shaoxing has the same trend as the country and Zhejiang Province in terms of changes, but the proportion of electricity consumption is lower than the average level of the country and Zhejiang Province, indicating that Shaoxing s electricity demand for the tertiary industry still needs further exploration and improve.
The proportion of residential electricity consumption in Shaoxing, Zhejiang Province, and the whole country increased from 8.40%, 11.31%, and 12.22% in 2010 to 10.53%, 13.62%, and 14.19% in 2019, showing an increasing trend. Among them, Zhejiang Province has the largest increase and the country has the smallest increase. The change trend of residential electricity consumption in Shaoxing is consistent with that of the country and Zhejiang Province, but the proportion of electricity consumption is lower than the average level of the country and Zhejiang Province. It may be integrated with regional development, new district development, and business and living district construction. The resulting population migration is related.

Growth trends and characteristics of electricity consumption in major industrial sectors
Shaoxing s industrial electricity consumption accounts for more than 77% of the total electricity consumption of the whole society. We will further subdivide the electricity consumption structure of industrial industries, and study the electricity consumption characteristics of Shaoxing s main industries and Shaoxing Power Supply Company s support for electricity consumption in major industries.
Take the industrial power consumption structure of Shaoxing in 2018 as an example. Among them, the manufacturing industry accounts for 91.53%, the electric heating gas and water production and supply industries account for 8.06%, and the mining industry accounts for only 0.41%. The manufacturing industry consumes significantly more electricity than the other two industries, which is the main industry driving the growth of electricity consumption in Shaoxing. In order to deepen the research on the electricity consumption characteristics of the pillar industries for the growth of electricity consumption in Shaoxing, further subdivide the electricity consumption structure of the manufacturing industry. The manufacturing industry can be subdivided into 29 industries, with electricity consumption accounting for 44.604% of the textile industry, 8.364% of the chemical fiber manufacturing industry, and 7.602% of the chemical raw material and chemical products manufacturing industry, ranking the bottom three. The leading position is the instrument and meter manufacturing industry at 0.077%, the petroleum, coal and other fuel processing industry at 0.015%, and the tobacco product industry at 0.001%. It can be seen from the electricity consumption structure of the subdivided industries that the textile industry, chemical fiber manufacturing, chemical raw materials and chemical product manufacturing are the pillar industries of Shaoxing.
