from oil lamps to smart grids, from dirt roads to highways, "lights and phones upstairs and downstairs" has turned from a dream into a reality... the leap in infrastructure over the past 75 years has laid a solid foundation for jiangsu's economic development and paved the way for people's happy life. the royal road.

power generation and electricity consumption are important indicators to measure the economic and social development of a place. in jiangsu in 1949, the installed capacity of power generation equipment was only 99,000 kilowatts, and the annual power generation was 220 million kilowatt hours. by 2023, jiangsu's installed power generation capacity will increase to 180 million kilowatts, and power generation will reach 627.25 billion kilowatt hours.

railway, as an important artery for economic development, has also witnessed jiangsu's rapid progress. by the end of 2023, the province's railway mileage will reach 4,623.1 kilometers, an increase of 2,275.1 kilometers compared with 2012, including 2,541.4 kilometers of high-speed railways, an increase of 1,867.9 kilometers. the highway mileage has increased from 2,781 kilometers in 1949 to 158,741 kilometers. as the mileage increases, high-grade highways have grown from scratch to more. on the yangtze river, the opening of the nanjing yangtze river bridge has achieved a breakthrough in jiangsu's cross-river channels. now there are 18 river-crossing channels, realizing the transformation of natural chasms into thoroughfares.

by the end of 2023, the total length of optical cable lines will exceed 4.509 million kilometers, and the number of fixed internet broadband access ports will reach 105 million, ranking second in the country. the number of 5g base stations invested and constructed in the province has reached 237,000, ranking second in the country. build an information network with extensive coverage, efficiency and convenience.

after seventy-five years, jiangsu has drawn a magnificent picture of rapid infrastructure development.

"jiangsu is located in the eastern coast and the yangtze river delta. it is an important wing of the integrated development of the yangtze river delta and has unique location advantages. in the 75 years since the founding of new china, the mileage of built roads in the province has increased 56 times, and every village has been connected to roads and rail tracks. jiangsu's skeleton has been basically formed, transportation airports have been fully implemented, and transportation service levels have been greatly improved, making it a veritable transportation province. " jiang zhaoyi, a special researcher at the jiangsu regional modernization research institute and deputy director of the provincial financial research institute, said that the huge changes in transportation are just a matter of time. the tip of the iceberg of jiangsu’s earth-shaking infrastructure construction. since the founding of new china, jiangsu has continued to invest in infrastructure construction and achieved remarkable results. since the 18th national congress of the communist party of china, the province's infrastructure development has advanced by leaps and bounds. the average annual growth rate of infrastructure investment has increased by 8.8%, and the contribution rate to all investment growth has increased significantly.

electricity is the lifeline of economic development. building a new jiangsu that is “strong, prosperous, beautiful, and high” cannot be separated from the guarantee and support of electric power. since the 18th national congress of the communist party of china, the province's electricity and heat production and supply industry has invested a total of 1.31 trillion yuan, effectively ensuring the growing demand for electricity.

"on the one hand, the province's sustainable power capacity has been improved, effectively ensuring economic development and people's livelihood needs. for example, during the summer of 2024 when power supply is guaranteed to meet the peak, the highest power load in jiangsu's entire network hit a record high seven times, reaching a maximum of 147 million kilowatts. , a year-on-year increase of 11.3%, but the power supply seems to be "easy": the overload of important equipment is zero, and the demand side response is zero. on the other hand, green power construction has achieved initial results, and the installed capacity of new energy sources such as wind power and photovoltaics in our province has exceeded 10%. with an installed capacity of 50 million kilowatts, the offshore wind power capacity exceeds that of the united states, germany and other countries.” jiang zhaoyi said that after years of investment and construction, jiangsu power grid has become the provincial power grid with the highest load in the country, and its electricity load exceeds that of eu countries, south korea and australia.

entering the information age, jiangsu has bravely stood at the forefront, vigorously promoted new infrastructure, and delivered outstanding results. whether it is the total length of optical cable lines, the number of fixed internet broadband access ports, or the number of 5g base stations built, jiangsu ranks among the best in the country. the province has built an efficient and smooth modern information network to effectively promote the comprehensive digital transformation of the economy and society.

"next, jiangsu must find the breakthrough point for the deep integration of technological innovation and industrial innovation, promote the transformation of the advantages of enriched innovative resources into the advantages of industrial technological innovation, and strive to promote the development of new productive forces with high-level scientific and technological self-reliance." jiang zhaoyi analyzed that we must continue to promote infrastructure construction, especially make arrangements in advance for new infrastructure to better serve the construction of a new development pattern and promote high-quality development.

【story】

in early autumn, pukou railway station is a calm and peaceful scene. the sun shines on the renovated green brick and red walls, giving the old station a touch of warm color. nowadays, what we welcome here is no longer tourists in a hurry, but tourists from all over the world. occasionally, elderly uncles and aunts would sit on the wooden chairs in the square in front of the station and chat, or introduce the past glory of the station to young tourists.

in the winter of 1918, zhu ziqing bid farewell to his father here and wrote "back view". at that time, pukou railway station was a transportation hub. after the nanjing yangtze river bridge was opened to traffic in 1968, trains no longer ferried across the river from pukou via the pier. passenger traffic was suspended at pukou railway station, which was restored in 1985 and converted into a freight station in 2004. today, it has become a new cultural landmark in nanjing, with tourists from all over the world coming here to reminisce about an era.

every turn of pukou railway station is a microcosm of the continuous development and changes in the transportation field of jiangsu and even china. for a city, the train station where people come and go is a gathering place for passengers and a witness to history.

in the mobile phone of liu yongmei, the former director of nanjing south passenger transport of nanjing station of the shanghai railway bureau, there is a collection of photos recording key nodes of several railway stations in nanjing. looking back at these railway stations that have become prosperous due to the times, it is like taking a time machine and traveling through a time tunnel.

in 1995, liu yongmei was a passenger transporter at nanjing west railway station. at that time, there was only one train to kunming, chengdu, nanchang and other places every day. the ticket hall and waiting room were overcrowded, and even the toilets were crowded.

"nanjing west railway station is the terminal station of the shanghai-nanjing railway and the starting station of the ningxia-tonghu railway. it starts arranging passengers to board the train one hour before driving, but it still feels that there is not enough time." liu yongmei said that at that time, the average daily number of passengers was about 10,000 the number of people going to work is as busy as a "war". most of the tourists carry large and small bags, and most of them go out to work. "every time during peak travel periods such as the spring festival and busy farming season, the carriages are often overcrowded, crowded with people, and things weighed down. four conductors must be arranged in each carriage to provide relief. it is very difficult to move in the carriage, and some people even go to i can’t even squeeze out of the car even if i stand.”

in october 2006, liu yongmei was transferred to nanjing station. on april 18, 2007, the national railway speed increased for the sixth time. nanjing station developed rapidly and took on a completely new look.

"in the past, the 311-kilometer journey from nanjing to shanghai took at least 6 hours and 8 minutes. later, the harmony emu reached a top speed of 250 kilometers per hour, shortening the journey to 1 hour and 58 minutes." "passengers only care about three points: convenience and speed. , on time." witnessing the speed increase of trains, the upgrade of services, and the improvement of station software and hardware, liu yongmei lamented that the improvements in transportation and other infrastructure over the past few decades are precisely to meet the increasing needs of the people.

on june 28, 2011, nanjing south railway station, the largest railway station in asia, was completed and opened. liu yongmei pulled out a photo taken on february 6, 2011, which recorded the scene when the nanjing south railway station was just built. the surrounding area was deserted, in sharp contrast to the busy scene today.

"i witnessed every step of the growth of nanjing south railway station." during those days, the three members of liu yongmei's team walked an average of more than 30,000 steps a day. at that time, they dreamed that it would be great if the station could have an average daily passenger flow of 100,000. data show that since the official operation of nanjing south railway station on june 30, 2011, the number of passengers at nanjing south railway station has increased year by year, with an average of 23,600 people per day at the beginning of the operation and an average of 171,200 people per day by 2024. on april 6, 2024, 276,000 passengers were transported, setting a record high in the history of nanjing south railway station in a single day.

"the speed of the green train was 43 kilometers per hour, and now the speed of the fuxing train is 350 kilometers per hour." liu yongmei said that nanjing south railway station is now one of the five departure stations of the beijing-shanghai high-speed railway, connecting shanghai-hancheng, ning'an, ning-hang and many other places. an important railway line, it has become a large railway hub with 3 stations and 28 lines. “with the continuous improvement of transportation infrastructure, the popularization of high-speed rail and bullet trains, and the implementation of electronic tickets, travel efficiency has been improved while also greatly improving the travel experience.”

at the end of the interview, liu yongmei pointed to a new picture she had saved recently, which was a photo of the start-up site of the nanjing north railway station hub project on september 13. nanjing north railway station will be linked with nanjing south railway station and nanjing railway station to form a new pattern that radiates in all directions. in addition, the concept of intra-station transfer at nanjing north railway station and south railway station has been further optimized to achieve "waist transfer".
