Northeast, used to be one of the most prosperous areas

Northeast China is a geographical, cultural and economic region in China, not an administrative region. The word "northeast" first appeared in "zhou li · shi fang shi". "Northeast yue you state, its town mountain yue doctor wu lu." In the book of mountains and seas, "beyond the northeast sea, in the great wilderness", "there are mountains, called not salty, there is the state of sushen".
According to historical data, before 1954, there were 14 municipalities directly under the central government, including tianjin, Shanghai, nanjing, xi 'an, chongqing, guangzhou, wuhan (hankou), shenyang, luda (dalian), anshan, fushun, benxi, changchun and Harbin. At that time, northeast China was the most prosperous region in the Shijiazhuang to Hohhot flight country. The first automobile, the first jet plane and all the industrial base came from northeast China. Even the eldest son of the republic. Some of our elders are still familiar with the slogans of later industrial revolution such as daqing.
As early as the early days of the founding of the People's Republic of China, northeast China was under the control of the state due to its strong industrial strength, which was called state ownership at that time. Employees of state-owned enterprises were very popular. With the reform and opening up, the northeast is still the same as before, including the traditional concept that enterprises or public institutions can guarantee the harvest in case of drought or flood. However, with the reform and opening up in the south, there was a release of long-held resentment. With the vigorous development of the Internet, the private sector was suddenly pushed to the top of the world.
Although the bureaucracy of China's traditional feudal society lasted for thousands of years, it still has lingering warmth. Northeast China grew up under such lingering warmth, as far back as Ming and qing dynasties, as far as the republic of China, and till today.
Northeast China's economy started early and made historic contributions to the development and expansion of new China, which strongly supported the national economic construction. In 2002, the GDP of the three northeastern provinces reached 1,1603.2 billion yuan, accounting for 11.3 percent of the country's GDP. This includes 149.11 billion Shijiazhuang to Bangkok flight yuan added value of the primary industry, 576.54 billion yuan added value of the secondary industry, and 434.67 billion yuan added value of the tertiary industry. The proportion of the tertiary industries in the GDP was 12.9:49.7:37.5. The per capita GDP is 10,833.5 yuan.
Northeast China built a complete industrial system in the 1930s and became the most advanced industrial base in northeast Asia. After the founding of the People's Republic of China, due to the original industrial base and close to the Soviet union, many heavy industry construction projects were arranged in the northeast. The northeast once accounted for 98 per cent of China's heavy industry. There are three industrial belts in northeast China, namely, shenzhou-dalian industrial belt, chang-ji industrial belt and ha-daqi industrial belt. It has formed two major city clusters, namely, liaozhong south city cluster and Harbin chang city cluster.
