What are the bad changes in the process of economic development in our country?

China has made some progress in economic development, but at the same time, some prominent contradictions and conflicts have emerged.

China is the world's second largest economy, accounting for more than 10% of the global economy. (2) The growth rate is generally stable. (3) Structural adjustment has been actively promoted.

2. Contradictions and problems that have emerged: (1) The rapid development of China's economy and the rapid development of some high-tech industries and original industries have brought tremendous pressure on resources and the environment. (2) Since the subprime mortgage crisis in the United States in October 2008 has evolved into a global financial crisis and has had a serious impact on China's first-class export-oriented enterprises, the labor demand of enterprises has declined sharply, the existing jobs have been seriously lost, and the number of unemployed has increased sharply, resulting in the further deterioration of China's employment and unemployment problems.

Extended Materials. 1. After the founding of the People's Republic of China, China has become one of the world's economic powers with development potential through large-scale construction in a planned manner, and the people's living standards have generally reached a moderately prosperous level. On January 18, 2021, the National Bureau of Statistics released data showing that in 2020, China's gross domestic product (GDP) exceeded the 100 trillion yuan mark for the first time.

Since the beginning of the 21 st century, China's economy has continued to maintain steady and high-speed growth. The market economic system has been initially established, the market plays a decisive role in the allocation of resources, and the macroeconomic regulation and control system is becoming more and more perfect. A pattern of common development of the non-public economy, with the public economy as the mainstay and individual, private, and foreign-funded economies developing together, has basically taken shape, and the mode of economic growth has gradually changed from extensive to intensive.

1.There is a strong environment and system to ensure economic development, which is an advantage that has existed since the founding of the People's Republic of China, and it is also an extremely important point.

2.It makes very effective use of the advantages of backwardness, which is the advantage of backward development.

3.In the face of different international economic environments, it is very beautiful to be able to adjust economic policies in a timely manner, especially the gradual transition from planning to market economy.

4.Long-term high savings rate and high investment rate.

5.There are a large number of accumulated foreign exchange reserves, an independent monetary policy and a fixed exchange rate system, which ensures that the real exchange rate is undervalued for a long time, so as to win a huge surplus; Capital is not allowed to enter and exit absolutely freely, and generally speaking, it is easy to enter and difficult to exit.

8.Chinese traditional cultural advantages, Chinese like to invest a lot of income in the education of the next generation; In Chinese values, collective interests are greater than individual interests, while the West is just the opposite; Chinese are diligent and studious.
