China has come up with the new development pattern for a number of reasons. These include:

• To address the challenges of economic growth. China's economy has grown rapidly in recent decades, but it is now facing a number of challenges, such as slowing growth, rising inequality, and environmental degradation. The new development pattern is designed to address these challenges and ensure that China's economy continues to grow in a sustainable way.
• To achieve high-quality development. China is no longer satisfied with simply achieving high economic growth. It now wants to achieve high-quality development, which means that it wants to grow its economy in a way that benefits all of its citizens and protects the environment. The new development pattern is designed to achieve this goal.
• To become a global leader in innovation. China is aware that it needs to become a global leader in innovation if it wants to remain competitive in the long term. The new development pattern places a strong emphasis on innovation, and it aims to create an environment where businesses and individuals can thrive and create new technologies.
• To promote sustainable development. China is committed to sustainable development, and the new development pattern is designed to help the country achieve this goal. The pattern emphasizes the importance of protecting the environment and ensuring that economic growth is not achieved at the expense of the environment.

Overall, the new development pattern is a comprehensive plan that aims to address the challenges facing China and ensure that the country continues to grow in a sustainable and prosperous way.

In addition to the reasons mentioned above, China is also facing increasing pressure from the international community to address its environmental record and its human rights practices. The new development pattern is seen as a way for China to address these concerns and show that it is committed to becoming a responsible global stakeholder.
