  The new dual-cycle development pattern is based on meeting domestic needs, and its starting point and end point is to meet the people's growing needs for a better life. To build a new dual-cycle development pattern, the focus is to focus on the domestic big cycle and effectively link the domestic and international dual cycles. Based on the in-depth study of General Secretary Xi Jinping's important speech on "dual circulation" and the detailed review of existing literature, combined with the available data, this paper scientifically demonstrates the construction of an indicator system for a new dual-circulation development pattern. By constructing a model and setting the core variable "dual cycle interaction term", we can measure whether the effective linkage of domestic and international double cycles can effectively stimulate total factor productivity from the macro and micro perspectives, and verify the mediating effect of technological innovation at the micro level. , To solve the operability problem of empirical research at the macro and micro levels in the dual-cycle field.

  Firstiy, significant regional differences exist in the level of development of internal and external cycles constructed by the entropy method, that is, the eastern region is higher, and other regions gradually decrease. Secondly, in the macro-level empirical test, the dual-cycle effective linkage has a more significant promotion effect in the eastern region than other regions; in the micro-level empirical research, the dual-cycle effective linkage has generally improved the total factor productivity of enterprises. It has a more significant role in promoting state-owned enterprises, and larger enterprises have a more significant impact than small and medium-sized enterprises. Finally, the use of technological innovation as an intermediate variable between the new dual-cycle development pattern and the company's total factor productivity verifies that the new dual-cycle development pattern can act on the effective path of the company's total factor productivity through technological innovation. In summary, this article measures the development level of internal and external cycles by constructing a dual-cycle development level evaluation index system, and tests the effectiveness of the dual-cycle effective linkage in promoting regional high-quality development and solving the problem of "stuck necks" in enterprises. The study found that the dual-cycle effective linkage significantly improved the total factor productivity of regions and enterprises, especially in the eastern region and larger enterprises. Further research shows that technological innovation is effective as an intermediary variable for the dual-cycle effective linkage to promote the improvement of enterprise total factor productivity. This provides a theoretical basis for the government to build industrial policies to promote the improvement of independent innovation capabilities of enterprises and to solve the current problems of enterprise development.
