Research on optimizing the layout of new quality productivity on cross-regional synergistic science and technology innovation and economic development

In September 2023, General Secretary Xi Jinping first put forward the new quality of productivity when he visited and researched in Heilongjiang. New quality productivity is "spawned by revolutionary breakthroughs in technology, innovative allocation of production factors, and deep transformation and upgrading of industries". Optimizing the layout of the new quality productivity can provide a new dynamic energy and a new path for promoting the coordinated development of regional economy and realizing the common prosperity of the region. This paper defines the connotation of new productivity and cross-regional collaborative scientific and technological innovation, conducts a deep analysis of the coordinated development of new productivity and cross-regional collaborative scientific and technological innovation in the eastern developed regions, explores the impact mechanism of optimizing the layout of new productive forces on cross-regional collaborative scientific and technological innovation and economic development, and puts forward policy recommendations for the benefit of cross-regional collaborative scientific and technological innovation and the quality of economic development.
