Abstract: The construction of new urbanization stands as a pivotal lever and carrier for the comprehensive implementation of the primary task of high-quality development and the new development concepts. It also represents a vital pathway to achieving rural revitalization. By analyzing the connotation of new urbanization, clarifying its measurement and realization path, and integrating the essence and intrinsic requirements of highquality development and new development concepts, this paper proposes a practical path for new urbanization. This path is supported by investment in new infrastructure construction, guided by the carrying capacity of the environment serving as a 'traffic light', and steered by comprehensive performance acting as a 'baton'. Based on the model of new urbanization construction that integrates ecology and performance, this paper conducts an empirical analysis of the advantages and disadvantages of achieving new urbanization in underdeveloped contiguous areas, using the typical and significant example of the urban development belt in Southern Shandong. It is proposed that, while adhering to the ecological red line, we should respect market efficiency, enhance comprehensive performance with new-quality productivity, dynamically adjust and continuously optimize regional urbanization construction. Through these efforts, this paper aims to realize innovative, coordinated, green, open, and shared new urbanization.
