The dual-cycle new development pattern, a consequence of changing times, "superposes" multi-scale spatial-output theory and the regional division of labor under the condition of market economy. It also introduces a new force for developing new forms of urbanization. To explore this influence, the present study first internalizes two exogenous variables in urbanization-development dynamics: technological innovation and institutional reform. It then constructs a new urbanization-dynamics factors-analysis framework for the "fourdimensional driving forces model + innovation force + institution force", combines this with the principal component-regression model, which empirically analyzes the development dynamics of Chongqing's new urbanization since 2000. Accordingly, this study uses Porter's "diamond model" to systematically consider the new urbanization development path. The results demonstrate: (1) Innovation and institutional forces incorporated into the urbanization-dynamics factors-analysis framework have had a significant positive driving effect on the urbanization of Chongqing; of these, innovation is the most evident. The advantages of technological innovation and institutional reform now underpin development dynamics, responding to changing times in a new era; (2) Although the development of new urbanization in Chongqing is the result of "six-dimensional forces, " market and administrative forces are still the primary driving forces, followed by innovation and internal and external forces. Here, the driving effect of innovation on urbanization has surpassed the impact of administrative force during the second stage of urbanization in 2010-2018. The least significant effect is institutional force; it indirectly reflects that Chongqing's urbanization is an endogenous process. It is forecast and objectively necessary to construct a new development pattern; (3) Based on Porter's Diamond Model, researchers have pointed out problems in Chongqing, such as small growth volume, limited hinterland, insufficient market-purchasing power, unsustainable development, low-end products, and serious homogenization. To address this, the present study introduces specific countermeasures and suggestions for realizing high-quality urbanization development, based on six dimensions: developing advanced production factors; creating a unified free-flow market of factors; expanding market demand; promoting urban development; cultivating and developing leading and supporting industries by "expanding domestic demand, adjusting structure and deepening opening to the outside world"; and, seizing the opportunity to "go out" and build a high-quality service-oriented government. These results are expected to provide a theoretical basis and reference for research on development dynamics of urbanization in China, the high-quality development of urbanization in Chongqing, and the integration of the Chengdu-Chongqing dual city economic circle.
