The territorial space development pattern of the target construction should be able to help the full circulation and optimal allocation of social elements and resources, the society in the region is relatively fair, the development opportunities and welfare of people are equal, and the development of people, society, economy, and environment is coordinated and sustainable. This article aims to develop and control the three-dimensional optimization of the land space based on the spatial equilibrium model. This article first analyzes and introduces the spatial equilibrium model, then constructs an evaluation index model for the suitability of territorial spatial three-dimensional optimization development, and determines the index weights for the suitability of territorial spatial three-dimensional optimization development. Then, it analyzes the supply-demand relationship of the three-dimensional optimization development of the territorial space, discusses the imbalance of the supply and demand of the territorial service space, and finally summarizes the overall characteristics of the supply and demand of the three-dimensional optimization development of the territorial space based on the spatial equilibrium model. The research results show that under the conditions of rapid development, some development zones represented by the High-tech Zone in City B are seriously inadequate for industrial land use. In 2020, the proportion of industrial land in the high-tech zone of City B will exceed 17.69% of the 2015 plan. The demand for production space in the development zone is greater than the supply, which will inevitably bring certain pressure to industrial transformation.

“…Land-use and transport have traditionally been the main foci of applied urban modeling (Wegener, 1994(Wegener, , 2004. Over the past decades, significant research went into improving the operationality, comprehensiveness, and representativeness of urban models, informed by real-world applications of established models in various cities across the globe (Anas and Liu, 2007;Waddell, 2011;Jin et al, 2013;Wan and Jin, 2017). Applied urban models have played an important role in not only informing policy and interventions for cities and infrastructure, but also establishing a new science of cities through academic research (Batty, 2013).…”

This paper demonstrates that a shift from a purely technical to a more socio-technical perspective has significant implications for the conceptualization, design, and implementation of smart city technologies. Such implications are discussed and illustrated through the case of an emerging urban analytics tool, the Cityscale Digital Twin. Based on interdisciplinary insights and a participatory knowledge co-production and tool co-development process, including both researchers and prospective users, we conclude that in order to move beyond a mere "hype technology," City-Scale Digital Twins must reflect the specifics of the urban and socio-political context.

“…A cross-year validation process (2000–2010) was conducted following the method from Wan and Jin (2017). With the location of jobs and the number of housing units as the main inputs, the predicted residents’ location in 2010 has a good fit with the observed one, as the r-square reaches 0.94.…”

Aspirations and realities of polycentric development: Insights from multi-source data into the emerging urban form of Shanghai

The polycentric idea has recently been reinvigorated in many rapidly urbanising countries, but the paucity of reliable and disaggregated data has so far made it almost impossible to understand the policy feedback there. This paper capitalises on official statistical data, novel online data, and proprietary digital data, and builds a dynamic spatial equilibrium model for understanding the past lessons and future options for developing new urban sub-centres. Following the post-2010 situation of a negative sign of monocentric bid-rent curve and physical polycentric growth, we assemble, corroborate, and validate multi-source data sets within the model to explore possible polycentric development scenarios . The data analysis and model tests show that over time, the balance between jobs and housing provision appears to have been lost, and it is insufficient job opportunities in the planned sub-centres rather than any lack of housing development that has led to the loss of this balance. Localised circumstances have also played a role in this overarching pattern of evolution. The insights are cogent for current decision making regarding polycentric planning and growth, especially in developing countries.
