本章提出大模型的概念，作为区域分析和城市研究的一种新的研究范式。大模型是针对大地理区域的精细尺度区域/城市分析/模拟模型。随着大/开放数据的广泛使用，计算能力的增加，以及先进的区域和城市分析/建模方法，大模型使得克服地理尺度和模拟分辨率之间的权衡成为可能。本章阐述了大模型的概念、特点和潜在的应用。我们通过几个案例来说明我们的研究进展和大模型的应用。这些项目包括绘制中国所有城市的城市区域地图，进行地块级城市模拟，以及几个正在进行的研究项目。这些应用大多可以在全国范围内采用，并且都集中在精细尺度级别，例如地块，街区或乡镇（街道）。预计大模型将标志着大/开放数据时代的城市分析和区域研究的一个充满希望的新时代。
This chapter proposes the concept of big model as a novel research paradigm for regional analysis and urban studies. Big models are fine-scale regional/urban analysis/simulation models for a large geographical area. With the widespread use of big/open data, the increased computation capacity, as well as the advanced regional and urban analyzing/modeling methodologies, big models make it possible to overcome the trade-off between geographical scale and simulation resolution. In this chapter, the concept, characteristics, and potential applications of big models have been elaborated. We presented several case studies to illustrate the progress of our research and the application of big models. They include mapping urban areas for all Chinese cities, performing parcel-level urban simulation, and several ongoing research projects. Most of these applications can be adopted across the whole country, and all of them are focusing on a fine-scale level, such as a parcel, a block, or a township (sub-district). It is expected that big models will mark a promising new era for the urban analysis and regional studies in the era of big/open data.
