Abstract
Mixed-use development is increasingly popular in land use planning and zoning, fostering a combination of residential, commercial, and cultural uses into one space. However, there is a lack of understanding of the vertical mix office space within a high-rise commercial building and the dynamics of the industry mix between buildings. This paper examines the spatiotemporal patterns of industry mix between and within office buildings in Sydney CBD from 2006 to 2017, using the data obtained from the City of Sydney floor space and employment surveys. This is the first study that identifies the dynamics of an industrial ecosystem in central Sydney, which has transformed to homophily land blocks, with increasing vertically heterogeneous office buildings, over the past decade. In addition, the study found that the significant clustering of anchor tenants, such as finances, hospitalities, and knowledge-based industries, are apparent.

Changing industry structure in cities shows the city’s competitiveness and productivity
This paper addresses the limitations of the mixed-use concept and practice in urban planning: the classification of urban uses, doubt of the relationship between mixed-uses and economic productivity, different scales and settings of urban heterogeneity, and the understanding of mixed-use, given spatial heterogeneity
One example is the construction of 10 Carrington, a 134 m high, mixed-use office and retail building in Wynyard Place, which will comprise of 27 levels of premium-grade office space; the new business districts in Barangaroo, to the west, will offer new supplies to the office market
Summary
Changing industry structure in cities shows the city’s competitiveness and productivity. In Norway, provided a framework for an integrated mixed-use urban development that applies mixed-use planning tools in major hubs, which are centrally located, with public transport, accompanied by a combination of commercial and residential zones [21]. Most studies classify urban uses into the five categories of office, commercial, residential, public space, and industrial uses, and investigate the mixed-use development in cities, based on these classifications. Han and Hawken [37] stated that one of the essential characteristics of cities is economic heterogeneity, which is critical to the identity of cities, and to economic productivity and innovative potential They argued that mixed-use planning should extend to various types of industry mix, in different settings and scales (e.g., districts, neighbourhoods, blocks, and buildings as the vertical mix in buildings and horizontal mix in urban blocks)
