Abstract
This research explores how central-city shopping districts could be transformed to support a post-Covid lifestyle, where people re-embrace community, local streets and walking while relying more on online shopping. By reviewing metropolitan/city development plans since the 1980s and mapping changes of retail provisions, urban environment and pedestrian movements in Melbourne's Hoddle Grid in the twenty-first century, this paper shows that planning policies focusing on people-centred experiences in the central-city shopping district helped to improve retail resilience. This paper thus adds insights to understanding the relentless retail landscape changes and has implications for central-city retail planning in the post-Covid era.

Regional greenway implementation requires a complex governance structure to deal with regional-local, cross-jurisdictional and cross-sectoral relations. This paper explores how these three intergovernmental relations are shaped by different governance structures and how they influence regional greenway implementation outcomes. An analytical framework was proposed considering four structural factors (size, specialisation, order and anarchy) and China's inherited tiao (vertical)-kuai (horizontal) system of authority. By analysing a case-study project with evolving governance structures over time, the paper reveals that a more powerful, sectorally specialised, autonomous and inclusive local coordination office is ideal to foster institutional linkages within administrative jurisdiction, between adjacent governments and across government hierarchy. These links are essential for efficient and integrated greenway implementation in city-regions.
