An in-depth understanding of the main factors behind built-up development is a key prerequisite for designing policies dedicated to a more efficient land use. Infill development policies are essential to curb sprawl and allow a progressive recycling of low-density areas inherited from the past. This paper examines the controlling factors of built-up expansion and densification processes in Wallonia (Belgium). Unlike the usual urban/built-up expansion studies, our approach considers various levels of built-up densities to distinguish between different types of developments, ranging from low-density extensions (or sprawl) to high-density infill development. Belgian cadastral data for 1990, 2000 and 2010 were used to generate four classes of built-up areas, namely, non-, low-, medium- and high-density areas. A number of socioeconomic, geographic and political factors related to built-up development were operationalised following the literature. We then used a multinomial logistic regression model to analyse the effects of these factors on the transitions between different densities in the two decades between 1990 and 2010. The findings indicate that all the controlling factors show distinctive variations based on density. More specifically, the centrality of zoning policies in explaining expansion processes is highlighted. This is especially the case for high-density expansions. In contrast, physical and neighbourhood factors play a larger role in infill development, especially for dense infill development. 深入了解建设发展背后的主要因素是设计更高效土地利用政策的关键先决条件。填补式开发政策对于遏制蔓延和逐步更新历史遗存的低密度地区至关重要。本文考察了瓦隆（比利时）建设膨胀和致密化过程的控制因素。与通常的城市/扩建研宄不同，我们的方法考虑不同层次的建设密度，以区分从低密度扩张（或蔓延）到高密度填充开发的不同开发类型。文章利用1990年、 2000 年和 2010年的比利时地籍数据生成了四类建设区，即无密度、低密度、中密度和高密度地区。我们根据研宄文献，对与建设发展有关的一些社会经济、地理和政治因素做了操作。然 后，我们使用多项逻辑回归模型来分析这些因素对1990年至2010年这二十年间不同密度之间转变的影响。研宄结果表明，所有控制因素都显示出基于密度的独特变化。更具体地说，分区政策在解释扩张过程中的中心地位是突出的。高密度扩展尤其如此。与之形成对比的，物理因素和邻里因素在填充式开发中起到了较大的作用，特别是对于密集填充式的开发。
