“商品化差距”在一个优雅而仔细的理论分析中，这本书展示了绅士化如何始终与制度和独特的语境过程交织在一起。Matthias Bernt提出了一个新概念，即“商品化差距”，并在三个经过充分研究的案例中进行了测试。有了这一点，绅士化的概念变得多种多样，在不同的城市背景下进行对话的可能性也扩大了。这是一本非常有价值的书！”
-詹妮弗·罗宾逊，英国伦敦大学学院人文地理学教授
“城市研究已经陷入普遍主义与特殊主义的僵局。马蒂亚斯·伯恩特（Matthias Bernt）正在打破这种僵局，他非常精确地描述了什么是普遍的，什么不是——以及如何将两者概念化。商品差距不仅是绅士化研究的关键贡献，也是比较城市化和城市研究的重要贡献。”
-Manuel B.Aalbers，比利时库鲁汶地理与旅游部
商品化鸿沟为绅士化研究领域提供了一个深刻的制度主义视角。这本书探讨了在伦敦、柏林和圣彼得堡的三个社区中，绅士化的运作与支撑、但也影响和限制绅士化的机构之间的关系。马蒂亚斯·伯恩特（Matthias Bernt）展示了不同的制度安排如何在不同的时间和地点促进、减速或改变绅士化。
这本书基于在英国、德国和俄罗斯进行的实证研究，包含了德国和俄罗斯有史以来第一次关于绅士化的英语讨论。它首先考察了广泛确立的“租金差距”理论的局限性，并提出了“商品化差距”的新概念接下来，本书将探讨英国、德国和俄罗斯的不同制度背景如何为这些差距创造条件，从而实现绅士化。商品化差距是研究人文地理学、住房研究、城市社会学和空间规划的研究人员和学者不可或缺的资源。
The Commodification Gap: Gentrification and Public Policy in London, Berlin and St. Petersburg
THE COMMODIFICATION GAP ‘In an elegant and careful theoretical analysis, this book demonstrates how gentrification is always entwined with institutions and distinctive contextual processes. Matthias Bernt develops a new concept, the “commodification gap”, which is tested in three richly researched cases. With this, the concept of gentrification becomes a multiplicity and the possibility of conversations across different urban contexts is expanded. A richly rewarding read!’
—Jennifer Robinson, Professor of Human Geography, University College London, UK
‘Urban studies has reached a stalemate of universalism versus particularism. Matthias Bernt is breaking out of this deadlock by being very precise about what exactly is universal and what is not – and how one can conceptualize both. The Commodity Gap is a key contribution to not only gentrification studies, but also to comparative urbanism and urban studies at large.’
—Manuel B. Aalbers, Division of Geography & Tourism, KU Leuven, Belgium
The Commodification Gap provides an insightful institutionalist perspective on the field of gentrification studies. The book explores the relationship between the operation of gentrification and the institutions underpinning – but also influencing and restricting – it in three neighborhoods in London, Berlin and St. Petersburg. Matthias Bernt demonstrates how different institutional arrangements have resulted in the facilitation, deceleration or alteration of gentrification across time and place.
The book is based on empirical studies conducted in Great Britain, Germany and Russia and contains one of the first-ever English language discussions of gentrification in Germany and Russia. It begins with an examination of the limits of the widely established “rent-gap” theory and proposes the novel concept of the “commodification gap.” It then moves on to explore how different institutional contexts in the UK, Germany and Russia have framed the conditions for these gaps to enable gentrification. The Commodification Gap is an indispensable resource for researchers and academics studying human geography, housing studies, urban sociology and spatial planning.
