The subject of our research is the environmental management practices (EMPs) adopted by small and medium-sized hotel enterprises (SMHEs) to foster the development of sustainable business models. The aim is to analyse operational, communication and organizational practices and to explore whether or not the availability of public incentives encourages SMHEs to adopt EMPs, and, if it does, how. We use a framework based on a multi-dimensional approach according to the classification proposed by González-Benito and González-Benito (2006) and we add a supplementary variable (access to subsidies) to capture the importance of the public actor. The research was carried out in Trentino, a traditional tourist destination in the Italian Alpine Arc. We received 351 completed online questionnaires, of which 247 were considered valid. The data were analysed using Principle Component Analysis (PCA) applied to a polychoric correlation matrix. The PCA evidences three relevant latent dimensions which summarized more than 72% of the sample variance. The results demonstrate that the SMHEs adopted three different sets of EMPs, and that the role of public actor is crucial for financing the most expensive operational activities. The research narrows the knowledge gap with regard to a) the types of EMPs adopted by the SMHEs, b) the methods used to achieve this implementation. The research validates the inclusion of the supplementary variable within the framework, and thus the original nature of our study.

我们研究的主题是中小型酒店企业（SMHE）所采用的环境管理实践（EMP），以促进可持续商业模式的发展。目的是分析运营，沟通和组织惯例，并探讨是否有公共奖励措施鼓励SMHE采纳EMP，如果可行，如何进行。根据González-Benito和González-Benito（2006）提出的分类，我们使用基于多维方法的框架，并添加了一个补充变量（获得补贴）来体现公共行为者的重要性。这项研究是在特伦蒂诺（Trentino）进行的，特伦蒂诺是意大利阿尔卑斯山脉的传统旅游胜地。我们收到了351份完整的在线问卷，其中247份被认为是有效的。使用应用于多元相关矩阵的主成分分析（PCA）分析数据。PCA证明了三个相关的潜在维度，这些维度汇总了样本差异的72％以上。结果表明，SMHE采用了三套不同的EMP，公共行为者的角色对于资助最昂贵的运营活动至关重要。研究缩小了关于a） SMHE所采用的EMP的类型，b）用于实现此实现的方法。该研究证实了框架内补充变量的纳入，从而验证了我们研究的原始性质。
