Although the phenomenon of spatial agglomeration and its associated productivity premium applies to many industries, scholars have only recently considered agglomeration in the tourism industry. To ...avoid overestimation of the agglomeration effect and provide strong empirical evidence for policy formulation related to productivity improvement, we develop a theoretical framework to identify and decompose the contributions of spatial agglomeration to the productivity of hotel and catering enterprises. Using (Abel & Deitz, 2015) Chinese firm-level data for the hotel and catering industry from China's Second National Economic Census in 2008 and (Ahlfeldt & Pietrostefani, 2019) data from the 2007–2011 China Tax Census and 2009–2014 China Key Tax Source Survey, this study finds (Abel & Deitz, 2015) obvious agglomeration effects in the hotel and catering industry and that spatial agglomeration improves the average productivity of such enterprises in large cities; (Ahlfeldt & Pietrostefani, 2019) the competition is more fierce for hotels and catering enterprises in big cities, with high-productivity companies benefitting and low-productivity businesses suffering; (Andersson et al., 2007) low-productivity hotel and catering enterprises in big cities flee to smaller cities, that is, there is a clear sorting effect and (Au & Henderson, 2006) some high-productivity enterprises in big cities have migrated to small cities, indicating negative selection effects. The results of robustness tests validate these conclusions.
•This paper uses the hotel and catering industry (HCI) data from China for study.•The agglomeration effect attributes to HCI's productivity premium in big cities.•High-productivity companies benefit from the fierce competition in big cities.•Low-productivity enterprises in large cities choose to flee to small cities.•Some high-productivity enterprises in the big cities relocate to small cities.
The article is devoted to the study of catering enterprises strategy implementation in the conditions of economic crisis situations of 2020–2022. In particular, the article highlights the foreign ...scientists’ points of view regarding the definition of the “strategy implementation” concept, and the process approach to the definition is provided as a fundamental one. The scientific novelty lies in the fact that on the basis of the study key catering market trends for the period 2020–2022 were identified. The following main statistical indicators were used: the turnover of catering in the Russian entities and per capita, the number of places in catering enterprises and the availability of catering enterprises per 1,000 population. It was concluded that apart from the ongoing post-coronavirus trends, such as ensuring a high level of quality and safety of manufactured products, changing the supply chains, delivery of finished goods and takeaway format, in modern conditions, consumers are becoming more economical and rational in their expenses and are trying to optimise their budget. In 2022 and 2023, the following trends remain: establishment of interaction between catering enterprises and consumers, personalisation of clients, support of positive “word of mouth” and establishment of partnerships with local suppliers of products and ingredients to ensure supply stability. An assessment of catering enterprises strategy implementation with consideration to the influence of the identified trends is emphasised as a direction for further research.
We study a rich production-routing problem with time windows arising at a catering services company. The production part consists of assembling the meals to deliver. It considers release times to ...ensure freshness of the products to be delivered and is also restricted by due times incurred by the constructed routes. Production employee shifts together with a compatible production schedule must be determined. The routing part consists of building vehicle routes that can contain multiple trips and must satisfy customer time windows and vehicle capacity. Routing and production costs, including a guaranteed minimum paid time for the drivers and the production employees, are minimized under various constraints. To solve this complex problem, we propose an exact branch-price-and-cut algorithm. We introduce a new branching rule that imposes on one branch a lower bound on the production costs. Computational results obtained on instances derived from real-world data sets show the effectiveness of this branching rule. Overall, our algorithm is able to solve to optimality instances with up to 25 orders and four products in less than two hours of computational time. To tackle larger instances involving up to 50 orders, we turn the proposed algorithm into a heuristic by avoiding a complete enumeration of the search tree and develop two other matheuristics based on this branch-price-and-cut heuristic.

Catering facilities have a significant impact on the environmental sustainability of any destination. While travelling, people waste more food, eat more and prefer environmentally less sustainable ...products. This unsustainable behaviour is spatially conditioned: tourists move almost exclusively within a small part of a destination (the so-called limited area) where only a limited number of catering facilities are located. These businesses are therefore the key drivers of the environmental sustainability. The main objectives of this paper are to investigate the size of the limited area, number of catering options spatially accessible to tourists and finally to assess the environmental vulnerability of 38 European destinations associated with the limited area tourists usually visit and with the number of catering facilities that are accessible for tourists. Based on the spatial analysis considering the location of catering facilities, geo-located photographs and Airbnb listings, the limited area was calculated, and four indicators were implemented to assess the environmental vulnerability. The results showed that tourists move in only 4.4 km2 (3.3% of a city administrative boundary). In this area, millions of tourists have access to 685 catering facilities. In terms of spatial conditionality of food consumption, Venice, Amsterdam, and Florence are among the most environmentally vulnerable destinations. Furthermore, Venice and Florence also lack the environmental potential as a strong majority of catering facilities is located within their limited areas. On the contrary, Geneva and Thessaloniki were assessed as the least environmentally vulnerable destinations in our sample. Paris is the destination with the highest environmental potential, as 84% of its catering businesses are located beyond the borders of the limited area.
