This paper aims at estimating the regional and sectoral impacts of the Covid-19 pandemic in the state of Sergipe, Brazil in 2020. We use an input-output model with partial hypothetical extraction. The main results suggest a significant reduction in economic activity in the state, particularly in the Transport and Industry sectors. On the other hand, the Real estate and Food and Accommodation sectors have a greater capacity for recovery with the introduction of an emergency aid program. The municipalities with the largest absolute impact on gross domestic product are Aracaju, Canindé de São Francisco and Nossa Senhora do Socorro, two of them located in the metropolitan area of Aracaju.

Reducing carbon emissions is the only way to solve the global climate problem, which obviously requires the joint efforts of all regions. From the perspective of carbon emission reduction demand, this research obtains the data of low-carbon patents and CO2 emissions from 2000 to 2019, and then explores the innovation effect of low-carbon technology transfer in the Yangtze River Economic Belt (YREB). We draw the following conclusions: (1) Low-carbon technology transfer has a positive impact on low-carbon technology innovation. However, a large number of low-carbon technology transfers are concentrated between developed regions in the YREB at present. (2) No matter from the perspective of total amount or efficiency, carbon emission reduction demand can play positive moderating role in the process of exerting the innovation effect of low-carbon technology transfer, indicating that the transfer of low-carbon technologies to regions with high demand is efficient. (3) The moderating effect of carbon emission reduction demand in different regions has regional heterogeneity. Carbon emissions per unit of GDP plays a greater role in moderating the innovation effect of low-carbon technology transfer in the eastern region, while CO2emissions plays a greater role in the central and western regions. Therefore, we propose to strengthen the transfer of low-carbon technologies between developed and less-developed regions, and adopt differentiation strategies according to the actual situation of each region. Our research has deepened the understanding of environmental economic geography on the innovation effect of low-carbon technology transfer, and has reference significance for global low-carbon technology cooperation.

The recent economic, technological, and social shocks have led to a period of high economic uncertainty. The term “economic resilience” has been used to describe how regional clusters deal with and adapt to various shocks. This paper aims to analyze the elements that influence the resilience trajectory of a cluster. We conduct qualitative and exploratory research on the centennial Wine Cluster in Serra Gaúcha, Brazil, using data sources, interviews, and documents. To this end, we first identify seven elements that influence cluster resilience from the literature review. Subsequently, through an empirical case study, we verify whether these elements could represent the resilience of clusters. The results show that these seven elements are integrable and represent dimensions that explain the resilience of the cluster analyzed. Moreover, the findings highlight that resilience and resistance to crises are the historical results of improvements and the development of new routines for clustered companies. This study contributes to the cluster resilience literature and presents elements explaining how regions can adapt to and deal with shocks.

Since the mid-1980s, there has been a boom in world heritage site (WHS) inscriptions in China. Nevertheless, incumbent studies have not sufficiently explained why cities are enthusiastic about and capable of joining the boom. They tend to attribute such enthusiasm to the WHS values in heritage protection and tourism development. However, why stakeholders have motivations and opportunities to create the boom and what institutional environments support the craze are still yet to be answered. This paper investigates the boom through the concept of embeddedness to display how multi-scalar institutional contexts in China stimulate and sustain WHS nomination. This study argues that the enthusiasm for WHS inscription is embedded in the political-economic interests of stakeholders on different scales. At international and national levels, WHS nomination is regarded as a political tool to address diplomatic agendas, shape national honor, and balance regional development. On a local scale, WHS inscriptions can serve as a solid pretext for local states in China to fulfill their strong developmental imperatives and break financial constraints. These imperatives are embedded in China's transitional institutional environment, associated with power decentralization, central-local fiscal rearrangements, and the top-down system of cadre evaluation. In this context, local states are ambitious of initiating large-scale development projects to boost local development. WHS nomination has become a pretext for local states to fulfill extraordinary development in tourism and other industries, such as the real estate industry. This study discloses the hidden political economy behind the WHS inscription boom using the cases of Wulingyuan and the South China Karst.

We indirectly analyze the residential environment for long-staying internationals in Seoul, Korea, by extending the image–satisfaction–loyalty mechanism widely used in tourism, specifically by examining the internationals' satisfaction and loyalty. We consider residential difficulties, sociodemographics, and survey years along with image as exogenous variables and evaluate satisfaction not only in terms of its absolute but also its relative level, which is the difference between absolute satisfaction (AS) and previous expectation. Tourism studies have measured loyalty using individuals' intention to recommend to another and their own revisit intention, but we evaluate the revisit intention with place attachment/hometown perception, which is more suitable for long-staying residents. The variables are measured with 2016–2018 data from an annual quality of life survey for Seoul residents (n = 5279 individuals) and analyzed with structural equation modeling. Our results show that the conventionally used AS is associated only with recommendation intention, but the relative satisfaction (RS) both with recommendation intention and hometown perception. Regarding the exogenous variables, AS is substantially affected by image and RS is somewhat strongly influenced by residential difficulties. However, image is the principal determinant of loyalty level, whether recommendation intention or hometown perception. These findings confirm the applicability of the image–satisfaction–loyalty mechanism not only to short-staying inbound tourists but also to long-staying international residents.

Using insights gained from Jacobian externalities, we consider how a more diverse economic industrial base relates to business survival rates. While a low survival rate is often perceived negatively among policy-makers, evidence suggests that business exit is part of a dynamic and robust economy. The high opportunity cost of continuing with a struggling business in a more diversified economy may ultimately sway entrepreneurs with less competitive ventures to exit leading to lower survival rates. We model average 5-year survival rates at the county level annually from 1990 to 2012 employing a spatial panel Durbin specification. The data support the central hypothesis that more diversified economies increase the opportunity costs of operating an underperforming new business, thereby lowering survival rates.

Scholars demonstrated the importance of house planners in the creation of environmentally friendly homes. Despite the lack of broad agreement on the type of freehold estate that could reduce urban sprawl, the authors agree on the role of government and developers in housing planning and construction. According to a recent study, the government and developers are investing in freehold estates to promote sustainable urban growth. However, this study employs urban growth theories to explain the policy's success. First, we examine the rate of urban growth and the trends in urban sprawl. The affordability of ground-floor and three-story buildings is then assessed. The findings show that 19.36 square kilometers of built-up area contributed to land use expansion in Abomey-Calavi, Benin Republic, between 1974 and 2015, and four districts are at higher risk of environmental degradation. To mitigate this, three-story buildings could be inclusive and improve efficient land use, thereby limiting urban sprawl.

By examining China's province-level data, this paper uses governmental intervention theory to investigate the extent to which governmental policy interventions alleviate the impact of the COVID-19 pandemic on local economic growth. Results suggest that stronger government intervention during COVID-19 pandemic boost the economic recovery, and the effectiveness of governmental policy interventions is contingent on pandemic severity and local economic endowment. Specifically, facilitating effect of government intervention on economic growth is effective in all provinces, and the impact of government intervention is more pronounced in the province with more diagnosed cases, a high level of marketization and fiscal income.

This paper examines the impact of highway construction on the size distribution of manufacturing firms using Chinese firm and highway network data. I construct instrumental variables using historical and counterfactual road approaches to identify the causal effects of highway construction. I find that highway construction can increase firm size dispersion and market concentration. Areas near highways have a higher number of firms, more outsourcing activities, and more large firms; while areas further from highways have a higher share of new entry firms.
