基于最短距离法的机场辐射范围研究——以陕西省为例

针对最短距离法在选择机场时没有考虑到机场性质、忽略掉了机场所在地区的地域经济水平等一系列因素，导致计算结果十分不合理的问题，利用模糊理论对最短距离法进行优化，阐述机场辐射范围的界定方法，建立机场辐射范围计算模型。以陕西省为例进行实证研究，对陕西省的4个民用机场辐射范围进行计算。最后对机场建设提出建议。     

Digital touch in sponsorship: Getting closer to the brand through virtual reality

Supporters are consuming more and more sporting events through digital platforms. Brands should adapt to these new consumption patterns in order to strengthen their connection with their customers. Today, researchers and practitioners can create more interactive and enjoyable experiences through virtual reality (VR) applications. Through two studies conducted on VR during sporting events, we show that mentally representing the touch experiences of players on the field reduces the psychological distance between the supporter and the player, which strengthens the supporter's attachment to the team and, through the same attachment, to the sponsor (Study 1). We also highlight that these positive effects of VR compared to real touch (using a player's jersey) is linked to the improvement of immersion, which stimulates touch imagery (Study 2). We discuss the implications of this research for theory and practice in the sports business and other sectors.     

Determinants of technical efficiency and farmers’ crop choice rationality: A case study of rural Gansu,China

Land exchange based on market transactions in which lessors and lessees participate voluntarily not only makes them better off but also enhances the overall efficiency of land use and agricultural production. However, it is worthwhile to empirically explore the effect of land rental on overall technical efficiency in the context of Chinese agriculture because non-farm household producers have increasingly entered the farming business as cultivators. If such producers underperform farm households in terms of efficiency, land consolidation does not necessarily deliver the desired outcome. This study demonstrates that the development of land rental markets improves agricultural technical efficiency at the aggregate level. Another important issue addressed in this study is to examine farmers’ crop choice rationality. China offers an interesting case in this respect. This is because, while the central government has long strived to maintain a high grain self-sufficiency rate, the relative prices of farm products have recently moved in favor of non-grain products. Our empirical result suggests that there is room for further increase in farm revenues of Gansu’s producers by shifting resources away from cereal toward horticultural production.     

Bilateral Relations and Exports: Evidence from Google Big Data

This paper investigates the effect of bilateral relations on exports using data from Google Global Data. It finds that bilateral relations significantly reduced the negative effect of cultural distance on exports, indicating that they can promote exports by reducing trade costs. The paper finds that higher average Goldstein scores of events correlated with more exports and that bilateral relations had a larger effect on trust-intensive products, indicating that positive relations built trust and decreased the emotional distance between trading partners. The results also show that bilateral relations promoted exports at both the intensive and extensive margins but with a greater effect on the latter. Finally, bilateral relations had a greater positive effect on developing countries than on developed ones. The results were qualitatively unchanged when endogeneity issues and robustness concerns were considered.     

Once upon a time in a foreign market: The role of cultural distance in the economic performance of multilateral non-equity partnerships

As a consequence of globalization and advancements in technology, international collaborations, which bring together partners from different cultural backgrounds, have become increasingly prominent in the business world. While several studies have examined the impact of cultural distance on the performance of such partnerships, they have tended to focus on bilateral relationships, and the results they have produced are conflicting. By building on the resource-based view and distinguishing the differences between the concepts of cultural distance among partners and the cultural distance of partnerships from target markets, the present study provides insights into the role of cultural distance in the performance of multilateral project-based non-equity collaborations. Drawing on a sample of 1183 movies that were released in the U.S. between the years 2000 and 2020, this study demonstrates that while projects co-produced by culturally distant partners have yielded higher revenues, the cultural distance of partnerships from target markets can have a negative impact on economic performance. Furthermore, the results show that partnerships formed with firms that originated in countries that have greater diversity perform better in the target market, and such partnerships manage cultural distance more efficiently.     

COVID-19 crisis and the efficiency of Indian banks: Have they weathered the storm?

The purpose of this study is to determine whether Indian banks were able to weather the COVID-19 storm. We estimate banks’ deposits-generating and operating efficiencies using a two-stage directional distance function-based network data envelopment analysis (DDF-NDEA) approach and seek to capture the immediate impact of COVID-19 on these efficiency measures by comparing their magnitudes in the pre-pandemic (2014/15–2019/20), just 1-year prior to the pandemic (2019/20), and during the pandemic year (2020/21) periods. The study looks at whether the impact of the COVID-19 pandemic was uniform across ownership types and size classes. The empirical findings suggest that the Indian banking system was resilient and withstood the immediate impact of the COVID-19 pandemic. During the study period, however, the large and medium-sized banks experienced some efficiency losses. By and large, regardless of bank group, banks have shown resilience to the shock of the global health pandemic and improvements in efficiency.
