“…The investment in telecommunications infrastructure and network facilities is both an important handgrip to improve the services of telecom operators and the important foundation of local economic development [4,5]. While more studies are aiming at telecom investment in the recent years, Aude et al [13] analyzed a large number of investment cases of Telecom Multinational Enterprises in Africa from 2000 to 2015, found there had been existed a big gap between the final deal prices and local market contexts, and then analyzed the key factors that influencing deal prices.…”

“…The investment indicators (such as "I1 investment in wireless access network," "I2 investment in transmission network," "I3 investment in service network," "I4 investment in supporting network," and "I5 investment in construction") have been used as the inputs, which could cover variety of telecom investments in network facilities. To fully describe the operational performance of provincial companies, we grouped the outputs into four sub-indices labeled SUPPLY, ADOPTION, USAGE, and REVENUE [4,8,25]. SUP-PLY measures the quality of networks to support telecom services, which includes two indicators: "S1 mobile phone exchange capacity" and "S2 size of carriers."…”

“…Recently, the new generation mobile communication networks (hereinafter referred to as "new generation networks"), such as 3G, 4G, and 5G, play an important role in the advancement of mobile internet and have received a vital concern [1][2][3]. During the upgrading period of new generation networks, telecom operators tend to keep an eye on the network investment performance, which is one of the key factors for deploying the new generation networks and arranging new mobile data services (hereinafter referred to as "new service") effectively [4,5]. Network investment performance is an important component of performance measurement for telecom operators, which means degree of the force that investment portfolios of different network facilities driving the operational performance improvement [4,6,7].…”

With the fast development of the mobile internet in recent years, the new generation mobile communication networks as the basic supporting have received widespread attentions. During the upgrading period of new generation networks, the telecom operators need to grasp the network investment performance, which is one of the key factors for deploying the new generation networks and arranging new services effectively. In this paper, first, we propose a method based on the dynamic DEA model and the sensitivity analysis to measure the network investment performance of telecom operators, which gives the managers and researchers insight into the changing process of the key influence factors on the investment performance. Then, we build the input-output indicators system of the DEA model from five dimensions, such as INVESTMENT, SUPPLY, ADOPTION, USAGE, and REVENUE, for a more complete and valid characterization to the network investment performance. At last, we apply the proposed method to conduct an empirical research on the operational data of one Chinese telecom operator from 2013 to 2015, which has been the initial launch phase of 4G network. Based on the result, we develop effective investment strategies for the upgrading period of networks, which also gives guidelines for the investment of 5G and other new generation networks in the future.

“…The new conceptual model is grouped into five subindices: INVESTMENT, SUPPLY, ADOPTION, USAGE and REVENUE, and the interaction among them are considered in our model (see Figure 1). INVESTMENT describes the telecom investment of network construction and optimization, which is both an important handgrip to drive the services of telecom operators, and the important foundation of local economic development [23], [24]. More studies are aiming at this field in the recent years, Du et al [25] proposed a method based on the dynamic DEA model and the sensitivity analysis to measure the network investment performance of telecom operators.…”

For the global telecom operators, mobile data services have gradually taken the part of traditional voice services to become the main revenue growth point. However, during the upgrading period of new generation networks (Such as 5G), new mobile data services are still at the stage of exploration, the network capabilities and the application scenarios are unmatured. In this phase, it is incomplete and misleading to simply measure the performance of new services from one dimension, such as data traffic or revenue, and the measurement should be dynamically changed according to the development of the new services. Therefore, telecom operators want to improve the existing performance measurement from the aspect of integrity and dynamics. In this paper, we propose Mobile-data-service Development Index (MDDI), and build a quantitative model to dynamic measure the overall performance of mobile data services. To approach a fuller understanding, we creatively bring investment indicators and networks reliability indicators into performance indicators system, and discuss the relationships among subindices and the selection of outcome criteria in MDDI. In the part of empirical research, we use the model to analyze the dynamic characteristics of a new mobile data service in China, and summarize the development strategies of every stage. The findings can also give guidelines for new services of 5G and other new generation networks in the future.

Resilience is learnable and broadly described as an individual's adaptive coping ability, its potential value for stress reduction must be explored. With a global coronavirus pandemic, innovative ways to deliver resilience training amidst heightened mental health concerns must be urgently examined. This systematic review aimed to (1) evaluate the effectiveness of digital training for building resilience and reducing anxiety, depressive and stress symptoms and (2) to identify essential features for designing future digital training. A three‐step search was conducted in eight electronic databases, trial registries and grey literature to locate eligible studies. Randomised controlled trials examining the effects of digital training aimed at enhancing resilience were included. Data analysis was conducted using the Stata version 17. Twenty‐two randomised controlled trials involving 2876 participants were included. Meta‐analysis revealed that digital training significantly enhanced the participants' resilience with moderate to large effect (g = 0.54–1.09) at post‐intervention and follow‐up. Subgroup analyses suggested that training delivered via the Internet with a flexible programme schedule was more effective than its counterparts. This review supports the use of digital training in improving resilience. Further high‐quality randomised controlled trials with large sample size are needed.
