As a new research interest, robots have surpassed human performance across several aspects. In this research, the authors wish to investigate whether robot adopters perform better than non-adopters in terms of export behavior, especially when distinguishing between different types of firms.

The authors try a new strategy to identify the extent of robot adoption by import data and compare the export trajectories of robot adopters and non-adopters by employing the propensity score matching-difference in difference (PSM-DID) method.

The authors find that robot adopters are more likely to enter export markets and improve subsequent export performance, as the gains from doing so can spread the reduction in variable production costs to a larger customer base abroad. But this rule does not always seem to work; for large-scale firms, robot adoption makes it easier to win export competition and increase market share, while small and medium-sized enterprises (SMEs) do not seem to enjoy any benefits from adoption. More importantly, robot adoption also leads to the fiercer market competition when improving the productivity of firms, which will threaten smaller non-adopters.

The findings provide new evidence for the scale bias of robotics and offer new insights into whether exporters or future exporters ought to adopt robots in production.

1. First, distinguishing from existing research, we explain the controversial results of previous work on robotics by providing evidence from export markets and using the concept of size bias, which helps to update the theoretical interpretation of robotics and provides new insights for current and future exporters to evaluate their robot adoption decisions.

2. Second, we extend previous research by further considering the potential robotics threats faced by non-adopters, especially we record that export gains of robot adopters are partially at the expense of smaller non-adopters, which provides new evidence for the rationale of SME protection policies and supplements robotics theory with new knowledge, such as the competitive game of firms related to robot adoption.

3. Third, to our knowledge, prior research tended to examine the economic effects of robotics through industry data provided by the IFR, this may lead to systematic bias due to the inability to distinguish the robot adoption intentions of different firms. In this respect, we try a new strategy through robot import data and further distinguish between robot adopters and non-adopters in the sample, which helps to mitigate the potential bias in the findings and provide a complement to the recently developed literature related to robotics.

4. Finally, as we pointed out earlier, robot adoption could be an interesting research work for the Chinese export market, which helps us to obtain some special findings, such as in assessing whether the benefits of robots are equally appropriate for economies that previously had an advantage in terms of labor.

The purpose of this paper is to propose an approach for aircraft taking off control in wind shear, which is a challenging issue for an aircraft.

Aircraft control in wind shear needs an anti-jamming controller. Symbolic control is an effective and adaptive method for complex dynamic system. In this paper, wind shear flight control laws are developed for the dynamics of a B-747 aircraft by using symbolic control. The problem of efficiently steering dynamical systems with disturbance by using symbolic control is considered, and theoretical analysis on the proposed approach is also conducted. The implementation of an altitude scheduling strategy with symbolic controller makes it possible for aircraft to escape serious wind shear.

This work improved symbolic control algorithm so that it can be applied to aircraft control problem. A series of comparative experimental results with proportional-integral-derivative controller demonstrate the feasibility and effectiveness of the proposed approach.

The symbolic control method developed in this paper can be easily applied to another aircraft control problems.

An improved symbolic control method is proposed for solving aircraft taking off problem in wind shear.

Low levels of human capital in rural China are rooted in the poor schooling outcomes of elementary school students. The purpose of this paper is to provide insight into the distribution of academic performance in rural China and identify vulnerable groups.

The authors draw on a data set of 25,892 observations constructed from 11 school-level surveys spanning nine provinces and one municipality in China conducted from 2013 to 2015.

The authors find that the distribution of academic performance is uneven across provinces and subgroups. In general, male students, Han, living in richer counties, living with their parents and studying in rural public schools do better academically than female students, non-Han, living in poorer counties, left behind and studying in private migrant schools in cities.

Using the results of this study, policymakers should be able to better target investments into rural education focusing on at risk subpopulations.

With limited data sources, the research on the academic performance of students in rural China is largely absent. The findings of this study help to fill the gaps in the literature base.

The purpose of this study is to present the results of an experiment that examines the effects of client management’s increased disclosure of related party transactions (RPTs) on auditors’ judgments of financial reports that contain RPTs.

This study used a 2 × 2 between-subjects experiment to investigate auditors’ judgments in response to questionable RPTs in a Chinese context.

The results show that the auditor participants assessed a lower likelihood that the client’s financial statements were intentionally misstated and that they were less likely to request additional evidence when the client management chose to disclose more, as opposed to less, detailed RPT information in their disclosure. Moreover, there was a significant interaction between disclosure level and client incentive to manipulate earnings on the likelihood of the auditor requesting additional evidence.

This study should be of interest to regulatory agencies that have expressed concerns over auditing practices related to RPTs.

The findings from this study help to provide a more in-depth understanding of disclosure literature by investigating voluntary RPT disclosure and the moderation role of clients’ incentives to manipulate earnings.
