Abstract
Purpose
The purpose of this paper is to comprehensively examine the influence of formal and informal institutional differences on enterprise investment margin, mode and result.
Design/methodology/approach
This paper is based on 2,440 micro samples of large-scale outbound investment from 609 Chinese enterprises from the years 2005 to 2016.
Findings
The study has found that formal institutional differences have little impact on investment scale, but significantly affect investment diversification. In order to avoid the management risks brought by formal institutional differences, enterprises tend to a full ownership structure. However, the choice between greenfield investment and cross-border mergers and acquisitions is not affected by formal institutional differences. In contrast, the impact of informal institutional differences is more extensive. Both formal and informal institutional differences significantly increase the probability of investment failure. Further research found that the Belt and Road Initiative (BRI) bridges the formal institutional differences.
Originality/value
The study concludes that developing the BRI, especially cultural exchanges with countries alongside the Belt and Road, will help enterprises to “go global” faster and better.

Abstract
Purpose
The Belt and Road Initiative (BRI) is the most comprehensive and substantial international cooperation platform, creating a new market influenced by economic and political factors. In this paper, the authors aim to examine whether and how the BRI impacts the Chinese enterprises' corporate environmental responsibility (CER).
Design/methodology/approach
Based on China's listed firms' database from 2011 to 2018, the authors use the PSM-DID method, an econometrics method combined with propensity score matching (PSM) and difference-in-differences (DID), to conduct causal inference between the BRI and Chinese enterprises' CER and conduct a series of robustness analyses. Moreover, the authors explore the mechanisms underlying the main effect from both market and non-market perspectives.
Findings
The results suggest that the BRI significantly increases Chinese enterprises' CER. Further analyses show that market competition and government support are two possible mechanisms through which the BRI has an effect on the enterprises' CER.
Originality/value
The research study supplements existing work on the environmental effects of the BRI at a microlevel and adds to the literature on the drivers of CER. The findings offer valuable insights into governments and scholars by demonstrating that CER is a crucial tool for Chinese enterprises to gain a competitive advantage in the increasingly competitive markets along the BRI.

Abstract
Purpose
Reliable conceptual cost estimation of large-scale construction projects is critical for successful project planning and execution. For addressing the limited data availability in conceptual cost estimation, this study proposes an enhanced ANN-based cost estimating model that incorporates artificial neural networks, ensemble modeling and a factor analysis approach.
Design/methodology/approach
In the ANN-based conceptual cost estimating model, the ensemble modeling component enhances training, and thus, improves its predictive accuracy and stability when project data quantity is low; and the factor analysis component finds the optimal input for an estimating model, rendering explanations of project data more descriptive.
Findings
On the basis of the results of experiments, it can be concluded that ensemble modeling and FAMD (Factor Analysis of Mixed Data) are both conjointly capable of improving the accuracy of conceptual cost estimates. The ANN model version combining bootstrap aggregation and FAMD improved estimation accuracy and reliability despite these very low project sample sizes.
Research limitations/implications
The generalizability of the findings is hard to justify since it is difficult to collect cost data of construction projects comprehensively. But this difficulty means that our proposed approaches and findings can provide more accurate and stable conceptual cost forecasting in the early stages of project development.
Originality/value
From the perspective of this research, previous uses of past-project data can be deemed to have underutilized that information, and this study has highlighted that — even when limited in quantity — past-project data can and should be utilized effectively in the generation of conceptual cost estimates.

Abstract
Purpose
The majority of Hong Kong filmmakers have pursued co-production with China filmmakers for having the Mainland market at the expense of local styles and sensitivities. To many critics, the two-part series of Ip Man and Ip Man II provide a paradigmatic case of film co-production that sell the tricks of Chinese kung fu, regurgitating the overblown Chinese nationalism against Japanese and kwai-lo. The purpose of this study is to rectify such observation of the Ip Man series.
Design/methodology/approach
The authors read the series deconstructively as a postcolonial text in which Hong Kong identity is inscribed in the negotiated space in between different versions of Chinese nationalism.
Findings
The analysis points to the varying subversive features in the series from which Hong Kong’s colonial experiences are tacitly displayed, endorsed and rewritten into the Chinese nationalistic discourse whose dominance is questioned, if not debased.
Originality/value
This paper advances new research insights into the postcolonial reinvention of kung fu film and, by implication, the Hong Kong cinema in general.

Abstract
Purpose
The purpose of this paper is to implement a glass-curtain-wall cleaning robot driven by a double flexible rope, so as to replace manual cleaning. The glass-curtain-wall, because of its excellent daylighting performance, damp-proofing characteristics, heat insulation properties and aesthetics, is widely used in modern city buildings. For glass-curtain-wall buildings, regular cleaning of the glass-curtain-wall is necessary to ensure that the surface of the building appears clean and tidy, which in turn contributes toward preserving the overall aesthetic appearance of the city. Currently, the primary method of cleaning glass curtain walls is manual cleaning by workers on a suspended platform.
Design/methodology/approach
The mechanical structure of the proposed glass-curtain-wall cleaning robot driven by a double flexible rope is inspired by the way a spider moves by pulling its silk draglines in the air. For self-locking protection and increased rope friction, the robot’s moving section includes a worm reducer and multislot master–slave roller. The cleaning section comprises a water tank, control valve, shower nozzle and brush. The wall adsorbing section is realized by a double rotor. The workspace of the robot is analyzed. Flexible rope winding and unreeling control of the cleaning robot is deduced. The force of the cleaning robot when the double rotor is working is analyzed and calculated. The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope is established, and experiments wherein the robot moves along a preset track, as well as cleaning experiments, are performed.
Findings
The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope can move along the preset track, satisfy the design functions and clean effectively. The experimental results verify the validity and practicality of the robot.
Research limitations/implications
The implication of this research is that a glass-curtain-wall cleaning robot model driven by a double flexible rope fulfills the movement strategy and drive-type requirements for cleaning glass curtain walls. The limitation of this research is that it is difficult to implement rapid cleaning.
Originality/value
The traditional method of manual cleaning by workers on a suspended platform will be changed after the glass-curtain-wall cleaning robot is manufactured, and the advent of this cleaning robot for the low- and mid-rise buildings will reduce the cost of cleaning buildings, improve the working environment and enhance production efficiency.

Abstract
Urban water bodies play an important role in reducing summertime urban heat island (UHI) effects. Previous studies focused mainly on the impact of water bodies of large areas, and there is no analysis of the efficacy and scale effect of how small and medium-sized water bodies reduce the UHI effects. Hence, these studies could not provide theoretical support for the scientific planning and design of urban water bodies. This study aims to confirm, within different scale ranges, the efficacy of a water body in reducing the summertime UHI effects. We propose a scale sensitivity method to investigate the temporal and spatial relationship between urban water bodies and UHI. Based on the scale theory and geostatistical analysis method in landscape ecology, this study used the platforms of 3S, MATLAB, and SPSS to analyze the distance-decay law of water bodies in reducing summertime UHI effects, as well as the scale response at different water surface ratios. The results show that the influence of water surfaces on UHIs gradually decreases with increasing distance, and the temperature rises by 0.78 °C for every 100 m away from the water body. During daytime, there is a scaled sensitivity of how much water surfaces reduce the summertime UHI effects. The most sensitive radius from the water was found at the core water surface ratio of 200 m. A reduction of UHI intensity by 2.3 °C was observed for every 10% increase of the average core water surface ratio. This study provides a theoretical reference to the control of heat islands for the planning and design of urban water bodies.
