Quality management practices have become increasingly important as firms seek to obtain quality certifications to dominate markets. To date, adequate research evaluating the effects of quality management is lacking. In this work, we used Chinese quality awards to evaluate a firm’s quality level. A PSM-DiD (propensity score matching and difference-in-difference) model describing the relationship between quality award effects and financial benefits in terms of return on assets was developed. We further used a hierarchical regression to examine the influence of operational performance on financial benefits. The results show that quality awards cannot assure their winners a higher return on asset. Indicators of operating performance, such as less lead time and higher inventory turnover, can significantly enhance firms’ profitability. The moderating effects of operational performance suggest that firms may focus on how to translate quality management practices into business improvement. This study also contributes to the operation management literature by describing how firms need outstanding financial performance for sustainable development and continuous improvement.

This research establishes the evaluation index for the innovation efficiency of the cultural and creative enterprises, by aid of the DEA-BCC method under the premise of the Variable Return to Scale (VRC), conducts evaluation and decomposition on the innovation efficiency of these sample companies based on the sample data of the A-stock 77 cultural and creative listed companies in China from 2010 to 2013, and further conducts comparative analysis on the difference of the innovation efficiency of the cultural and creative enterprises in different regions of China, which provides suggestions on the development balance of the industry in different regions.

To address the issues of roadway instability and severe air leakage in goaf areas during overlapping coal pillar mining in shallow multi-seam coalfields, this study takes the 22,209 working face of Huojitu Shaft in the Shendong Daliuta Mine as the research object. Using the discrete element method (DEM), the optimal layout of roadways in the lower coal seam and the corresponding evolution of overburden fractures were simulated. In addition, the effectiveness of goaf backfilling in controlling overburden air leakage channels was analyzed and verified. The results indicate that the width of coal pillars in the upper seam should be greater than approximately 23 m to ensure that roadways remain in a stress-stable zone. Roadways in the lower seam should be horizontally arranged within a range of 35–55 m from the center of the overlying coal pillar. This layout effectively avoids placing the roadway beneath the high-stress concentration zone or the pressure-relief area of the goaf. After mining the upper coal seam, the overburden collapse zone takes on a “trapezoidal” shape, and mining-induced fractures develop upward to the surface, forming vertical and inclined fracture channels that penetrate to the surface, resulting in severe air leakage in the goaf. Following the mining of the lower seam, the interlayer strata are completely fractured, leading to secondary development of fractures in the overlying old goaf. This results in the formation of a connected fracture network spanning from the surface through the seam goaf linkage. Implementing goaf backfilling measures significantly reduces the vertical settlement of the overburden, prevents the formation of through-layer air leakage channels, and effectively mitigates interlayer air leakage problems during lower-seam mining.

With the rapid development of information technology, the industrial boundary is gradually blurred, and industrial cross-border integration brings new impetus for innovation development and value co-creation. High-tech industrial parks are characterized by industrial diversification, but few studies have analyzed how industrial integration in high-tech parks enhances the value creation of the entire high-tech park from a value perspective. In this study, we build a value network model of the Beijing Economic-Technological Development Area (BDA) based on grounded theory research methods to explore the mechanism of value co-creation among industrial chains in the BDA. Additionally, we found that the communication network infrastructure represented by 5G, the Internet of Things, and the Industrial Internet, the new technology infrastructure represented by artificial intelligence and blockchain, and the computing infrastructure represented by the data center in BDA are integrated with the leading industries, which improves the value of the industry and promotes the digitalization, networking, and intelligent transformation and upgrading of the industry. Contributions for future research are presented.
