In the context of supply-side structural reform (SSSR), the central government pays more attention to high-quality economic growth. Technological innovation, standards, and quality (TSQ) are the core elements of the SSSR. Therefore, it is essential to understand the coupling relationship between TSQ subsystems and explore its economic growth effect. This study examines the coupling relationship between technological innovation, quality improvement variables, and standard settings for the listed companies in China during 2007–2016. This study assesses the coupling relationship and development difference among TSQ subsystems by developing a coupling coordination degree model. The findings show that the quality subsystem is the collaborative shortboard subsystem, and the standard subsystem plays a role in three subsystems. Moreover, ordered optimization in coupling coordination for each subsystem’s pair, TSQ subsystems achieve high-level internal coordination and resist coupling. However, the speed of the coupling among I–S–Q subsystems is less in any two subsystems. There is a positive link between the coupling coordination degree of TSQ subsystems and economic growth. Still, the effect of the coupling relationship of I–S–Q subsystems with economic growth is more significant. This study offers support for managers, policymakers, and government officials for better policies to optimize the supply structure, enhanced the manufacturing industry, and promote the economic growth of emerging economies.

Thin‐walled structures are used extensively in the passive safety of vehicles to absorb energy. The thin‐walled tube is already a traditional structure with excellent energy absorption. Negative Poisson's ratio (NPR) structures produce an inward concentration to increase the stiffness of the structure during axial compression. The concept of fluctuation of crushing force (FoCF) is introduced herein to evaluate this new energy‐absorbing box as an energy‐absorbing device based on the traditional energy absorption evaluation index. Based on experimental validation, a finite‐element model is developed that can accurately predict the crashworthiness of the double‐V NPR‐filled square tube (DVFST). The following parameters, such as out‐of‐plane thickness, meta‐cell half‐width beam thickness, and beam angle tube thickness, are conducted to assess the crashworthiness of the DVFST structure. The first thing that should be considered in the design of the DVFST structure is the half‐width of the cell, followed by the angle of the long beam, and then the relative wall thickness of the long and short beams. The DVFST structure has the potential to become an excellent energy‐absorbing device by adjusting its parameters.
