The Higher Land Prices, the Worse Emission Performance? Theory and Evidence

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
This study investigates whether high land prices in China have worsened polluting enterprises’ emission performance. Our model confirms that increases in pollution intensity led by rising land prices are the result of fewer resources being directed to abatement investments, which corresponds to smaller declines in emissions versus output.

Assessment of Life Safety Risk in Building Fires With an Integrated Fire and Evacuation Model

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
This paper presents an integrated simulation methodology that combines fire hazard modeling with pedestrian evacuation analysis to evaluate how tenability conditions affect occupant egress. In the proposed approach, fire scenarios representative of leisure and spa resorts are modeled using the Fire Dynamics Simulator (FDS).

Forecasting Stock Return Based on the Multifactor Dynamic Attention Network

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
The application of multifactor models for forecasting stock returns has become a relatively mature practice in the financial field. The assumption of no collinearity among factors in some existing research may lead to the loss of stock information. In order to address this issue, a novel multifactor model, the multifactor dynamic attention network ...

Stock Market Liberalization and Capital Market Informational Efficiency: Evidence From the Mainland China–Hong Kong Stock Connect

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
China’s stock market liberalization, exemplified by the Mainland China–Hong Kong Stock Connect (MCHKSC), presents a pivotal setting to examine whether opening markets enhances capital market informational efficiency. Exploiting the quasi‐natural experiment of the MCHKSC’s phased rollout, we employ a staggered difference‐in‐differences design to ...
