ASEAN Cultural Industry Cluster Evolution Prediction and Policy Simulation Using Spatial-Temporal Graph Convolutional Networks

The Association of Southeast Asian Nations (ASEAN) cultural industry has emerged as a strategic pillar in regional economic integration, with the sector's contribution to GDP increasing from 4.2% in 2015 to 6.8% in 2023. This rapid growth has catalyzed the formation of 89 city-level cultural industry clusters across the region, encompassing creative hubs in Singapore, Bangkok, Jakarta, and emerging centers in Vietnam and the Philippines. However, this expansion exhibits significant spatial heterogeneity: while metropolitan clusters demonstrate annual growth rates exceeding 15%, peripheral regions lag at 3-5%, creating pronounced development imbalances that challenge policymakers' efforts to achieve equitable regional growth. Accurate prediction of cultural industry cluster evolution is critical for evidence-based policy formulation, yet existing methodologies face fundamental limitations. Traditional econometric approaches such as Vector Autoregression (VAR) and Autoregressive Integrated Moving Average (ARIMA) models treat spatial units as independent entities, failing to capture the intricate interdependencies between geographically proximate or economically linked clusters [1]. Recent machine learning attempts using Long Short-Term Memory (LSTM) networks have improved temporal modeling but remain inadequate in representing spatial dependencies and policy intervention effects [2]. Critically, no existing framework provides differentiable mechanisms to simulate discrete policy variables—such as tax incentives, subsidies, and land-use preferences—limiting their utility for scenario-based policy analysis. This research addresses these gaps by developing a Spatial-Temporal Graph Convolutional Network (ST-GCN) architecture specifically designed for cultural industry cluster forecasting. Our model represents the 89 ASEAN clusters as graph nodes, with edge weights encoding both geographical proximity (via Gaussian kernel functions) and economic linkage strength (derived from trade flows and cross-border investment data). The core innovation lies in the Policy Intervention Embedding Module, which transforms discrete policy variables into continuous, differentiable feature vectors through learnable embedding layers combined with Gumbel-Softmax relaxation. This enables gradient-based optimization and counterfactual policy simulation within a unified deep learning framework.
