This chapter looks toward the future of urban green space equity research, noting that while significant progress has been made, there remains ample room for exploration in both theory and practice. At the research scale, the future focus should be on establishing more dynamic and refined assessment models that span the global, city, and individual levels, particularly to deeply uncover the core mechanisms by which daily mobility leads to the “polarization” or “averaging” of green exposure. More importantly, future breakthroughs will stem from the interdisciplinary fusion of equity, health, and ecology. This requires a paradigm shift from static, singular evaluations to dynamic, complex-systems analysis, taking into account the health benefits, climate regulation, and other ecological functions of green space, as well as their differential impacts on various populations. Long-term tracking studies are needed to assess the potential positive effects of green space development (such as improved health) and its potential negative consequences (such as green gentrification). Ultimately, the goal of this research is to drive practical change. Through the collaborative participation of government, academia, and communities, the needs of marginalized groups can be integrated into planning decisions, making green space development a true tool for promoting social equity, public health, and ecological sustainability.
