Regional balance has an important role in driving the sustainable development of the entire society. The fast, ever-increasing urbanization advances are widening the gap between urban and rural areas, which is an ongoing global problem attracting much attention all over the world. Currently, balanced development occupies the highest priority in social development goals in the Chinese society. It aims at driving sustainable development in rural areas and promoting the urban–rural synergistic development to establish a balanced relationship. In this study, we consider the Zhejiang Province as an example and explore the synergy of the sustainable development of the traditional village cultural landscape based on the balanced development index. Based on the growth synergy model and the fractal aggregation dimension model of the complexity theory, this study discusses the overall characteristics of growth and aggregation synergies of the cultural landscape in traditional villages in the Zhejiang Province. We propose the synergistic activation path for the sustainable development of the cultural landscape in traditional villages under the perspective of “cultural balance” in three aspects: space, society, and industry, with a view to provide a theoretical basis and guiding suggestions for promoting sustainable and regional balanced development of villages.
