Abstract
Production–living–ecological (PLE) space is the basic site of all human activities. The coordinated development of these three spaces is an important prerequisite for achieving sustainable development goals. However, a quantitative assessment of the overall coordination among these three spaces is limited in current research. This paper built an indicator system and a coupling coordination degree model to comprehensively assess the development status of PLE space in China. The statuses of 340 prefecture-level cities across the country from 2005 to 2015 were analyzed. The results showed that the national average first increased from 0.435 in 2005 to 0.452 in 2010 and then dropped to 0.445 in 2015. There was an obvious distribution line between slightly unbalanced cities and moderately balanced cities, close to the famous “Hu Huanyong Line.” Most provincial capital cities were between the slightly unbalanced class and barely balanced class. Only Fuzhou in Fujian Province exceeded the barely balanced class in 2015. This paper provides several references for other developing cities to achieve sustainable and coordinated development.
Highlights
The rapid development of industrialization and urbanization has led to intense competition and conflict between humans and nature, causing a range of issues such as global climate change, the energy crisis, and food security [1], especially in developing counties
It gradually declined, from 0.57 in 2005 to 0.52 in 2015, which shows that the contribution of the economy to the performance of PLE was decreasing
The results show that no cities were seriously unbalanced or superiorly balanced from 2005 to 2015
Summary
The rapid development of industrialization and urbanization has led to intense competition and conflict between humans and nature, causing a range of issues such as global climate change, the energy crisis, and food security [1], especially in developing counties. In 2012, the United Nations created a set of sustainable development goals (SDGs) to respond to the above problems [2]. In 2015, 17 sustainable development goals were officially adopted [3], and the “New Urban Agenda” was released in 2016 [4]. The concept of production–living–ecological (PLE) space was first proposed in the report of the 18th National. Congress of the Communist Party of China. It stressed that “the space for production should be intensive and highly efficient, the living space should be moderately liveable, and the ecological space should be unspoiled and beautiful.”. PLE space was proposed for promoting sustainable economic and social development, which has attracted increasing attention in China.
