绩效视角下中国生态文明建设的时空交互特征及耦合关系

从绩效视角研究生态文明建设的时空动态特征和耦合关系有助于理解生态文明建设的空间差异机理,对实现生态文明建设提质增效具有重要意义。运用非参数Kernel密度估计、LISA时间路径、时空跃迁和重心耦合等方法,从业绩和效率视角探究了2005-2017年中国生态文明建设的时空动态格局及其耦合关系。研究发现：（1）生态文明建设业绩和效率的整体空间非均衡性差异明显,生态文明建设业绩呈"单峰"演变分布特征,而生态文明建设效率呈明显的"双峰"分布特征。（2）生态文明建设业绩和效率的时空格局动态变迁路径差异显著,生态文明建设业绩局部空间结构和空间依赖方向上稳定性较强,具有协同与竞争并存的特征;而生态文明建设效率的局部空间结构和空间依赖方向上的波动性较生态文明建设业绩强,形成竞争主导型格局。（3）生态文明建设业绩存在路径依赖和空间锁定特征,而生态文明建设效率的类型转移相对活跃,路径依赖和空间锁定特征较生态文明建设业绩弱。（4）生态文明建设业绩和效率的重心趋于集聚,空间耦合关系不断增强。高绩高效型主要分布在东部沿海地区,青海、内蒙古和宁夏为稳定低绩高效型,而其他中西部省域多属低绩低效型。

Spatio-temporal interaction characteristics and coupling relationship of eco-civilization construction in China from the perspective of performance

It is paramount to study spatio-temporal dynamics pattern and coupling relationship of eco-civilization construction from the perspective of performance, which plays a fundamental role for improving quality and efficiency of eco-civilization construction. This paper used the methods of Kernel density estimation, Exploratory spatial data analysis (ESDA), LISA Time Path and Centre-of-Gravity Path to analyze the space-time dynamism and spatial coupling of eco-civilization construction pattern from the perspective of performance and efficiency from 2005 to 2017 in China. Results showed that:(1) There is a significant difference in the overall spatial non-equilibrium between eco-civilization construction performance and efficiency. The performance of eco-civilization construction shows an obvious "single peak" evolution distribution, while the eco-civilization construction efficiency shows an obvious "double peak" distribution. (2) The spatio- temporal pattern of eco-civilization construction performance and efficiency has obvious difference in dynamic change paths. The local spatial structure and spatial dependence direction of eco-civilization performance construction have strong stability, and it presents the characteristics of synergy and competition, while the volatility in local spatial structure and spatial dependence direction of eco-civilization construction efficiency are stronger than the eco-civilization construction performance, forming a competitive-oriented pattern. (3) The spatial association model and spatial transfer inertia of eco-civilization construction performance are characterized by a path dependence and spatial locking characteristics, and the spatial transfer inertia is strong, while the local spatial structure of eco-civilization construction efficiency is unstable-the changes between different types were active and frequent. (4) Significant spatial coupling characteristics between the eco-civilization construction performance and efficiency exist, and the spatial coupling relationship is continuously enhanced. The provinces with High performing-High efficiency are mainly distributed in the eastern coastal provinces. Qinghai, Inner Mongolia and Ningxia are stable Low performing-High-efficiency provinces. The other central and western provinces are Low performing-Low efficient provinces.
