What is Study on the coupling problem of coordinated development of economy–energy–environment–technology system in Northeast China about?

Under the strategy of “Northeast Revitalizing”, Northeast China must correctly handles the coupling relationship of coordinated development among economy, energy, environment, and technology if it insists on the concept of green development. In this paper, by establishing an appropriate evaluation index system and introducing ”kernel function density” analysis method, the coupling problem and it’s time evolution characteristics of the coordinated development of the economy–energy–environment–technology of Liaoning Province, Jilin Province, Heilongjiang Province and Inner Mongolia Autonomous Region in Northeast China were studied. It was found that the coordination degree of the quaternary systems was between 0.71 and 0.97, and it was good. The development degree was between 0.25 and 0.58, and it was very bad. The ”weakness” of low development degree results in the low coupling degree (between 0.46 and 0.70) of the quaternary system. The coordination degree of the quaternary systems in Northeast China was increasing year by year, and the differences between provinces (regions) were also shrinking. The development degree generally presented ”wave” fluctuation characteristics, and the
