Abstract

This paper aims to analyze efficiency of sustainable development of foreign trade in eastern China to reduce the input while maintaining the current output level. This paper adopts relevant input-output indicators of 11 provinces in eastern China from 2016 to 2020 and uses DEA to measure comprehensive efficiency, pure technical efficiency, and scale efficiency from the input perspective. Malmquist index was used to calculate MPI. As a result, from 2016 to 2020, the MPI of all provinces in eastern China was 1.035, higher than 1, and the net technology efficiency was 0.911, lower than 1. Overall, the average technological progress index increased 4.5% to 1.045. It can be seen that the sustainable development efficiency of foreign trade has an overall influence on comprehensive efficiency, net technology efficiency, and scale efficiency. The efficiency of sustainable development of foreign trade in eastern China is mainly limited by its scale. The improvement of MPI in the eastern Region mainly benefits from technological progress. For provinces affected by internal factors, it is suggested to strengthen internal coordination. For provinces affected by external factors, it is suggested to respond appropriately to external factors.

본 논문은 현재 생산량을 유지하면서 투입량을 줄이기 위해 중국 동부지역의 대외무역 지속가능 발전의 효율성을 분석하는 것을 목적으로 한다. 2016년부터 2020년까지 중국 동부 11개 성 및 도시의 관련 입출력 지표를 채택하고 DEA모형을 이용하여 종합적 효율성, 순기술 효율성 및 규모 효율성을 측정하였다. MPI 산정에 Malmquist 지수를 사용한 결과 2016년부터 2020년까지 중국 동부 전 성의 MPI는 1.035로 1보다 높았고, 순기술 효율성은 0.911로 1보다 낮았다. 전체적으로 평균 기술진보지수는 4.045로 4.5% 증가했다. 대외무역의 지속 가능한 발전 효율성은 종합적 효율성, 순기술 효율성, 규모 효율성에 전반적으로 영향을 미치고 있음을 알 수 있다. 대외무역의 지속 가능한 발전 효율성은 규모에 의해 주로 제한을 받았다. 총요인 생산성 향상은 주로 기술적 진보로 부터 효과를 얻는 것으로 나타났다. 내부요소의 영향을 받는 성들에 대해서는 내부조률을 강화하여야 한다. 외부요인의 영향을 받은 성은 외부요인에 대비해야 한다.
