Abstract
This paper aims to address the issue of evaluating watershed environmental efficiency with ecological compensation. One of the main objectives is the dynamic assessment of cross-section efficiency. The first transboundary watershed ecological compensation pilot of Xin’an river basin serves as the case study, and stochastic frontier analysis (SFA) is adopted as the main evaluation method. Furthermore, the efficiency is estimated by the data envelopment analysis (DEA) approach. The results validate that SFA can be used as an effective method on such issues by comparing it with the benchmark and the result of DEA, which proves the feasibility of our research methodology. The other purpose is to investigate the factors affecting environmental efficiency. This paper explores the relationship between environmental efficiency with 21 pollutant emission factors as well as the correlation between environmental efficiency and five macro factors of economic development, industrial structure, population density, degree of environmental protection, and natural environment. Finally, suggestions are provided for future improvement. This paper therefore presents a comprehensive reference analysis that contributes to facilitating balanced regional development and environmental conservation in the future.

Principal Component Analysis (PCA) can be used for data compression and data preprocessing by combining potentially high-dimensional variables into linearly independent low-dimensional variables, which are called principal components
Summary
The problem of environmental contamination has become progressively prominent all over the world. Securing ecosystem services is regarded as one of the fundamental challenges facing humanity [1]. The main reason for such phenomena is the side effects of rapid industrial development. As a country that has had remarkable development, China is no exception. China’s extensive economy mainly relied on resource utilization, which led to economic development accompanied by serious pollution problems. In response to this environmental challenge, policies and activities are implemented in various ways throughout the country. Ecological compensation, as a promising mechanism to coordinate economy and environment, is being rapidly employed in China
