This Study Aims To Analyze The Relative Position Of Each Developing Country, In Terms Of Ecological Efficiency And Effect Of Many Influencing Factors On It. Ecological Efficiency (Relative Resource Intensity) Was Calculated In Terms Of Ecological Footprint Per Unit Of Gdp, And It’s Cross National Variation Is Analyzed. The Stochastic Impact By Regression On Population, Affluence And Technology (Stirpat) Model Was Used As An Analytical Tool To Examine The Effect Of Different Influencing Factors On Relative Resource Intensity, Using The Cross Section Data Of 91 Developing Nations For The Year 2011 And Weighted Least Square Regression Analysis. The Data On Ecological Footprints Was Obtained From Global Footprint Network. The Analysis Shows That The Coefficient Of The Linear Term Of Gdp Per Capita Is Positive And Quadratic Term Of Gdp Per Capita Is Negative And Thus Cross National Ekc Relationship Between Relative Resource Intensity (Ef/gdp) As The Indicator Of Environmental Degradation And The Level Of Economic Development Holds With The Turning Point At Around Us$ 7663. This Finding Suggests That Relative Resource Intensity Is Lower For More Affluent Nations. But, Variation In The Resource Intensity Is Lower At The Higher Affluence Level, Suggesting Lesser Potential For Further Improvement In Ecological Efficiency Performance. Industrialization Has A Negative But Insignificant Effect On Relative Resource Intensity, Indicating That Structural Shift In Developing Countries Don’t Significantly Improves The Ecological Efficiency. And Coefficient Of Population Density Is Negative And Significant. Whereas, Dummy Variable Indicating The Latitude Shows Positive Impact On The Relative Resource Intensity If The Nations Are Located In Arctic Regions And Colder Climate And Negative Impact On The Relative Resource Intensity For Tropical Nations. Overall The Findings Suggest That Eco-efficiency Is Higher In More Affluent Developing Nations But Economic Development And Structural Shift In The Developing Nations Is Insufficient To Achieve Sustainability And May Leads To The Higher Environmental Burden.
