ABSTRACT
This paper develops a unified port performance index (PPI) considering different cargo categories and the multi-dimensional nature of port performance indicators/dimensions. This study has used the quintile method to construct PPI. Further, the PPI obtained from the quintile method is compared with weighted unified index (PPIPCA) using principal component analysis (PCA), extensively used for index development in the literature. A pilot index development is demonstrated using secondary panel data for 12 major Indian ports on five significant dimensions, namely, operations, physical infrastructure, technical infrastructure, finance, and socio-economic. Results show that the JNPT port outperforms all other ports under the container cargo category. Likewise, Kandla port in the liquid port category and Paradip port in the other (dry & break bulk) cargo category are on top. Also, qualitatively similar results and insights are obtained with the PPIPCA. Subsequently, the panel data regression and efficiency analysis are performed to demonstrate the utility of the proposed index. The results affirm that the operations, physical infrastructure, and socio-economic dimensions have a positive and significant impact on port financial performance. The present study operationalises some key unexplored port performance indicators/dimensions that can enable effective decision-making.

Notes
1. CCR model is named after the researchers: Charnes, Cooper, and Rhodes (Citation1978), who introduced the technical efficiency of decision making units (DMUs) based on the constant return to scale assumption.
2. BCC model is named after the researchers: Banker, Charnes, and Cooper (Citation1984), who introduced the pure technical efficiency (PTE) and scale efficiency (SE) of DMUs based on variable return to scale assumption.
3. Scale efficiency = Overall technical efficiency / Pure technical efficiency, or (SE = OTE / PTE).
