Abstract

Purpose - This study evaluates the technical efficiency and productivity changes in the integrated steel plants in India over a period of five years. Design/methodology/approach - Since this evaluation of integrated steel plants needs consideration of multiple input and output factors, Data Envelopment Analysis (DEA) has been employed including bootstrapping (to account for statistical noise) to evaluate the relative efficiency of the steel manufacturing units. The efficiency and Malmquist productivity indices of a sample of 10 integrated steel plants producing around 55% of the industry's output were determined for the period 2008-13. The results of these changes were further categorized according to the management control, route followed to produce crude steel, size and age of these steel plants, for gaining insights. Findings - The study finds that private sector steel plants with larger capacity and which have adopted the latest and most modern technologies are more efficient and productive over the study period. Practical implications - Public sector steel plants should therefore be provided with more autonomy and delegation of power and should be more agile in responding to market requirements as well as increasing their installed capacities to be competitive in technical efficiency and productivity as well as profitability in the long term to ensure sustainable achievements. Originality/values – Productivity changes over time, both with respect to technological and efficiency changes, for the Indian integrated steel plants producing comparable products using DEA

7. Conclusions

Steel is crucial to the development of any modern economy and is considered to be the backbone of human civilization. The level of per capita consumption of steel is treated as an important index of the level of socio-economic development and living standards of the people in any country. All major industrial economies are characterized by the existence of a strong steel industry and the growth of many of these economies has been largely shaped by the strength of their steel industries in their initial stages of development. India’s economic growth is contingent upon the growth of the Indian steel industry. India today occupies a central position on the global steel map, with the establishment of new state-ofthe-art steel mills, acquisition of global scale capacities by players, continuous modernization and up gradation of older plants, improving energy efficiency and backward integration into global raw material sources. With the Indian economy poised for its next wave of growth under the reforms being unleashed in the last few years, there is tremendous opportunity for the Indian steel industry to prosper and grow exponentially.
