Nowadays, the corporate sector plays an important role in the overall economic development even for developing and underdeveloped economies. For example, the corporate sector in India has been witnessing substantial growth specially after 1980s in terms of number of firms and size of paid-up capital. The corporate sector of India has also played a progressive role in building fixed capital, generating employment, discovering new technology, raw-materials and markets, and widely catered the needs of the consumers. This became more prominent after 1991 when the country adopted economic liberalization and accorded a greater role than earlier to the corporate sector in the overall growth process of the economy. The book mainly examines the dynamics of inter-relationship between the firm size, growth and profitability of 164 Indian companies comprising of 13 industries listed in different indices of NSE of India during the post-liberalization period. This book will be useful to professionals of corporate sector, practitioners, policy makers, NGOs and also for the teachers, researchers and students of economics, finance, management and other social sciences.
