摘要
本研究试图考察印度制药业不同规模企业的全要素生产率(TFP),并找出造成全要素生产率变化的因素。研究使用了从 Prowess IQ 数据库获取的 1995-1996 年至 2019-2020 年期间的二手数据,并采用了基于柯布-道格拉斯生产函数估计的参数方法来衡量生产率。分析结果表明,印度制药公司的整体生产率在获得专利后的几年里有所提高。对不同规模企业的全要素生产率进行比较后发现,在专利前和专利后时期,大型企业的生产率都高于中型和小型企业。对全要素生产率增长的估算表明,在专利前时期,所有企业,无论规模大小,都出现了负增长。然而,在专利申请后的几年里,所有企业的增长率都出现了正增长。计量经济学研究表明,产业集中度、企业年龄、企业规模、资本密集度、研发密集度、出口密集度、进口原材料密集度和利润密集度是对企业生产率有显著影响的重要变量,尽管它们的影响方向和影响强度各不相同。
Firm-level productivity and its determinants in the Indian pharmaceutical industry
This study attempts to examine the total factor productivity (TFP) of Indian pharmaceutical industry across different sizes of firms, and to identify the factors responsible for TFP variation. The study uses secondary data accessed from the Prowess IQ database for the period from 1995–1996 to 2019–2020, and employs parametric approach based on the estimation of the Cobb–Douglas production function to measure productivity. The analysis reveals that the overall productivity of Indian pharmaceutical firms has increased during the post-patent years. Comparison of TFP across different sizes of firms reveals that in both the pre-and post-patent periods, large firms exhibit higher productivity than their medium and smaller counterparts. Estimation of TFP growth shows that during the pre-patent period, all firms, irrespective of their sizes, have recorded negative growth rates. However, a positive turnaround is observed in the growth rates of all firms during the post-patent years. Econometric exercise shows that industrial concentration, age of the firm, firm-size, capital intensity, R&D intensity, export intensity, imported raw materials intensity, and profit intensity are the important variables exercising a significant influence on firm productivity, though their direction and strength of influence differ.
期刊介绍:
The aim of the Journal, Decision, is to publish qualitative, quantitative, survey-based, simulation-based research articles at the national and sub-national levels. While there is no stated regional focus of the journal, we are more interested in examining if and how individuals, firms and governments in emerging economies may make decisions differently. Published for the management scholars, business executives and managers, the Journal aims to advance the management research by publishing empirically and theoretically grounded articles in management decision making process. The Editors aim to provide an efficient and high-quality review process to the authors.
The Journal accepts submissions in several formats such as original research papers, case studies, review articles and book reviews (book reviews are only by invitation).
The Journal welcomes research-based, original and insightful articles on organizational, individual, socio-economic-political, environmental decision making with relevance to theory and practice of business. It also focusses on the managerial decision-making challenges in private, public, private-public partnership and non-profit organizations. The Journal also encourages case studies that provide a rich description of the business or societal contexts in managerial decision-making process including areas – but not limited to – conflict over natural resources, product innovation and copyright laws, legislative or policy change, socio-technical embedding of financial markets, particularly in developing economy, an ethnographic understanding of relations at a workplace, or social network in marketing management, etc.
