摘要

经济文献表明，创新与产品市场竞争之间存在倒 U 型关系。现有的实证研究在估算这两个变量之间的关系时假设了二次函数形式。本文利用印度制造业的数据，采用半参数方法检验了 "倒 U 型 "假设，而无需先验地假设函数形式。估计结果表明，这种关系的函数形式取决于模型中产品市场竞争指标的选择。当产品市场竞争被定义为总体价格竞争时，经验证据证实了倒 U 型假说。这意味着随着价格竞争的加剧，逃避竞争和熊彼得效应都会出现。然而，当产品市场竞争被定义为国内竞争时，只观察到逃避竞争效应。JEL Codes：L10, L60, O30, O33, F10

Investments in Innovations and Market Structure: A Semi-parametric Approach

The economic literature suggests that there is an inverted-U type of relationship between innovation and product market competition. Existing empirical studies assume a quadratic functional form while estimating the relationship between the two variables. Using data on the Indian manufacturing industry, this article contributes by using a semi-parametric approach to test the ‘Inverted-U’ hypothesis without assuming a priori functional form. The estimation results suggest that the functional form of the relationship is contingent upon the choice of product market competition indicator in the model. When product market competition is defined as overall price competition, the empirical evidence confirms the inverted-U hypothesis. This implies that both escape competition and the Schumpeterian effect are observed as price competition increases. However, when product market competition is defined as domestic competition, only the escape competition effect is observed. JEL Codes: L10, L60, O30, O33, F10

期刊介绍： The South Asian nations have progressively liberalized their economies in recent years in an effort to integrate with the world economy. They have also taken steps to enhance multilateral and regional economic integration. Even though the South Asian economies have grown at an average rate of more than 5 per cent over the last few years, roughly 40 per cent of their people still live below the poverty line. Hence, the South Asian region continues to face many challenges of economic and social development. The South Asia Economic Journal (SAEJ) is designed as a forum for informed debate on these issues, which are of vital importance to the people of the region who comprise one-sixth of the world’s population. The peer-reviewed journal is devoted to economic analysis and policy options aimed at promoting cooperation among the countries comprising South Asia. It also discusses South Asia’s position on global economic issues, its relations with other regional groupings and its response to global developments. We also welcome contributions to inter-disciplinary analysis on South Asia. As a refereed journal, SAEJ carries articles by scholars, economic commentators,policy-makers and officials, from both the private and public sectors. Our aim is to create a vibrant research space to explore the multidimensional economic issues of concern to scholars working on South Asia. Among the issues debated in relation to South Asia are: - the implications of global economic trends; - the issues and challenges by WTO; - approaches to industrialization and development; - the role of regional institutions such as the SAARC; - the relationship between SAARC and other regional economic groupings such as ASEAN; - the implications of economic liberalization for trade and investment in the region; - new initiatives that can be launched to enhance economic cooperation among the South Asian countries both on a bilateral and a regional basis.
