'Green chasm' in clean-tech for air pollution: Patent evidence of a long innovation cycle and a technological level gap

The dual challenges of economic development and environment conservation tend to be a lopsided discussion for developing countries. Compared with the concept of poverty trap or middle-income trap for economic development. The conceptualization of the difficulties and obstacles that developing countries are facing for environment conservation is rare to find. This study is one of efforts to balancing out the discussion by borrowing the concept of Moore's chasm. The study articulates the concept of green chasm to explain the discontinuation of latecomer's catch-up and enhanced forerunner's enduring leadership. Through the patent analysis of clean-tech for air pollution, the study found a long innovation Technological Innovation Systems (TIS) life cycle in clean-tech and a large technological gap in the catch-up cycle, which often lead the frustration of latecomer's experience to develop green innovation. This finding has led the policy proposal for overcoming green chasm. By classifying the window of opportunity for catch-up into six TIS functions and then by interpreting it as a transnational dimension, the following policies are suggested; the application of compulsory license, antitrust restriction, and export license easing measures for clean-tech.
