Carbon Markets and Green Innovation: Path‐Dependent Firm Responses to Emissions Trading

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper identifies a dynamic boundary condition of the Porter hypothesis by examining how firms' pre‐existing innovation trajectories shape regulatory‐induced green innovation within the context of a market‐based carbon policy. Building on path dependency theory, we argue that firms' responses to environmental regulation are contingent on ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Rethinking a positive‐sum game: US FDI location decisions in the presence of Chinese FDI

Global Strategy Journal, EarlyView.
Abstract Research Summary This study examines how rising Chinese outbound foreign direct investment (OFDI) in third‐country markets shapes US MNEs' foreign direct investment location decisions amid escalating US–China geopolitical rivalry. US firms initially benefit from complementary co‐location dynamics, as Chinese OFDI—particularly in infrastructure—
