演講摘要 : The environmental Kuznets curve (EKC) hypothesis describes an inverted-U-shaped pollution–income relationship in the long run. To test this hypothesis, this paper selected data on sulfur dioxide (SO2) emissions and GDP series from19 OECD countries during the period 1870–2001.Different from other panel EKC studies that measure average characteristics across nations, this paper performed cointegration tests in individual countries using two time-series models. This paper found that the EKC regressions in most of the countries are spurious from the first-step model of the Engle–Granger two-step procedure, but by incorporating short-run dynamics, the unrestricted ADL-transformed error correction model shows that most countries have stable long-run sulfur–income relationships and support the existence of the EKC phenomenon.
