Green total factor productivity: A re-examination of quality of growth for provinces in China

In this paper we try to assess the quality of growth for provinces in China over the period of 1997–2015. To do so we calculate a set of Green total factor productivity (or GTFP) indexes by incorporating environmental performance variables at the provincial level. A nonparametric approach (Directional Distance Function a la Chung et al., 1997) is adopted in the estimation. Furthermore, we apply bootstrapping method to correct estimation bias and obtain statistical property of the estimated indexes. The GTFP indexes estimated here demonstrate very different trends from the GDP growth rateand standard TFP indexes ignoring environmental outcomes. For the period of interests, when annual GDP growth rate was very high, no steady growth was found in TFP and GTFP, by contrast. The rankings of provinces differ significantly across measures of GDP growth, TFP and GTFP. In addition, our estimates of GTFP trends are also significantly different from findings by other papers of GTFP estimation (Hu et al., 2008; Wang et al., 2010) without bootstrapping procedure.
