The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption ...

Inflows of foreign direct investment generate externalities that spill over to domestic firms and raise their productivity. This article examines the extent of spillover effects of foreign direct investment for firms in the highly disaggregated garment (ISIC 3221) and electronics industries (ISIC 3832) in Indonesia. Both are export-intensive industries, but differ greatly in technological sophi...

Although precipitation interannual variability is projected to increase due to climate change, effects of changes in precipitation variance have received considerable less attention than effects of changes in the mean state of climate. Interannual precipitation variability effects on functional diversity and its consequences for ecosystem functioning are assessed here using a 6-year rainfall ma...

BACKGROUND Standardized methodologies for assessing economic burden of injury at the national or international level do not exist. OBJECTIVE To measure national incidence, medical costs, and productivity losses of medically treated injuries using the most recent data available in the United States, as a case study for similarly developed countries undertaking economic burden analyses. METHO...

JEL Bibliographic Code O15, O18, O47, O53 We postulate that inferior factor productivity in China’s noncoastal provinces is a principal reason for their lower economic growth despite high investment rates relative to coastal provinces. Using the residual from a fixed-effect Solow growth model for the years 1978-93, we find that TFP is roughly twice as high in the coastal provinces. We estimate ...

A standard assumption in integrated assessment models of climate change is that population and productivity are growing, but at a decreasing rate. We explore the signi cance of the assumption of population and productivity growth for greenhouse gas abatement. After all, there has been no long run slow down in the growth of productivity over the past few centuries, and the rate of population gro...

In this paper, periodic force operation of a wastewater treatment process has been studied for the improved process performance. A previously developed dynamic model for the process is used to conduct the performance analysis. The static version of the model was utilized first to determine the optimal productivity conditions for the process. Then, feed flow rate in terms of dilution rate i.e. (...

Monthly mean global green leaf area and photosynthetically active radiation estimated from observations made from several geostationary and polar orbiting satellites were used to estimate potential, (i.e., unstressed) gross primary productivity of terrestrial vegetation from 1982 to 1990. Mean annual gross primary productivity was estimated to be about 179.9 q1.6 Pg C (1 Pg = 1015 g)o Grasses a...

Productivity and Trade Orientation in UK Manufacturing Within a structural model we explicitly allow for the trade orientation of companies to estimate productivity dynamics within 4-digit UK manufacturing industries. We use the FAME data on UK companies over the period 1994-2003. Following Ackerberg et al. (2005) we adjust the algorithm in Olley and Pakes (1996) by augmenting investment and ex...

since the difference in productivity growth rates in different provinces is a result of regional inequality, efficiency criteria in the development of regional-scale agricultural activities is beneficial. therefore it is important that long-term movements in the provinces to identify differences in productivity levels to take effective measures such as investment more in infrastructure, researc...
