The heterogeneities of production technology among provinces in China cause difficulties for unbiased evaluation of energy efficiency. Using meta-frontier data envelopment analysis (DEA) approach, this paper proposes a new method for measuring energy efficiency by considering the “technology...

Waste cooking oil to biodiesel conversion efficiency depends on the recycling mode that is being practiced. The recycling modes in China, the US and Japan can be placed in two categories: third party take-back (TPT) and the biodiesel enterprise take-back (BET). We review the operation mechanisms...

This paper establishes several efficiency models based on environmental production technology, which are capable of integrating undesirable outputs into efficiency evaluation framework. With the proposed efficiency models, we estimate the environmental efficiency, economic efficiency,...

Previous studies involving environmental performance purely focus on analyzing environmental or waste treatment efficiencies. This study combines various aspects of environmental protection and establishes a non-radial network DEA approach to evaluate the performance of an environmental...

We test the determinants of low intra-industrial technology spillovers of foreign direct investment in China’s manufacturing industries with the quantile regression method. Greater technology gap, fewer state-owned enterprises and large-and-medium-size enterprises, and greater industrial...

Torespondto the reduction of greenhouse gas emissions and global warming, this paper investigates the minimal-carbon-footprint time-dependent heterogeneous-fleet vehicle routing problem with alternative paths (MTHVRPP). This finds a route with the smallestcarbon footprint, instead of the...

Converting waste cooking oil into biofuel represents a three-win solution, dealing simultaneously with food security, pollution, and energy security. In this paper, we encode the policy documents of waste cooking oil refining biofuel in China based on content analysis, and explore the related...

Both analysis of international trade and the knowledge resource theory of the firm imply that language skills should play a vital role in exporting. This may be apparent to large multinationals with sites in many different linguistic locations, but we show it is less obvious to smaller...

The relationship among political connections, government subsidies and firm financial performance of wind and solar manufacturing companies is analyzed based on panel data model. The results illustrate that government subsidies, in long and short-terms, have significant positive effects on the...
