Abstract
Stereolithography (SL) is a kind of rapid prototyping technology which uses the laminate manufacturing to fabricate parts. With the development of RP, some new RP processes have boomed rapidly. Compact prototyping system (CPS) is a kind of novel stereolithography method which utilizes conventional UV light as the light source. After transmitting by optic fiber and focusing through lens set, the light is intensified and can be used to cure the photopolymer. Compared with the laser SL prototyping apparatus, this apparatus has unique characteristics on its driving system and light path system. Discusses the characteristics and corresponding consequences of the driving system and light path system, and analyzes the light energy distribution and the corresponding line shapes. Since each layer is constructed from a serial of lines, the scanning parameters, especially scanning speed and hatch gap, will influence the overall light intensity which determines the layer thickness, section shape and ultimately the prototyping accuracy. The driving system, due to the non‐uniform moving speeds, could cause the shape error of the lines. A light shutter, keeping the light only illuminating on resin surface within given curing areas, is employed to solve this deficiency.

Abstract
This paper tests the pollution haven hypothesis by examining the relationship between environmental regulation and foreign investment with consideration of the role of corporate social responsibility, which has so far been neglected. Using multinationals’ investment data from China, our results in general support the pollution haven hypothesis that less stringent environmental regulation is more attractive for multinationals to invest in China, but high social responsibility can counteract attractiveness of weak environmental regulation.

Abstract
The issue of environmental regulation and productivity has received increasing attention among academics, but little research has focused on Chinese firms despite the serious state of pollution in China. This study aimed to fill that gap. Analyzing a sample of firms from 12 Chinese cities, we found that environmental regulation could improve firm productivity, but the responses to environmental regulation differed across industry sectors, firm sizes, and locations. In this paper, we discuss the implications of these responses toward the environmental policy in China.

Abstract
Purpose
This paper aims to conduct a comparative study between the historical development of corporate social responsibility (CSR) in both the USA and China. It is motivated by the phenomenon that CSR is developing in two different directions (global vs local).
Design/methodology/approach
A comparative study on sustainability-linked compensation illustrates how CSR in the USA is driven by firm-level economic decisions, in which the manifestations of CSR are usually those which prove to be the most profitable financially. Moreover, a case analysis on the green bond market in China contrarily illustrates how CSR in China is usually based more on alignment with top-down, state-led initiatives in which the state directs the ways in which CSR is manifested.
Findings
This paper reveals that despite globalizing trends are attempting to unify definitions of CSR, they inevitably become localized to fit the societal needs in which they are located.
Originality/value
By understanding how CSR development in these two countries has changed over time, this paper shows that future developments in CSR will likely be influenced more by local practices than by converging global forces.
