Impact of Growing Income Inequality on Sustainable Development in China: A Provincial-level Analysis
Nico Heerink Ma Jia 《中国人口.资源与环境(英文版)》2006,4(1):23-32
A growing body of literature has documented the rapidly increasing income disparities that accompanied China's economic growth in the 1980s and 1990s, and the driving factors behind this. Growing income inequality in its turn may have important implications for the accumulation of physical capital, human capital, and natural capital and as a consequence for sustainable economic development. The purpose of this paper is to investigate the potential impact of income inequality on savings, human resources and the environment in China. It starts with an overview of the different causal mechanisms through which income inequality may affect the accumulation of physical capital, human capital, and natural capital, and discusses to what extent these causal relationships may be relevant in the case of China. Next, provincial data for the year 2002 are used to explore the relationship between income inequality and different elements of sustainable development in China. It is found that income inequality does not affect aggregate savings levels. Rising inequality, however, contributes to lower health and possibly also to higher fertility levels. It also lowers the use of chemical fertilizers in agriculture and therefore is likely to reduce water pollution. Other types of environmental degradation are not affected. 相似文献

Sexual conflict between mating partners can give rise to strategies that are advantageous for one sex but harmful to the opposite sex. Usually, sperm donors develop (offensive) traits to enhance their chances in sperm competition, while sperm recipients evolve (defensive) traits that allow them to stay in control of who fathers their offspring. Here, we demonstrate that these processes are also at work in simultaneous hermaphrodites. The hermaphroditic earthworm Lumbricus terrestris uses 40 to 44 copulatory setae to pierce into its partner's skin, causing damage and injecting a substance from its setal glands. Experimental injection of the gland substance indicates that a refractory period may be induced. More importantly, removal of the copulatory setae shows that they influence the partner's sperm uptake. When the setae are present, more sperm are taken up and sperm are distributed more equally over the four spermathecae. We interpret this as a strategy that stacks the odds for the donor's sperm in fertilizing cocoons. 相似文献

Congenital hypophosphatasia is an autosomal recessive disorder, which usually has a fatal outcome during the neonatal period. This report presents the prenatal diagnosis of hypophosphatasia at 16 weeks of gestation. The characteristic ultrasonic findings in this abnormality demonstrate the superiority of ultrasound as compared with radiography. 相似文献

A refined exit, voice, loyalty, and neglect (EVLN) typology (Farrell, 1983) was examined. It was argued that the category of voice responses, that is, attempts to improve the situation, should be divided into two forms: considerate voice and aggressive voice. Considerate voice consists of attempts to solve the problem taking into account one's own concerns as well as those of the organization, and aggressive voice consists of efforts to win, without consideration for the concerns of the organization. In line with Farrell (1983), all categories of behavioral responses were assumed to differ on two dimensions, namely, destructive–constructive and active–passive. It was assumed that the responses can be ordered in a circumplex structure. Factor analyses of data from 233 teachers and maternity nurses demonstrated the empirical separability of the five categories of behavioral responses and supported the two‐dimensional structure of the model. Job satisfaction, especially satisfaction with supervision, seemed to promote considerate voice and loyalty (that was relabeled as patience), and suppress exit, aggressive voice, and neglect. Furthermore, the correlations between job satisfaction and the five responses provided additional support for the circumplex structure of the refined model. The pattern of responses runs in the following order: considerate voice, aggressive voice, exit, neglect, patience. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Radial-ray reduction malformations (RRRMs) may occur isolated or in association with other anomalies. The data of seven fetuses born with RRRMs were collected. Six fetuses had associated lethal abnormalities of the central nervous system, urogenital system, and/or heart, detected by ultrasound. In five cases, it was possible to establish the precise diagnosis, enabling an informed prognosis and subsequent genetic counselling. The diagnoses were: Edwards syndrome (n=3), VACTERL association (n=1), and Poland-Moebius-like complex (n= 1). In two cases, a complete diagnosis was not possible because of inadequate evaluation of these fetuses before and/or after birth. A proposal is given for the diagnostic approach for infants with RRRMs detected in the antenatal period by means of ultrasonography. 相似文献
