The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.     

基于ANSYS Workbench电加热支架结构运输断裂分析

随着我国数据中心制冷设备制造技术不断发展,对设备结构的设计质量及可靠性要求越来越高.为改善某项目电加热支架结构运输后的断裂问题,利用ANSYS有限元分析方法对加热器支架运输断裂问题进行静力学、随机振动分析,确认电加热支架结构应力分布、安全系数薄弱位置,并通过对电加热支架结构"几型"的设计优化,在多个项目中应用且运输到西北地区后观察均未出现振动断裂现象,取得良好的改善效果.

Fiscal decentralization, revenue and expenditure assignments, and growth in China

Theory suggests that a close match between revenue and expenditure assignments at sub-national levels benefits allocative efficiency, and hence economic growth. That is, a convergence of revenue and expenditure assignments at sub-national levels of government should, according to the theory, be positively associated with a higher growth rate. In the case of China, this paper shows, divergence, rather than convergence, in revenue and expenditures at the sub-national level of government is associated with higher rates of growth. A panel dataset for 30 provinces in China is used to examine the relationship between fiscal decentralization and economic growth over two phases of fiscal decentralization in China: (1) 1979–1993 under the fiscal contract system, and (2) 1994–1999 under the tax assignment system. The seeming contradiction between the theory and evidence in the China case is reconciled by taking into account the institutional arrangements that prevailed during the two phases of fiscal decentralization, in particular the inconsistency between the assumptions of the theory of fiscal decentralization and the institutional reality of China.     

试论城市建设与水土保持生态环境建设

随着国民经济转型的发展,城市化进程加快,城市水土流失也将越来越严重。搞好城市建设与水土保持生态环境建设的关系,尤为重要。城市建设必须接受《水土保持法》的制约;应与自然景观相协调,维护生物物种的多样性;必须维护河流水系形态的平衡;城市建设应与城郊防护林体系及城市绿地紧密结合;田园城市模式应成为新城区的主体;城市建设要保护好黑土地的水土保持生态环境。

Boussinesq方程的永形波的级数解

对于用层平均速度势(或速度)与波高给出的非线性等水深Boussinesq方程,与KdV方程一样,存在两类永形波—孤立波和周期波。不同的是,对于Boussinesq方程,孤立波和周期波一样,是以反函数的积分形式给出的,这在使用上是不方便的。本文对这两类波,分别给出了相应的级数形式的正函数解。对于孤立波,级数的收敛速度是十分快的,且文中还给出了一个具有高精度的十分简单的近似解,对于周期波,只要有关参数选得合适,解的收敛速度也是相当快的。这就有效地克服了反函数形式解在使用上的不方便。     

The approach to transforming the traditional agricultural economy: a research on the multiple paths of poverty alleviation and transformation in rural China

Transforming a traditional agricultural economy into a modern economy is one of the main themes in economic development. Through theoretical and empirical analysis, this paper finds out that the key to transformation is to raise the economic value of people, to improve human capital investment and to match the stocks of physical and human capital. China’s rural economy is on the edge of economic take-off, and different zones may pursue different paths for transformation. The source of rural poverty is not the scarcity of income or consumption, but the deficiency of education, social security, medical care and economic opportunity, which we define as “capability poverty”. __________ Translated from The Journal of World Economy (世界经济), 2005,(2) (in Chinese)     

城市堤防工程设计的体会与思考

在堤防建设中,城市堤防的新建和加固占有相当比例。建设城市堤防工程,不能与城市总体建设截然分开。山丘区城市的堤防设计中存在堤防建设与城市建设之间的矛盾,设计中应根据各堤防的实际情况,采用合理的设计方案,并结合采用适宜的景观设计,较好地解决这些矛盾。
