社会治理创新:对行业治理的若干思考

经济社会转轨呼唤社会治理创新,实行行业治理将是我国经济社会发展的必然选择,也是实现我国国民经济高效运行和资源有效配置的必然选择。实行行业治理必须加强对行业和行业协会的调查研究与理论探讨,必须准确厘清并把握其基本内涵,在结合我国现实国情的基础上,从行业协会建设、政府职能转变、法制化建设以及行业治理的运行机制的创建等方面,努力探讨和构建符合我国国情的行业治理结构。

The impact of the Internet on human activity–travel patterns: analysis of gender differences using multi-group structural equation models

The widespread use of the Internet for conducting various types of activities may be leading to considerable change in people’s activity–travel patterns. Past studies, however, have left many issues unaddressed. Using an Internet-activity diary dataset and multi-group structural equation modeling, this study examines the complex interactions between different types of Internet and physical activities, with a special focus on gender differences and Internet maintenance and leisure activities. The results indicate that the impacts of Internet activities on people’s activity–travel patterns are significantly different across gender. In general, Internet use for maintenance purposes has a greater impact on women’s activity–travel in the physical world, while Internet use for leisure purposes affects men’s physical activities and travel to a greater extent. Further, breaking Internet activities down into different categories reveals some hidden patterns that would not have been detected if these different types of Internet activities were lumped together as a single category.     

Sales recruiting—A major area of underinvestment

How does a firm decide whether the amount now being spent to generate sales force applicants is too much, not enough, or about right? This question can be answered by using information routinely generated by corporate activities and a relatively straight forward decision theory technique. To illustrate that technique, an analysis was conducted for a hypothetical but by no means atypical firm. The results suggest that many corporations could appreciably increase their overall profitability by spending more on sales force recruitment and selection.     

Targeted poverty investments and economic growth in China

In the mid-1980s, the Chinese government launched its ambitious poor area development policy, which was centered around a series of grant, credit, and Food-for-Work programs. Ironically, for the remainder of the 1980s rural poverty remained at about 90 to 100 million, or approximately 10% of the rural population. The lack of progress cannot necessarily be blamed on ineffective poor area policies, since much of the agricultural economy was mired in a deep recession between the mid-1980s and the early 1990s. By the mid-1990s substantial additional poverty reduction had been achieved. Even in the late-1980s, farmers in many poor counties did better than the national average in terms of income growth. After accounting for the effects of macroeconomic elements, what factors can help explain the differences in performance among poor regions and between poor areas and rich ones? Can part of these differences be accounted for by poor area policies, in general, or by the way local and regional officials allocate their poor area investment funds, in particular?The overall objective of this paper is to analyze the effectiveness of Chinese poor area policy. Specifically, the paper seeks to meet three objectives. First, we want to understand the evolution of poor area policy since the mid-1980s, trying to deduce the true goals of central and regional poor area officials, as well as how these policies have been implemented in the provinces. Next, we want to understand the magnitude and scope of investment into poor areas, and examine if changes in these policies have affected the uses of the investment funds. Finally, we want to determine the effectiveness of the investment of poor area funds, analyzing which types of investments have generated growth, and which ones have not.
