30.5厘米相当于多少寸:题目是“Knowledge Economy”的100字的英文议论文如何写？

Numerous social scientists have documented the transition underway in advanced industrial nations from an economy based on natural resources and physical inputs to one based on intellectual assets. We document this transition with patent data that show marked growth in the stocks of knowledge, and show that this expansion is tied to the development of new industries, such as information and computer technology and biotechnology. The literature on the knowledge economy focuses heavily on knowledge production, however, and attends less to knowledge dissemination and impact. This neglect is unfortunate because a key insight of the productivity debate is that significant gains in productivity are achieved only when new technologies are married to complementary organizational practices. Information technology that facilitates the broad distribution of knowledge is not successfully tethered to a hierarchical system of control. Thus one cannot assume that there is a natural link between knowledge production and flexible work, as new information technologies open up novel possibilities for both discretion and control.

??A focus on knowledge dissemination might also aid the analysis of the skills mismatch thesis. The argument that some classes of workers are highly disadvantaged by technical change is too simple, although clearly older, less-skilled, and minority workers have borne the brunt of the transition to an economy based on intellectual skills. But fine-grained studies of how some less-skilled workers acquired the necessary technical skills to work in new settings are rare, and would be valuable.

??The debate over skills also reveals the relative lack of standard metrics in this area of research. Patents have become an appropriate measure of stocks of knowledge, but we lack any comparable indicators of skills, and too often researchers rely on occupational labels or categories. Yet such labels are easily changed by the stroke of a pen. Consider the thousands of polytechnic schools worldwide that have changed their names to universities. Such "upgrading" is part of a movement to signal membership in a knowledge economy, but accurate substantive measurement of the knowledge economy remains far from resolved. The challenge for social science research is to connect the abundant quantitative indicators with qualitative studies of substantive changes in organizational practices and their outcomes.
