【摘要】:近年來,我國城市化率不斷提高、中小城市在不斷向大城市發(fā)展的同時(shí)有學(xué)者認(rèn)為我國中小城市的數(shù)量規(guī)模不斷減少是一種不穩(wěn)定的狀態(tài),因?yàn)樾〕鞘袛?shù)量的減少并沒有從小城鎮(zhèn)的發(fā)展得到數(shù)量上的補(bǔ)充,所以認(rèn)為我國目前發(fā)展的目標(biāo)應(yīng)該是如何將小城鎮(zhèn)發(fā)展為城市或重點(diǎn)發(fā)展中等城市,而不是繼續(xù)重點(diǎn)發(fā)展大城市。同時(shí)由于"大城市病"的存在,反城市化現(xiàn)象也日益普遍,在美國已經(jīng)成為人民選擇定居的重要考慮因素,大有與城市化勢均力敵的趨勢,使得有學(xué)者認(rèn)為大城市的發(fā)展應(yīng)該得到一定的限制。將逐步對500萬人口以上城市減少建設(shè)用地、劃定永久基本農(nóng)田的做法某種程度上與此觀點(diǎn)具有一致性。對此,本文認(rèn)為小城市的發(fā)展受到多項(xiàng)因素的制約,盲目地發(fā)展只會(huì)出現(xiàn)更多的問題,只有大城市的不斷發(fā)展,才能逐步減少本地條件的制約,充分進(jìn)行資源的整合,從而以一種更穩(wěn)固、健康的方式發(fā)展。.為了研究影響不同類型城市綜合水平的制約因素,選擇更適合重點(diǎn)發(fā)展的城市類型,本文將我國地級以上城市按照綜合指標(biāo)用聚類分析方法分為四類,用因子分析方法得出各城市的綜合因子得分,并以此為被解釋變量對各類型城市作面板回歸討論影響因素在各個(gè)階段對城市的作用,即從綜合水平表現(xiàn)特征與影響因素兩個(gè)方面進(jìn)行對比。最終發(fā)現(xiàn),城市綜合發(fā)展水平越高,會(huì)在更少的方面受到制約,被制約的程度也逐步減小。同時(shí)還發(fā)現(xiàn)城市的發(fā)展過程中符合邊際報(bào)酬先遞增后遞減的規(guī)律,邊際報(bào)酬會(huì)在綜合發(fā)展水平較高的城市類型達(dá)到最大,應(yīng)該得到重點(diǎn)發(fā)展。
[Abstract]:In recent years, the urbanization rate of our country has been increasing, while the small and medium-sized cities are developing to the big cities, some scholars think that the decreasing of the number and scale of the small and medium-sized cities in our country is an unstable state. Because the reduction in the number of small cities has not been supplemented by the number of small towns, it is believed that the goal of our country's current development should be how to develop small towns into cities or focus on developing medium-sized cities. Instead of continuing to focus on developing big cities. At the same time, because of the existence of "the disease of big cities", the phenomenon of anti-urbanization is becoming more and more common. In the United States, it has become an important factor for people to choose to settle down, and there is a tendency to match the trend of urbanization. Some scholars believe that the development of large cities should be limited. The practice of gradually reducing construction land for cities with a population of more than 5 million and delineating permanent basic farmland is somewhat consistent with this view. In view of this, this paper holds that the development of small cities is restricted by many factors, blind development will only lead to more problems, only the continuous development of large cities can gradually reduce the constraints of local conditions and fully integrate resources. To develop in a more stable, healthy way. In order to study the restrictive factors affecting the comprehensive level of different types of cities and select the more suitable urban types for the key development, this paper classifies the cities above the prefectural level into four categories by cluster analysis according to the comprehensive index. By using factor analysis method, the comprehensive factor scores of each city are obtained, which is used as the panel regression of the explained variables to discuss the effect of the influencing factors on the city in each stage. Namely from the comprehensive level performance characteristic and the influence factor two aspects carries on the contrast. Finally, it is found that the higher the level of urban comprehensive development, will be restricted in less aspects, and the extent of constraints is gradually reduced. At the same time, it is found that in the process of urban development, the marginal returns increase first and then decrease, and the marginal returns reach the maximum in the urban types with higher comprehensive development level, which should be developed with emphasis.
