understanding the rise of china演讲

understanding the rise of china演讲The rise of China is a topic that has captured the attention of the world over the last few decades. Ever since the economic reforms initiated in 1978, China has been on a path of rapid economic growth that has transformed it into a global powerhouse.To understand the rise of China, we need to look at several factors. One of the key drivers of China's growth has been its policy of economic liberalization, which has allowed the country to tap into its vast reserves of human capital and natural resources. This has enabled China to become the world's largest manufacturing base, producing everything from electronics to textiles at a scale that would have been unimaginable just a few decades ago.Another factor that has contributed to China's rise is its focus on infrastructure development. China has invested heavily in building highways, airports, and high-speed rail systems that have not only improved connectivity within the country, but also connected it to the rest of the world.But perhaps the most important factor behind China'srise has been its ability to adapt to changing global conditions. China has been adept at navigating the challenges of globalization, and has been able to position itself as a key player in the global economy.However, China's rise has not been without its challenges. The country still faces significant social, economic, and environmental challenges, which it will need to address if it is to continue on its path of growth anddevelopment.In conclusion, China's rise is a complex and multifaceted phenomenon that has been shaped by a number of factors. It remains to be seen how the country will navigate the challenges that lie ahead, but one thing is clear – the rise of China is a trend that will continue to shape the global order for years to come.。

边际报酬递减规律及其实际应用英文解说稿

Title: The Law of Diminishing Marginal Returns and Its Practical ApplicationsLadies and Gentlemen,Good morning! Today, I would like to discuss an important economic principle known as the Law of Diminishing Marginal Returns and how it shapes our world in various practical ways.The Law of Diminishing Marginal Returns, in essence, states that as the amount of a variable input is increased, while other inputs are held constant, the marginal product of that input will eventually decrease. This principle has profound implications in areas ranging from agriculture to business management and beyond.Let's start with an agricultural example. In farming, farmers initially see significant increases in crop yields when they increase the use of fertilizers or pesticides. However, as the application of these inputs increases, the marginal increase in yield begins to diminish. This is because the soil's capacity to absorb and utilize these inputs is finite. Understanding this law helps farmers optimize their input usage, minimizing waste and environmental impact.Now, let's shift our focus to the business world. In the realm of production, companies often face the challenge of determining theoptimal level of production inputs such as labor and capital. As additional workers or machines are added, the marginal output per unit of input tends to decrease. By understanding this law, businesses can make informed decisions about resource allocation, aiming for efficiency and profitability.The Law of Diminishing Marginal Returns also has implications in marketing and advertising. As companies increase their advertising budget, the marginal increase in sales or brand awareness may diminish over time. This is because consumers become less responsive to repetitive or oversaturated advertising messages. By recognizing this trend, marketers can allocate their budgets more effectively, focusing on strategies that deliver the greatest returns. Moreover, this principle also applies to personal finance and investment decisions. As an investor increases their portfolio, the marginal returns on each additional investment may decrease due to factors such as increased risk or diminishing opportunities forhigh-yield investments. Understanding this law can help investors make more informed decisions about portfolio diversification and risk management.In conclusion, the Law of Diminishing Marginal Returns is a fundamental economic principle that shapes our world in numerousways. It reminds us that, in both personal and professional lives, we need to be mindful of the diminishing returns of additional inputs and seek to optimize our resource allocation. By understanding and applying this law, we can make more informed decisions that lead to greater efficiency, profitability, and sustainability. Thank you for your attention.。
哲学解释作文模板英文

哲学解释作文模板英文英文:When it comes to explaining philosophy, there are a few key things to keep in mind. First and foremost, philosophy is all about asking questions and seeking answers. It's about examining the world around us and trying to understand the deeper meaning behind it all. As such, any explanation of philosophy should start with an acknowledgement of this fundamental aspect of the discipline.Another important point to consider when explaining philosophy is that it is inherently interdisciplinary. Philosophy intersects with many other fields, including science, mathematics, literature, and art. This means that any explanation of philosophy should also take into account the ways in which it connects with and informs these other areas of study.Finally, it's worth noting that philosophy is often highly abstract and theoretical. It deals with big-picture questions about the nature of reality, morality, and existence itself. As a result, it can sometimes bedifficult to grasp or relate to on a personal level. However, this doesn't mean that philosophy is irrelevant or inaccessible. On the contrary, by exploring these big questions, we can gain a deeper understanding of ourselves and the world around us.中文:谈到解释哲学,有几个关键点需要注意。

爱德华.肯尼迪《美国的真相与和解》英语演讲稿

爱德华.肯尼迪《美国的真相与和解》英语演讲稿Ladies and gentlemen,As the President of the United States of America, I stand before you today to discuss a topic that is central to the foundation and evolution of our great nation: the truth, and reconciliation.It is no secret that the United States has been marred by a deep and longstanding legacy of injustice and inequality. From the forced enslavement of millions of African Americans to the systematic oppression of minorities and marginalized communities, our country has a history that is built upon the backs of the oppressed.But to truly understand the root of these pervasive social problems, we must first start with the truth. We must acknowledge that the harms inflicted upon these communities were not accidental or incidental, but rather, they were ingrained in the very fabric of our society.To be clear, the truth is not an easy thing to confront. It requires us to face uncomfortable realities and uncomfortable truths about our own complicity in perpetuating injustice. But it is only through this uncomfortable process of recognition and acknowledgement that we can begin to move towards true reconciliation. Reconciliation is not simply about forgiving past wrongs and moving on, but rather, it is about actively working to repair the damage that has been done. It is about creating a new future for our country that is built upon the principles of justice, equality, and respect for all people.To achieve this vision for our nation, it is imperative that we acknowledge and rectify the complicity of our government and our institutions in perpetuating systemic injustices. We must work to create policies and initiatives that actively combat these injustices, and we must hold those in power accountable for their actions.But we cannot rely solely on our government and institutions to enact change. Real change must come from the grassroots level - from the average citizen who is committed to building a more just and equitable society.That is why I implore each and every one of you, today, to take an active role in the cause of truth and reconciliation. Whether it is through supporting local organizations that fight for social justice, engaging in difficult conversations with friends and family members, or simply practicing empathy and understanding towards those who have been historically marginalized, we all have a role to play in creating a better future for our country.In closing, I leave you with the words of Martin Luther King Jr., who said that "Injustice anywhere is a threat to justice everywhere." Let us all commit to the cause of truth and reconciliation, so that we may build a better, more just, and more equitable future for all people. Thank you.。

Discussion
The association of economic development with decentralization appears strong. ——Is there evidence that the demand for subnational expenditure grows faster than the demand for central expenditure as income rises? —— If so, why are central officials motivated to meet such demands even when it means giving up resources? ——Independent of democracy or other aspects of the political regime, does economic development strengthen subnational political elites relative to central ones?
Federal constitutions ——Federal constitutions may directly mandate a high level of fiscal decentralization. ——Even if constitutions do not dictate fiscal relations, they may provide political and institutional leverage for state governments to press for a larger share of revenues. The degree of fiscal decentralization might also be affected by another political institution—the party system.

Why are some countries more fiscally decentralized than others?
——Ethnic division ——Country size ——Colonial history ——Economic development ——Democracy ——Federalism and decentralized political institutions
12
Data
Decentralized political institutions ——Countries that had upper houses of parliament that were chosen on a regional basis and which could veto lower house financial legislation ——Not able to find cross-national data for many countries on the centralization of party systems
10
Data
Economic development ——Per capita GNP in purchasing power parity terms Democracy ——The Freedom House ratings of countries’ political rights as of 1993-4. ——A measure of the number of consecutive years that the country had been democratic as of 1995
14
The results
He also found no relationship between the current degree of democracy in a country or the number of years for which it had been democratic and fiscal decentralization as of the early 1990s. Looking longitudinally instead of crosssectionally, there was a very small positive relationship between change in the degree of democracy and in the extent of fiscal decentralization between 1972 and 2000.
5
Economic development
First, decentralization may itself be ‘a superior good, the demand for which is likely to grow with per capita income’ (Tanzi , 2000). Second, increases in development may induce a shift in tastes towards public goods and services that are most efficiently provided locally.
Explaining fiscal decentralization :
geography, colonial history, economic development, and political institutions
Daniel Treisman Department of Political Science University of California
2
Ethnic division
Two types of argument
The first focuses on practical politics. ——Decentralizing authority over such contentious policy issues may help to restrain communal violence or even prevent civil war The second, related argument is about economic efficiency. ——Tastes for public goods and services are likely to vary across ethnic groups.
4
Colonial history
Most countries of the world were colonized within the last two centuries by one or other of the major powers. The colonists introduced systems of government and administration that reshaped political life. The styles and strategies of political control differed markedly.
11DLeabharlann taFederal——One might go by which countries label themselves federal or federations in their constitutions. ——Elazar (1995) ——Riker. Federal states are those that have at least two levels of government, and in which each level has at least one area of action in which it is autonomous.
13
The results
Like several previous studies, he found that fiscal decentralization tends to be greater in territorially larger countries, in those with federal constitutions, and in those at higher levels of economic development. Unlike certain previous studies, he did not find a positive relationship between ethnic division and fiscal decentralization.
3
Country size
Two types of argument
A first reason to expect greater fiscal decentralization in larger states is that there are likely to be diseconomies of scale in government. A second reason to expect greater fiscal decentralization in larger states is that the efficiency argument about heterogeneity.
8
Data
Dependent variables ——The subnational shares of state expenditures and of state revenues Ethnic division ——Gunnemark (1991) : the share of the population that spoke a language other than the official language ——The index of ethno-linguistic fractionalization Country size ——the log of countries‘surface area and the log of their 1994 population
